Peugeot 307 (2001 - 2007) - 03 110, Anti Pollution System Fault light.  
03 110, Anti Pollution System Fault light. - adi-66
Hey Guys.

This is my first post on here.... here goes.

I have a 03 reg 307 hdi 110 bhp.

It was serviced 10000 miles ago at a local garage, However for about 2 weeks it has started to become sluggish (really sluggish.....) there is literally no power, until the turbo kicks in, and woosh away i go.

Today the wife was driving the car and the " anit pollution system fault" light flashed, and then a "Unblock Diesel Filter" message appeared too, both only stayed on for a few seconds. This was accompanied by a total lack of power. The power returned seconds later, and has been ok for the rest of the day.

Ive heard that here is a "Cerium" / "Sirium" dosing system on the car.... could this be the fault ?

Ive tried a fuel additive, with cerium in it..... didnt seem to do anything !! :-(

I need to get a quick fix, as i've just sold the car, and its being picked up soon..... I dont want to call upon my main dealer just yet..... "last time" the Pug went a knacker .... shattered fly wheel!!!! it cost me a fortune !!!


Come on Experts what can you tell me ?!

Cheers.

Peugeot 307 "anti pollution system fault - Screwloose
adi-66

In the exhaust is a soot filter known to PSA as a FAP. It regenerates [a sort of deliberate chimney fire] and burns some of the soot off every few thousand miles. The cerium additive is called Eolys [go Google] and is stored next to the diesel tank with a computer controlled dosing mechanism.

If you don't drive it long enough, fast enough; then the regeneration process won't commence and the filter will block. Take it for a 40 minute blast down a empty dual carriageway; it's unbroken time above 50 [around six minutes] that will start the process.

Alternatively; take it to your dealer for a forced regen. If it's done more than 50,000 they will probably just fit a new FAP and top up the additive. Shouldn't cost more than £6-800.
Peugeot 307 "anti pollution system fault - adi-66
cheers screw loose,

is there any way that i can fill up the cerium tank myself ?

i noticed a old post you commented on saying that its about £30 a liter.... is that true ?


If i top it up, take it for a blast and then have any DTC's cleared all should be back to normal right ?
Peugeot 307 "anti pollution system fault - Screwloose
adi-66

You shouldn't need to top it up yet; that's not the problem here - or is it? That comes up as "anti-pollution additive low" - has that been on and ignored?

The level sensor will need resetting with a scanner if you did refill it yourself. The additive should last 40-70,000m and it's getting cheaper if you buy in big cans.
Peugeot 307 - adi-66
The cars just done 50,000 miles no light has come on saying anti pollution additive low.....

so what do you think the fix is then, that way i can ask a mechanic out the back of the Pug dealer, if he would get the diagnostic machine on it as a foreigner..... its got to be the cheapest way ?!

how do you do a forced re-gen ? is there a way i can drive the car to make it do that ?

i guess 'blocked diesel filter' means the FAP filter in the exhaust ?

and i also guess that 'anti pollution system fault' is being generated by the diesel filter fault. ?

any views ?

Cheers Again :-)

Hi everyone , i have a 2005 Peg 307s 1.6 petrol .... i had this problem the engine management light came on with the warning message saying "de pollution warning" and it was running very rough .... so i came home to look online for the reason why ? .... i cured the problem by removing the fuel cap , and took a clean slightly damp tissue and wiped the 2 tiny magnets on the inside of the cap and used the same tissue to wipe the entire inside of the fuel tank lining where the cap slots in .... i started the car and all light went out !!! and stayed off and drives like normal again, so i assume it was a dirty fuel cap sensor maybe ??? ... plus i filled up on a 1/3 of a tank of super unleaded BP fuel 4 days prior but had the car parked until today... hence i will steer clear of this fuel in future i think ... luckly for me my tank is still going strong using the BG44K fuel additive which i used back in Feb which is most likely re balancing and cleaning the fuel mixture .... anyways i hope this might help someone .

Peugeot 307 "anti pollution system fault - Screwloose
Takeit for a 40 minute blast down a empty dual carriageway;
it's unbroken time above 50 [around six minutes] that will start
the process.


Done that yet?
Peugeot 307 "anti pollution system fault - 1975mattman
I have had the engine management light on for a couple of weeks now.
Also got the Anti-Pollution warning message.Did a code read and got P1446 - unknown fault.
I own a 52 reg 1.4 petrol that has done 50k.
I tried a suggestion from another website - to put in more expensive type of unleaded and the message and light have now both gone out.
However i saw a recent post from you ref this code...
"P1446 is more relevant. It's one of those triple-meaning codes that PSA love and has a totally different description based on fuelling system that generates it. If you've got a Bosch EDC15C2 ECU; then it's "Additive quantity; additive minimum level wait." See above..."

What other info do you need from me to identify what this code actually means as i would still like to sort this out.


Peugeot 307 "anti pollution system fault - Screwloose
1975mattman

[I posted this reply to your identical post last night.]

On your engine; that P1446 code means "Evaporative vacuum solenoid - circuit malfunction." Looks like it was an intermittent fault that's gone away; petrol grade would have little effect.

The EVAP valve bleeds fumes from the petrol tank into the inlet manifold to prevent unburned benzine reaching the atmosphere. It should be on the O/S suspension mount under the bonnet - a black valve with two pipes and a single 2-wire plug.

Should have a resistance of 20-30 Ohms disconnected. If so; clean it's plug with contact cleaner.

i have recently taken my peugeot 307 to a mates garage as the antipollution fault light came up, and the engine has lost all power.he narrowed the problem down to the turbo solenoid valve. i have recently had the diesel particulate filter replaced and also had more additive put in so i no it cant be that.my dads a mechanic so im going to get him to try and sort it.could you tell me where a can find the solenoid valve on the engine and whats the best thing to do first before buying a replacement? we had a quick look last night as i had a rough idea where it was, which was on the metal plate on the front of the engine is that correct and if so there appears to be two valves?please help
Peugeot 307 "anti pollution system fault - ElDopesta

Hi Screwloose,

I have a problem with my 2003 HDi, the fault is showing up as anti pollution, it his been on for about 6 days and the car is running very sluggish. I have access to a ramp at a friends garage who is out of the country at the moment and want to cure the problem my self.

A couple of weeks ago it was showing diesel additive low too, can you please tell me how to deal this one too.

Can you please tell me how this can be done.

Sorry to be a pain, please respond as soon as possible, I would like to do it tomorrow afternoon as I am off work then.

Regards,

All,

Following from my post last night about my problems with my 2.0l Hdi 307.

Did a bit of digging around at work, and found out that I work with a guy that has just left PSA, he used to write the Diag sortware, and lineside download processes :-)

We stuck the Diag 2000 onto the car today and did a bit (Lot) of digging.

Found out that the Cirium tank had 53 'shots' (enough for 23,000 miles) of Cirium left in it and the reason that it wasnt 'dosing' was that the Milage sensor (actually a Hall effect sensor [magnet in the fuel cap]/ neck) was miss reading, and showing open circuit.

The car doesnt actually read the milage that you do before it 'doses' the system, unbelievbley the way it 'knows' when to dose is determined by you opening the fuel filler cap for 5 secs or longer. The FAP ecu then decides that you MUST have added a full tank of fuel.... thus the 500 miles between dosing that everyone talks about !! So if you have a PSA group car, and only use it for short trips, and only ever add a small amount of fuel, the 'Cirium' tank will empty itself very quickly !! On the plus side though, you'll have a lovely clean FAP filter !

Fault was cleared, maunal prime was done [very noisey] (5 times as directed by the Diag 2000) and then repeated 3 further times just to make sure. Car taken for a blast down the Motorway, at 3500rpm in 3rd gear... This made the Regan process Kick in, Que 'tinking' exhaust, and smell of warm underseal !

Car seams to be Fine now.

Of no relevance to me but I love reading about all this behind the scenes stuff - thanks for posting that!
Peugeot CIRIUM DOSING answers. - adi-66
No worries..... just rember if you buy a Pug / Citroen HDI make sure its had its Cirium level checked at around 50k Miles. as its Flipping expensive to by it from a dealer. Oh and theres 2 versions too. depending on your cars model year. I version is a bit more concentrated and lasts longer as its added in smaller quantities.

Specific dosing info to follow.

hi adi-66,

I wanted to ask some questions about the problems you had back in march, as i'm having some similar issues myself. But before I ask you a 101 questions, i wanted to make sure you're still active and will get notification of this message...?!

Hey spider Man.

Fire away with your questions.... ill do my best to answer them for you!
Peugeot Circium Dosing answers. - spider-man
adi-66, first of all thanks for coming back!

after looking at several different sites and several different problems, the one you had seemed most like the issues i'm having with my 2002 307 (110) d turbo.
I'll try and give you a full description of the problems as they happened so excuse the length of this.

We bought the car with approx 72000 miles on the clock back in march07. One thing I noticed when buying it was on the test drive the MFD stated "Check Diesel Additive" - the previous owner told me what this was and assured me that it was just temporary as the car had been in to Peugeot 100 miles ago and had roughly £600 spent on a new FAP plus top up of fluid (receipt to show). Bought the car anyway and all seemed fine until a few thousand miles later - i think at about 75k(ish) the ECU light would come on during driving and the MFD read "Unblock diesel filter". It would go off after a few miles of driving and there was no difference to performance. Fast forward to today, the car is on about 84k and for the last 4000 miles or so the frequency of the "Unblock diesel filter" message has increased; it will almost certainly come on during every trip! I tried doing the manual regeneration a few times since about 80k, but was never sure if it worked properly. WE always fill the tank up so I don't think it's a problem of short trip driving using all the additive.

I've been reading the forums for months now but finally decided to ask someone else's help.

Possibly related to another problem, I've had to call the AA out twice, mid-august (approx 80k) and mid-october (82304 - says the AA report). Both these times the car failed to start, it turned but wouldn't fire. The first time, the engineer was a great help and eventually managed to get it starting after about 45mins of looking at the fuel line etc. The second time, the engineer was probably having a long day cos he wasn't much help. After 20mins of trying he gave up and towed me to the nearby peugeot dealer. Funny thing though was after he drove away I thought i'd give it another go and it started!! I should have really done something about it the first time but one of those things, i neglected it and whilst the car was still going I avoided the expense of the dealer looking at it.
Both times the fault codes read were:
P0380 glow plug/heater circuit a. coherence
P1446 unknown fault code
P1138 fuel supply pressure regulator. stop required but regulation process still active - open circuit or short to ground

My local mechanic serviced the car (at 77k) shortly before the service indicator required it and found no problems - he couldn't help with the growing problem of ECU lights & MFD messages.

Another problem i've been having during the colder mornings is starting up - similar to some other people i've read about, the car will turn but won't fire and during turning the ESP & ASR lights flash alternately.

Coincidence or what, i checked this forum this morning just before setting off to drop my sister at work, and the damn car wouldn't start. So currently I'm on the phone to my mechanic/Peugeot/AA to sort it out. I feel fairly clued up on the possible problems but any input from anyone, particularly you as you had similar issues, would be huuugely appreciated! That way when peugeot look at the car i'll know what to avoid paying - I have finally bitten the bullet and seem to have no other choice but to take it in (provided it starts up soon or can organise a tow).

Look forward to hearing from you.

Peugeot Circium Dosing answers. - spider-man
i'm sure you all know what i mean anyway but the message when i bought the car was "Diesel Additive Low" and not "Check..." as i stated above
Peugeot Circium Dosing answers. - Screwloose
spider-man

Why is this being a mystery? Looks straightforward enough - by HDi standards.

If the FAP was changed and the additive replaced; then the additive control unit hasn't re-set the quantity. This can be caused by as little as a dodgy fuel-flap sensor - if everything isn't just-so, then it won't re-set and thinks that it's still empty - so no re-gens take place and the FAP blocks.

Glow-plug codes on HDi's are almost normal; they don't pre-heat at above-zero temps and the extended post-start heating eats the plugs and they usually have at least one gone; hence the frequently-seen - and ignored - glow-plug code.

P1446 is more relevant. It's one of those triple-meaning codes that PSA love and has a totally different description based on fuelling system that generates it.

If you've got a Bosch EDC15C2 ECU; then it's "Additive quantity; additive minimum level wait." See above...

P1138 is another 3-meaning code. It's well-known on HDi Bosch EDC15C2s as the definition that you've got. A general fuel-pressure problem - possibly your starting fault. Could be cracked injector[s]; failing high-pressure pump; sticking pressure reg; faulty low-pressure pump; [if fitted] or fuel-rail pressure sensor lying.

Watching the rail-pressure in live-data when cranking, non-start, is the crux. Less than 120 bar showing and it's isn't going to start injecting so no go.
Peugeot Circium Dosing answers. - spider-man
ok lol...erm...thank you...i guess it's straight forward to someone who knows!

so in order of you're post...

- hopefully "unblock diesel filter" is coming up because of a fuel-flap sensor and therefore needs a new sensor...hopefully the filter isn't completely blocked up by now right

- glow plugs need replacing??

- it is a bosch ecu - so that one can be dealt with above.

- i understand that the problems you gave examples for are all slightly expensive to fix, injectors, fuel pump etc !? a 'few' hundred £s

i'm glad my issues are trivial to you, that way I'm now somewhat clued up as to what is actually going wrong. Is there any reason that the car wouldn't start on 2nd AA engineer's attempt yet after towing a mile or so it started as normal?! I ask because as mentioned earlier it's currently on the driveway and stuck there until i organise some way of moving it...

Thanks for your quick reply too by the way :)
Peugeot Circium Dosing answers. - Screwloose
spider-man

Let's take you problems in order of priority. The most pressing is the non-start.

There are at least a dozen different versions of HDi fuelling system[s] so, without knowledge of the exact details, please take that into account. [Year; engine size, code?]

At key-on the tank pump [if fitted] should run for about 8-10 seconds. When cranked, the high-pressure must reach a min of 120 bar for the ECU to even switch on the injectors. Get your mechanic, or the AA, to plug-in and read the "secondary [or rail] pressure" figures.

If they're too low, try jump-leads or a boost-charge to get some more cranking speed - or tow it. Once started, it'll crank faster with a warm engine and should re-start OK - until cooled... If the cranking pressure is OK; get them to test all the glow-plugs.

When at idle the pressure should be 298 bar - exactly. Erratic readings show a problem.
Peugeot Circium Dosing answers. - spider-man
Okie dokie, i'll try that to begin with. I'm going to get the RAC to come out so i'll ask him to do those tests. Once i know more i'll post back. Cheers screwloose!

incidently, it's a 2002 2.0 HDi 110. Code - hmmm not sure which you mean so if you can advise further with this information to hand then please let me know how to find it
Peugeot Circium Dosing answers. - Screwloose

For a 2.0ltr; look in the VIN number [in the logbook if it's cold outside] for three letters - RH? something. [RHZ; RHS etc.] The third letter tells all.

When he plugs-in, the ECU will identify itself - it would be handy to confirm it is a Bosch EDC15C2.
Peugeot Circium Dosing answers. - spider-man
Hey screwloose,

it's RHS!

to give you an update, before I called the RAC I gave it a go with my mates heavy duty jumpstart, and IT STARTED!! :) had left it since the early afternoon without trying and then at about 6pm it worked. I wish I had tried it without the jumpstart first cos then I would have known if that truly made a difference! seeing as it was a very cold night previously, could it be anything to do with that? I read about all the people having troubles on cold mornings etc.

Anyways, luckily didn't have to call RAC. Left it running for a while, took it for a spin. Tried it later last night and started. Again this morning, and it started (although I put a blanket over the windscreen/bonnet lol - just in case)

Gonna take it to peugeot this time rather than risk it happening again.

Thanks for your continued support.
Peugeot Circium Dosing answers. - jayvee
hi spiderman i have the same car and the same starting problem!, i was wondering if it was a lazy starter motor on mine as i have changed the battery and glowplugs and its the same. what did peugeot come up with?
Peugeot Circium Dosing answers. - iceskater
Hello fellow sufferers

I also have a 307 (2003 110 2.0 hdi RHS) with an intermittent 'antipolution' fault. No other symptoms however. Goes fine. (for the time being) I've had the ecu read a couple of time and have 4 different faults logged. Last one was 'lambda sensor' fault. Thought I would get a code reader to log the faults myself for a while before changing anything. (garage charge £30 a go for a code read)

I got a new U581 of ebay (£60), nice bit of kit but unfortunately it doesn't seem to work on this model. Will be back on ebay soon. Had a word with 'talktomycar' today and bought an ELM327 from them. (They said it would work or money back £50) Should arrive tomorrow, not convinced that its going to work however. Believe the protocol is ISO14230-4 (KW2000)

All the data I've found about the diagnostic connector suggests that pin 16 is the battery positive. Pin 16 is not fitted on my connector, hence no power for the ELM327. I've got pins 1,4,5,7,11,12 fitted. I believe pins 4 & 5 are ground, pin 7 is K-line, pin 11 is alarm/remote. Is pin 1 or 12 the 12V line. Does anybody know?. Does anybody know of a cheap code reader that works.

Sorry to go off on a bit of a tangent on this thread but sounds like anybody with a 307 hdi will need a code reader/monitor sooner or later.

Interesting to read about the fuel cap sensor. What a rubbish system. I'll try opening the fuel cap every day for a couple of weeks to give the particle filter a good dose of additive just in case this is causing problems.





Peugeot Circium Dosing answers. - Screwloose
iceskater

A Lambda sensor fault? On a diesel.....?? Hmmmm; slight problem with the code definition there. [PSA can use the same code number for three completely different things - depending on which system you read it from.]

None of the HDi's are easy to access; however, the ELM is well-known, so fingers crossed.

Don't bother just opening the cap, you have to add at least 7 ltrs of fuel to get the additive ECU interested.

I have had the engine management light on for a couple of weeks now. Also got the Anti-Pollution warning message.
Did a code read and got P1446 - unknown fault.
I own a 52 reg 1.4 petrol that has done 50k.
I tried a suggestion from another website - to put in more expensive type of unleaded and the message and light have now both gone out.

On your engine; that P1446 code means "Evaporative vacuum solenoid - circuit malfunction." Looks like it was an intermittent fault that's gone away; petrol grade would have little effect.

The EVAP valve bleeds fumes from the petrol tank into the inlet manifold to prevent unburned benzine reaching the atmosphere. It should be on the O/S suspension mount under the bonnet - a black valve with two pipes and a single 2-wire plug.

Should have a resistance of 20-30 Ohms disconnected. If so; clean it's plug with contact cleaner.
Peugeot faults particualr filter fault sign - istar1000
Hi Screw loose!!!
You have your work cut out on here so it seems but a brilliant job you're doing!!

I have just had the warning message come up this week and had it done 37,000 miles has a full service history. 2.0hdi 110 307 54 plate, vin - vf

The engine magament light came on so i took it to my local pug garage and this is what they said
glow plug fault
glow plug relay fault
fuel cap sensor fault
particulate filter pressure sensor fault
differential pressure sensor fault

I had no warning signs one day, drove it for 10 miles and then it was tested and these 5 faults popped up. the garage reset the faults and said to come back when the fault light comes on to identify a singular or more faults, as they thinks its just one or two faults having a chain reaction. what do you think
thanks for your help

On Wednesday 16th I filled up my 307 sw at the filling station and inadvertantely dropped my filler cap. Did'nt think to much of it but noticed a small magnet stuck to the side of the car near the bottom of the rear passenger door. I picked it off and put it in the glove box as I was not sure where it came from.
Carried on as normal with no fault lights on the display but after about 120 miles the Anti polution warning and fault light came on. I have been looking on various forums then came across this one about the filler cap. Am I right in assuming the missing magnet probably caused the fault warning, if so should it re-set if I put the magnet back in, would the dosing tank empty itself ( no warning message as yet ) or stop dosing altogether and if it does not re-set how do I do this.
Peugeot Circium Dosing answers. - Screwloose

There is a fuel-flap sensor in the system and if it fails to read, the additive ECU could well stop dosing and the regenerations would stop.

If you can see the position that the magnet came from, replace it and see if the light goes off. If not, it's time to find a dealer or diagnostics place with the right kit to clear it.
Peugeot Circium Dosing answers. - iceskater
Interesting about the magnet. I just checked my filler cap and sure enough there are 2 magnets on opposite sides recessed in the plastic. They are a brownish colour. I suppose it would be possible to cope with only one magnet if you knew where the sensor was located and were careful to put the cap back in the correct orientation.

Back to me trouble codes
The first read by the local gagrage resulted in the following codes & explainations

1429 - oxygen sensor
0243 - turbo waste gate
1112 - diesel pressure control
0340 - phase sensor

These were cleared but the antipolution fault came back a day later.
They read it again and got 1429 again. Re-cleared it but came back straight away without the engine running.

They said they must replace the lambda sensor. I agreed and we booked it in. Later I reconsidered and cancelled the job thinking I would live with it for a while & log the faults for a few weeks with my own fault reader to see if it was the same fault every time.

After a bit of digging on the internet I discovered some of the codes had a different meaning for a peugeot 307 2.0 hdi

1112 - intake air temp
1429 - particulate differential sensor value
0340 - cam shaft position fault
0243 - turbo waste gate

The car had a new cam belt fitted a week earlier which could explain 0340. I had replaced the pollen & air filters recently and had checked the condition of the connector terminals on the plug that went on the air box. This must have been the intake air temp sensor & explains 1112. Just leaves 1429 & 0243.

I've come to the conclusion that there maybe 2 real faults. A faultly pressure sensor or leaky/blocked pipe & a dirty/worn EGR valve. The car has done 115k miles. Goes great, but is sometimes a bit lumpy on tickover. Could a dirty/faulty EGR valve cause lumpy tick-over?

Haven't had a chance to see if the ELM327 will read the codes yet, hopefully try that tomorrow.
Peugeot Circium Dosing answers. - Screwloose
iceskater

Not only do you need the car and engine code to define some PSA fault-codes - you also need to know the make, type and level of the management system. Precision is everything, guesswork will get you straight into trouble and easy it ain't.

IF - you've got a Bosch EDC15.C2; then:-

P1112 is fuel pressure below minimum value. Very common - never nice.

P1429 is particulate filter differential pressure sensor value. Coherence of the differential pressure when engine stopped.

P0340 is camshaft position sensor A; bank 1. Circuit malfunction.

P0243 is turbo wastegate regulating valve A. Circuit malfunction. [Nothing whatsoever to do with the EGR.]

Does that clarify things a bit?


If your garage really offered to fit a Lambda probe to a diesel, just pity them and find a competent garage - the laughter when they asked for one in the dealer's parts dept must have echoed through the building!

That's a classic!

Peugeot Circium Dosing answers. - sedohr
hi screw loose my name is sedohr and i have just registered with the site.
I too have been having problems with my engine rough idling, the fuel filter message has also been coming up so i have changed the filter. problem with idle is still there. I have read the message board right back from marh 07 and i have found it very intersting especaily when i got to the last message.
I have just had a diognostic check done tonight off a freind of mine that runs a garage for hgvs and light commercails and where able to use his computer to read my ecu.
ther where 4 insignificant faults and one fault that said it was the EGR solenoid control. What is this, and what does it do, could this be causing my engine to idle roughly.( it tends to slow down and change note).
thanks i awate yours or someones response.....
Peugeot Circium Dosing answers. - Screwloose
sedohr

What car have you got? What year? What size engine? What is the engine code? What make of ECU is fitted?

Exactly what did the message say? Which filter did you replace?

Exactly which code numbers did your friend find - all 5 of them?
Peugeot Circium Dosing answers. - sedohr
Hi screw loose,
i never expected a response so soon but i only did the test on a spare of the moment thing and i never took note of any of the codes in fact i dont think it listed any codes just descriptions of the fault.
i will go back tommorrow and do the check again and write down the faults.
i drive a 307 2.0 110hdi with a bosch system on it. its a 2003.
I replaced the fuel filter about a year ago and i dont think it has said it again. My wife mainly drives the car and she doesnt always notice the messages.
thanks for you speedy response

Have a look in the middle of the VIN number of your car for the letters RH. The next letter will identify the engine type and whether it has a diesel particulate filter.

I don't think that there is a message to replace the fuel filter, if it said "Diesel filter" it meant the one in the exhaust.

The exact code numbers are vital - there are 3 thousand to choose from.

Is it misfiring at idle - or is the dual-mass flywheel coming apart? Many HDi "idle misfires" are the flywheel.

the next letters after RH are SB
Peugeot Circium Dosing answers. - Screwloose

That makes it an RHS, which does have a particle filter in the exhaust; get those code numbers tomorrow and we'll take it from there.

Just bought a 307 hdi 2.0 (110). The diesel additive mininum level low is showing so I know I need to get this filled up.. The guys I have spoke to at garages have asked the mileage (89000) upon which they say oh dear you will need a new filter! How do I know I will need a new filter? Should a message come up? or are these garages trying to knock me up into buying a filter before I really need a new one? Not sure if its had new one put in yet, it has full service history and seems to be running fine... any ideas on this anyone?

Many thanks James.

The system should have been serviced at 50,000 [few are.] New filter, new additive, system re-set with suitable equipment. [It was supposed to be filter pressure-washed; but then the EU Waste Directive and the 'Elf and Safety got involved and a factory-reconditioned filter became the cheapest way.]

As it's been left so long, then the filter will be restricted by unburnable residue and a recon one will likely pay for itself in better power and economy. There is a message if it gets too bad - "Diesel filter blocked," but by then it will have trashed the sensors too and they cost big money.

Sadly; this is just part of the brave, new, green, world.
Peugeot Circium Dosing answers. - honestjames
I went to a peugeot specialist today...not a main dealer. I asked him to quote me on filling up addidtive and new filter and he said it would be expensive. He then pulled me to one side and said he could re set the ECU so as it no longer took notice of these warnings and in effect turn of the FAP system... he said it wont effect the running of the car but will just mean more emissons... would this ruin the exhaust system and damage the car?
It would cost £60 which beats the £570 peugeot main dealer has quoted me!
Any ideas if this is kosher ?
Peugeot Circium Dosing answers. - Screwloose
James

It's easy to disable the system; the only problem is that the FAP then clogs up and everything comes to a grinding halt.

Even after de-catting and fitting a plain pipe; [not for £60!] you've still got to fool all the sensors - not easy - and the whole system is interlinked and networked, so grief is nearly assured.

Then there's the legal and insurance issues - de-catting's a power mod, so your insurers will be interested - as will the DVLA if you're in a emission-related VED bracket. It can't be long before this will come into the MOT.

£570 is not a bad price - just smile, pay-up and keep the fluffy bunnies happy.
Peugeot Circium Dosing answers. - honestjames
ok i am going to bite the bullet and go main dealer...one last question though if you dont mind... Say I get the dealer to fill up the additive and re-set the ecu, if I carry on driving and the warning for blocked filter does not come on does this mean I will be ok for a while?
When I was at the main dealers they pretty much said its going to need a filter and i could see pound signs in his eyes! (I know how the trade works and they will always charge as much as they can get away with) Can the filter be in a poor state but you can still drive around ok? They said they could do a diagonistics test to see exactly what needs doing...Will average joe like me be able to make sense of this read-out? I dont want a filter if i dont need it and as I said this might have already been changed or been cleaned.
Peugeot Circium Dosing answers. - Screwloose
James

If the system had been serviced at around 50K, then it wouldn't have got to this state. Warnings shouldn't ever come on on a properly maintained FAP system. The dealers computer will know if it's been done.

Yes; you can re-fill/re-set the additive quantity on it's own - if they'll do it because of the risk of a comeback. If you let the filter block; it'll likely take the sensors with it - more £hundreds. A diagnostic test only measures current loading - there's no way of telling how much of that won't burn off at the next regeneration.

Surprisingly; most of the trade is very honest, don't overcharge and hate the crooks that do even more than you.

Hi

I new to Peugeots and Forums
Bought a 04, 307 2.0 (110) hdi a week ago, under 24k miles with a good service history and tracable history.
Yesterday I put some fuel cleaner in the tank 'Grease lighting'.

After driving for a couple of miles the 'anti pollution warning message came on, yellow engine sign on the dash and the engine appears to be limited to less than 3000 revs. I filled up with more fuel to ensure the additive mix was not too strong. however the warnings did not go out

I followed the earlier advice and took it for a 40 min run on the motorway however it was hard to push the engine due to the rev restriction, unforturnatly this had no impact
I spoke to the suppling garage (did not mention the addtive) they say it not thier problem, expected response. I will keep trying with them.

Regarding the warning message what do you think the problem could be and a gut feeling on cost would be a great help

Thanks

Kevin

If the vehicle has been brought within the last week, it is clearly their problem
Peugeot 'Anti pollution warning message' - Screwloose

Never put anything in a common-rail but premium DERV [or, preferably, red diesel if you can use it.]

Does this "grease lighting[?]" additive say that it's safe for diesels with a DPF in the exhaust? Which one of their extremely dubious-looking range did you use? [They sell it at Screwfix and on the Shopping channel, so it must be good!]

If you've told the supplying dealer that you've possibly damaged the car by doing this; then maybe just get the fault code[s] read and come back with them.

No regenerations will take place while the car is in limp mode with the light on.
Peugeot 'Anti pollution warning message' - bayjon
Screwloose,
I have a 02 1.4HDI 307, with 181K, never any trouble with this car, really.
Needed a new temp sensor, and new air flow sensor, got a new timing belt.
Recently I got my anti-pollution fault, left it up with my local mechanic, a good guy, he plugged it in, and it showed I needed a filter regeneration.
I took it too my local Peugeot dealer, they regenerated the filter, and also changed the crank pulley.
Drive the car home, no problem, no anti pollution. 2 hours later, jumped in the car, light back on.
Brought it back in to Mr Peugeot, he tells me he can find no fault, just drive the car.
Light persists on and the car is drinking juice, about 450 miles v 590 miles.
I brought the car back to my local guy again, his machine says air flow sensor, after much bull, the peugoet dealer sells him one.
The new air flow sensor is fitted, clear the fault, no problem.
Next morning being Saturday, the light is back on, I do my 40 mile Motorway drive and it is still on.
Last night I get into the car and no light.
This morning light back on.
This evening leaving work the light comes on and I get my anti pollution fault, but 5 minutes later it goes out. This evening I switched the car on and off about 5 times but it remains to be seen.
I checked the fuel filler magnets and they are still thier.
Have you encountered this problem before our can you advise.
Thanks in advance.

Unless there's a circuit fault at key-on self-test, then it's odd that a MAF flags a code before the engine's running?

There's at least a dozen MAF codes available to it; which one did the ECU pick?

the engine light and fault shows on start up(my apoligies)
I undertook 6 journeys today, and on 2 of these the light went out after a short drive.
The car has become hard on fuel, ie 45mpg v 53mpg.
It is frustrating me that the problem is sparadic, and that my Dealer says drive it and see if it gets worse.

Hex codes are only of use to the dealer's machine. [Clearly you're using unmodified copyright software that was blagged straight off the PSA dealer tool - useless.]

Hi,Im new to the site & would like to say thanks for all the help/ideas.
My Car:-
Peugeot 307 03 2.0 110 HDI SW

My Anti pollution fault was intermittent. Turned out to be faulty air flow meter/connection.

My main fault on the car was no power when cold but ok when warm.
After much fault finding, over due repairs, to cure the problem, I was a lot out of pocket & no fix.
After my own research and old knowledge the problem was fixed.

The air intake goes via turbo either direct to inlet manifold or Via the inter-cooler. This is controlled by two valves. The direct one in my case is stuck shut, so little or no air to manifold.

The solution was to remove vacuum pipe form the inter-cooler valve & cap the same.

(The over due repairs were not down to me as I only bought the car April 07)

hi screwloose, i have a 51 plate 307 110 hdi, love the car but ever since i bought it the auto diagnost light has been coming on on the dash and unblock diesel filter along with beep, all at same time!, no performance loss really but light shouldnt be on and covered by warranty, it has been in twice already and not been remedied, they say they cant get it to come on in the garage and they have test driven it but as soon as i picked it up from the garage i only drove about four miles and on it came again. error codes were (before it went into the garage) p01435,po1446,po1448 from memory, i havent had time to check them again since it came out of garage, additive has been topped up and counter reset, regen has supposed to have been done, but obviously something still wrong, please help as its doing my ti!s in!
p.s. new to this site so its probably come through to the wrong place, hopefully jayhdi
Peugeot 'Anti pollution warning message' - Screwloose

If it didn't get the system serviced at the recommended 50,000 miles; then this will happen. It runs out of additive; [P1446] develops a second fault with the additive system itself [P1435] and the filter blocks solid. [P1448]

If it can't regenerate, then you'll have to fit a re-con one. Also check the additive ECU is now correct with it's quantity and fully functional.

Now you know why it was sold.

Peugeot 'Anti pollution warning message' - jayhdi
so what it needs is new filter,magnetic counter reset and regen and all should be well??
Peugeot 'Anti pollution warning message' - Screwloose
jay

Not exactly; as well as being empty, there would appear to be [have been?] a fault with the additive system itself [five different meanings to that code - on this system alone] which needs addressing.

A new filter will re-gen if the additive system is functional. If it isn't; then it will quickly block-up and you're back to square one.
Peugeot 'Anti pollution warning message' - jayhdi
ithas had additive topped up already,what do you mean by functional, what would you say needs to be done and checked
Peugeot 'Anti pollution warning message' - Screwloose

The additive quantity won't re-set and the system won't work if P1435 is still present. The cause of that needs investigating.

Hi all
I finally got my antipollution warning to go away.
One of the fault codes I was getting suggested the 'FAP differential pressure sensor' was at fault. I replaced it but fault was still there. It was only after I blew the sensor pipes out with an airline that the fault went away. Wish I had tried this before buying the sensor (£85).

hi Screwloose,
hi all,

I have a big problem! My peugeot is 307 2.0 hdi RHY engine code.
The antipolution fault code comes up some times and no more than 2600 revs.
Sometimes i have no thottle on the car when i wait on a red light and i try to go on! The revs won't go more than 1200.
I don't what to do anymore! Please advice!

Error codes was:
P1113 - IAT Sensor open/short
P0113 - Intake air temperature signal. Short circuit to positive or open circuit
P0102 - Flow sensor signal. Open circuit or short circuit to earth
P1198 - Pump rotor control underfueling

I disconected the MAF/IAT conector to see if the car is going better so that explains the first 3 codes.
I already changed the fuel regulator on the high pressure pump twice!
The problem is not permanent. The car is going fine but sometimes I have to thottle for few seconds and (after that) I get the antipolution fault and revs limitation to 2600. If i stop the engine and restart the limitation goes away but the antipolution faul eroor remains on the comptuter until I start over few more times.

Please advice! I don't know what to do with this car.


Peugeot 'Anti pollution warning message' - Screwloose
nforcero

PSA codes are system specific. P1113 is as stated only if, as looks likely, you have a Siemens SID 801; on that system only, P1198 is:-

"Diesel high-pressure monitoring; volume control valve at maximum."

That one can cause limp mode. The P0--- codes are about right if the MAF is off. [Not the problem.]

So we'll need to confirm the make of ECU fitted first.

For the total lack of throttle; there are no throttle codes, so the brake-light switch adjustment is a possibility - that can cut the throttle right off.

Have you changed the fuel-filter and was it always pump diesel in the tank?
Peugeot 'Anti pollution warning message' - nforcero
Thanks for fast reply!
I have a Siemens SID 801. And a Siemens high pressure pump.
I put only diesel in the tank and changed the fuel pressure regulator (the one from the pump) and fuel filter twice already.


What do you mean by "Diesel high-pressure monitoring; volume control valve at maximum."?
I don't understand. The code reader said something like "flow regulator at stop".
I have no problem on the highway. Everything starts in the city, where is a lot of traffic lights!

The car seems to run better with the climatic air ON.

1. when I start the engine I can see some air in the tubes to fuel filter and to fuel pump. And some on the tube that goes back to fuel tank.
2. when the throttle goes off, if someone push on the manual rubber pump in the engine compartment, it comes on again! I don't know what to do anymore...

Please advice!

Peugeot 'Anti pollution warning message' - Screwloose

An air leak into the suction pipe would fit with the code; the volume control valve [flow/pressure regulator] would be at maximum and the pressure not rising.

Get the front to rear fuel pipe and the tank pick-up checked for leaks.
Peugeot 'Anti pollution warning message' - nforcero
done that.
everything seems to be ok. no leaks
Peugeot 'Anti pollution warning message' - Screwloose

If you've got air coming up from the tank; "seems to be" is not enough.

Air could be coming in anywhere; a mm by mm examination of the pipe and pick-up is needed.
Peugeot 'Anti pollution warning message' - nforcero
after I start the engine the air is not there anymore. only when it starts i can see some air.
what about the error code and sthe stop lights switch?
i need help! peugeot garage does not know what to do. they said that the high pressure pump is the problem. the car has only 66.000 km and is running very good.
but sometimes.... it does not.
screwloose? i put my hopes in you. till now you are the only man that seems to know what he's talking about.
Peugeot 'Anti pollution warning message' - Screwloose

So the air in the pipes is only there for a few seconds?

The error code means that the ECU is trying to increase the rail pressure [pump inlet valve at maximum] but the pressure still isn't rising enough.

The new fact that the throttle comes back after pumping the primer, would suggest that there's not enough fuel being fed into the high-pressure side of the pump and it's not a brake-switch fault.

Make very, very, sure that there's nothing blocking or restricting the fuel flow - anywhere. Take the tank unit out and physically check the in-tank strainer.

If the strainer and the fuel line are perfect; then it could be the suction side of the pump. You may be able to get a diesel specialist to fit new valves into the pump - possibly?

Did you see any metal particles in the original fuel filter when you changed it?
Peugeot 'Anti pollution warning message' - nforcero
The air is for few seconds.

"If the strainer and the fuel line are perfect; then it could be the suction side of the pump. You may be able to get a diesel specialist to fit new valves into the pump - possibly?" - i don't understand what valve are you talking about. It is like the fuel pressure regulator (the one from the pump)?
Can it be changed on the car or should i take out the pump?
The tank is clean, washed out. The pipes was cleaned with air under high pressure.
In the fuel filter was no metal particles - it looks just perfect.

What then?
Peugeot 'Anti pollution warning message' - Screwloose

The Siemens fuel pump also contains a suction pump to draw the fuel from the tank.

There is no fuel pressure regulator in the conventional sense. It uses a volume control valve [flow regulator - call it what you will] between the outlet of the suction pump section and the high-pressure pump.

Get an injector leak-off rate test done next. If that is OK; then, if you can't get the suction pump tested or repaired where you are, you may have to change the whole pump as a unit - at great cost.

But be very sure that there is no air getting in while it's running - I don't like the sound of those bubbles, even just when starting.

Peugeot 'Anti pollution warning message' - nforcero
I did it!
I used a bottle to start the car. The pipe was directly in the bottle and the return one the same. It runned just fine. I got some limitations to 2600 rpm and antipolution fault for few times at the beggining but the fuel pipe was directly in the pump (no filter), so some sensors was probably skipped. But no problems with the throttle!! The rpm at idle was about 800rpm instead of 880 rpm before!!
I don't know what to think.
I done something like that before... just with no fuel filter (right after I cleaned the tank) and the car was running perfect for one hour test in hard conditions.
I put a new filter (an entire filter) and had the same problems... so I don't think that the filter is jammed.
I put everything back on as usual and the car worked just fine on my way home, no limitations or errors, no antipolution fault. No problems since the experiment. But it will be back! Any ideas?

Peugeot 'Anti pollution warning message' - Miss K
First time to site, great posts about this problem and thanks SO much for all the help and advice especially to Screwloose - genius, thank you!

DETAILS: '03 reg 307 HDi D Turbo 110 68K with intermittent messages for at least 6 weeks - Antipollution Fault and Diesel Filter Blocked. Also loss of power as prev posts describe. Taking car to dealer for diagnostics tomorrow.

Please, if I may, ask some more advice but hope not to repeat stuff detailed already, I am mainly concerned the dealer will mis-diagnose and charge me too much for stuff that won't fix my prob (NB quote from Sedg 'I have booked it in for next week so that they can do further checks, the only concern I have is that last time the car was there they was going to sell me a new BSI unit and a FAP filter!!! I guess I just need to be more inquisitive about what is required').

HISTORY: Local (good) garage initially drained water from somewhere and also gave it a run (can now assume this was to regen filter- as posts detail). Prob was briefly fixed, but returned. Garage recommended return to dealer for new FAP filter. When I realised cost (£460) I started investigating prob myself. (Bought car in December 07 and already have had wheel bearing replaced, 4 tyres, temp sensor gone).

1)My current concern is the cost of the sensors that may have 'gone' (read about in prev posts) as 'diesel filter blocked' has been appearing - does anyone have an idea on what the sensors are that may have gone and approx costs please??

2)I am planning to explain to the dealer the symptons of prob, will not mention visit and advice from non-pug garage, and then ask for codes to cross ref with posts on this site when dealer phones with results from diagnostics. Is this the best policy??

I want to try and give the garage the impression I know what I am talking about so I get a good deal and honest diagnosis - sorry for being cynical but as a female who knows nothing about cars I am sure they see me coming!

Thanks again for all posts before this and anything else anyone can add that may help.

MissKeri

Thanks for the kind words; but don't think that the average man know any more about the technicalities of cars than ladies these days... [Or many garages come to that...]

As you'll have gathered; the "diesel filter" referred to is the FAP - so many garages think it's the fuel filter.... [That will be where your garage drained the water trap.]

1/ It's likely that the differential pressure sensor that measures the pressure fore-and-aft of the FAP may need changing - as well as the fuel cap sensor. Nothing can be said for certain - but a high probability exists.

2/ A good move; ask for a diagnosis, a print-off of all stored P-codes and a, broken-down, quote for repair.

Could I briefly interject that I feel this thread has been brilliantly handled by all concerned and will be a mine of information to many who come after.

I am really impressed that someone of the calibre of Screwloose is prepared to give so much time and patience, and share so much of his invaluable knowledge (and at all times of the day and night, I might add).

I'm afraid the problems raised here confirm my sad conclusion that, when the time comes, I will not be replacing my much-loved 306 HDi with any subsequent PSA diesel and probably not with any kind of diesel.

Peugeot 'Anti pollution warning message' - Miss K
OK warning messages did return and been to garage now.

Result was FAP blocked and sensor needing to be replaced. Total cost to replace filter, replace sensor and labour inc VAT £614. Also paid £94 for diagnostics (1 hour). After querying how long it took them to diagnose they will take 1/2 hour off my £614 bill when it gets fixed (1st Dec). They said it takes 2 1/2 hours to fix although a local non-Pug garage said it should take no more than 45 mins?

Anyway thanks so much for all your advice, I am an 'Honest John' convert now and will always consult for any motoring decisions! Pug garage service guys actually commented on how well informed I was, so thank you very much indeed.

Did they offer an opinion as to why it blocked? I don't see an additive refill/counter re-set in that list?
Peugeot 'Anti pollution warning message' - Miss K
No - so I will ask when I take it in (1st Dec) - I know the cost includes the fluid (presume that is the additive refill you mention?) and will check the counter re-set is done. Thank you for your meticulous attention to detail - superb.

Hi all and thank you to everyody for all the great information on here. I too have seen all these errors on my 307. Its a 02 307 D turbo 2L HDI 110BHP "RHS" from the cha. number.

AT 87K i brought it to main dealer with the antipolution and the unblock diesel filter faults on the mfd (they had been on for about 20K!!). To cut along story short fap was blocked and additive was empty. Got FAP and pressure sensor replaced and the additive topped up. After this car was fine and no errors until now.

Car now has 127K on it and the unblock diesel filter error has just come back. I have had it on 7 or 8 short journeys since error reappeared totaling no more than 150 miles and error is there 90% of the time.
Learning from the last time i checked out the additive tank and it is empty. I am hoping that the particle filter will be ok once i get some additive in there and get a couple of regens done.
Has anybody out there ever topped up the additive successfully themselves or will i have to take it back to peugeot to get it topped up? I am not concerned with filling it, if i could get a couple of litres in there that will be enough for me to be able to sell the car.

If i was succesful in a DIY top up will regen occur without geting the reset done on the ECU by dealer?
What is the best method to force a regen? i have seen different posts from having it above 3500 revs for more than 6 mins to having it over 50MPH for 6mins, which is correct?
I have it booked into the dealer for next Friday 5th December but would love to avoid this cost as i am about to advertise the car.

Peugeot 'Anti pollution warning message' - Bcolemax
Just an update.

Car never showed any message to say that the additive was low this time or the last time problem occurred. I have bought a 3L refill kit from Peugeot for a cost of ?107 which came with pipes etc needed and have put it into the car (easy enought to do if you have a pit or away of lifting the car to access underneath)
I will test car on thursday when i transfer the insurance for a couple of days and get it out on the motorway. According to a friend in Peugeot i will have to take it in anyway and hook it up to the diagnostics to have the ECU reset. Will let ye know how i get on.
Peugeot 'Anti pollution warning message' - Miss K
Just an update (apologies for length, but hope this helps others):

£730 inc vat for new filter, new sensor, new fluid, re-set and labour. Apparently it was blocked because 'it got blocked with stuff that wasn't burning off'.

[Pug said fluid should be 'replaced' at 48K (although I read in my manual 'maintenance should take place on the filter 48K' - so assume same thing). Pug said filter would be advised to be replaced at 72K anyway (on 68K now so suppose I have saved a job for later?)].

Anyway I drove it for few days and light came back on again, grrrrrr, so took it back in yesterday. They have now fixed it as they said the sensor wasn't fitted on correctly (Do'h... presuming of course that this was the garages fault as they replaced it, but no real admittance there from Pug dealer!). Didn't pay anything but they drove for 60+ miles trying to work out the problem.

Whilst driving around in my car they also noticed a number of other faults. I was aware of them all (pretty minor things) except that apparently the fly wheel for the clutch is making a 'ting' noise and is disintegrating. They mentioned this is expensive (£300+ for parts and 7.4 hours labour @ £80p/hr). They didn't give me a timescale for this problem so will phone them tomorrow to see how urgently it needs doing.

Probably going to try and sell the car in the new year as I am so fed up with it. Bought it for £4995 in Dec 07, spent £1775 on it this year (inc MOT and 4 new tyres). Presume this is extreme???

Will check the other thread on fly wheels ! At this rate I'll be able to re-train as a mechanic.

(After thought to Screwloose - didn't mention it before but before the warning messages started I had to be towed back from Bristol (to Maidenhead) because the air intake pipe was collasping. Was wondering if this would have started off the anti pollution message initially ??) Thank you for all your help :o)

Hi Screw loose,

Once again as everyone keeps saying you seem to be an absolute genius.
I have just had a reconditioned engine fitted on my 307Hdi 90bhp 2002 RHY. The cam shaft I think went on my old that was the only reason I had to get a new one.
On fitting the new one everything was swapped from original engine to the new one. Apart from fuel injectors which I had from a company specialising in pug parts. Upon cranking over for ages the car finally started. The exhaust is pumping out horrendous amount s of black smoke. And the Anti Pollution fault is illuminated. We were under the impression the injectors may need to get remapped or reprogrammed. We took it to the garage and they diagnosed it with a few faults. Could you possibly shed some light?

The Garage gave an explanation of each fault, but we need to know what can be done as they didn't shed any light. seems strange as no fault was registered befoe we swapped it over.

P1641 P1210
P1197 P0481
P1356 P0480

From the top:-

P0481 Cooling Fan 2 - Control Circuit Malfunction

P0482 Cooling Fan 3 - Control Circuit Malfunction.

P1164 SID 801 - Fuel pressure signal.

P1176 SID802 - Fuel flow regulation fault. Coherence.

P1197 Key off voltage low / Piezo-electric injector, power stage.

P1210 Injector control pressure above expected level.

P1356 Not listed for this vehicle/engine. Recheck code.

P1641 SID801 Piezo-electric injector, power stage.

What have you done? The only conclusion that I can come to is of some horrible mis-match between engine and fuelling system.

What make of fuelling is fitted? Why were the injectors changed?
Peugeot 'Anti pollution warning message' - bro_kad
Screwloose

Thankyou for the prompt relpy, the recon engine that came was a bosch fuel system and we changed it to seimens from the old engine. they were changed as one snapped whilts trying to remove from the old engine.

Is there anything you can think of we can do?

Regards
Peugeot 'Anti pollution warning message' - Screwloose

Did you change everything over? The pump, the rail, all the sensors?

As Piezo injectors are super-fragile and will never survive removal; were these new injectors from an impact-proof casing?
Peugeot 'Anti pollution warning message' - bro_kad
Hi, Screwloose,

YES everything was changed, i am unaware of the injectors conditions as there were brought from a pug used parts dealer.

So are you suggesting that a new injector system is needed?
Peugeot 'Anti pollution warning message' - actl
Hi Screwloose,

I came across this post and would appreciate your opinion.

I drive a 5+1/2 years old Peugeot 307SW 2.0 litre petrol in Singapore.
VIN is VF33HRFNF83158175.

About 2 years ago I had the dreaded Anti Pollution Fault warning light first pop up. Since then, the warning light has been permanently on, except when my car is in Peugeot / Autofrance for servicing when they reset it. But it comes back on soon after.

The P code is P0410 : Permanent fault. Air injection at exhaust. Malfunction.

The workshop tells me this is due a build up of carbon in the engine. Which would normally occur in any petrol engine anyways. Except here it is picked up by the sensor. Based on the advise of the workshop, I am using higher grade/octane petrol with fuel additives and also tried engine flushes during servicing with no success. I don't think it is really necc. and worth the cost to overhaul and decarbonise the engine.

Do you think this is the problem ? Appreciate your thoughts.

Thanks, actl

Hi Screwloose

I have a few problems with my Peugeot 307, I needed some advice so I don?t get ripped off.

It?s a 307 HDI 2.0 D Turbo 110 BHP, 53 Reg, about 52,000.

The Engine management light is on and often while driving the dial flashes STOP
?Engine Coolant Temp Too High?, Also it will say quite often ?Anti Pollution Fault?.
The car doesn?t drive the same, infact it?s quite sluggish.

I have took it too Peugeot whom wanted a ridiculous amount to fix it.

This is what the report says.

Engine ECU

EDC15C2
Permanent fault, EGR solenoid valve, EGR solenoid valve circuit short-circuited to earth or open circuit.

Permanent fault, Particle filter, PEF pierced or differential pressure info incorrect.
Intermittent fault, Engine coolant temperature signal, Short circuit to positive or open circuit.
Intermittent fault, Additive quantity, Additive ECU.
Intermittent fault. Additive quantity. Maximum additive in PEF threshold reached.

They also said if you sort the top two (as above) then all faults will go.
I've also been told to fit a EGR Valve, but if it's only a loose connection I'm completly wasting my money. Where can this EGR valve be found?

What?s the best and cheapest solution? And how much should I be paying for this work?

hi ice skater sounds like i have same problem is your a 307 hdi rhs same as mine and is it the two metal pipes on the dpf you blow out 1 at the front of it and 1 at the back if so do you need yo disconect the sensor and where is it locted thanks

Hi. I went to a garage today with the same problem 'anti pollution fault' with me 55 reg 307s which has 37k on the clock. Got told it was something to do with the timing belt and how its compartments are not in sync with eachother. Anyone heard that before?? I only bought the car in this January so i will be complaing hard until the dealership fix it for free as i was told the belts had al been changed, but no one seems to have a similiar problem to mine on here. :S confused!!

03 110, Anti Pollution System Fault light. - Driving Instructor
Hi Guys am new to forum so I hope I will be able to find this message and subsequent replies.

I have a peugeot 307 1.6hdi on a 55 plate 128000 miles 12000 mile service from new.

Many many thanks to screwloose for the info he has published on here, if only I had discovered this forum ealier!!!!

I have spent approximately £600 mainly for a peugeot diagnostic x 6 for them to tell me crap.

I have an engine warning light with a display that says anti-pollution fault. The fault code: po 405 and po 489

I can make the engine warning light go out by running it to the point of running out of diesel then filling it to capacity. This makes the engine warning light stay off and the anti pollution sensor warning does not come on............. for at least 4 or 5 starts. This is most of the time.

The problem I have is: as a driving instructor I stop and start the car more then most, up to 20 or 30 times a day. I have had this car from new and it has had a very very hard life compared to most ordinary cars.

All advice given will be gratefully recieved. My car does not have a serium injector fuel additive dubris fitted.
03 110, Anti Pollution System Fault light. - Armitage Shanks {p}
Well you are lucky not to have the EOLYS injection system - are you sure you haven't? It usually goes with a DPF. Your problem is the stop/start low speed nature of most of your driving. It is widely reported that DPF equipped cars ,and not just Pugs, need to be given a good hard drive quite often. I now drive mine around in 4th gear out of town and when not on M ways, to try and keep the revs and the exhaust temp up. I am just going in for a 5yr/50K service on Tuesday - I will report here if any DPF problems are found. I have no warning lights but the car seems to spend a lot of time regenerating the DPF.
03 110, Anti Pollution System Fault light. - Driving Instructor
I dont know what a eolys system is.

DPF is just as confusing.

I am really sorry to be so thick but I just teach people to drive them. ha ha ha ha ha

Peugeot dealer did check to see if I had the fuel additive thingy and they said "I did not have it."

I have in the past driven in 4th gear for half hour and kept the engine speed up, stopped restarted the engine with no warnings or lights everything as it should be. Stopped restarted the engine and the anti-pollution warning is on and the warning light.

I have run it to the point where I am going to run out of diesel, then refilled to the brim and everything is good for 4 or 5 starts.

How would I know if the car is regenerating the dpf?

Many thanks
03 110, Anti Pollution System Fault light. - Armitage Shanks {p}
This is very long and technical. If you read it you will be better informed but not much the wiser!

www.dieselnet.com/papers/9909rhodia/

I know that my car has tried to re-generate as, at least twice a week, when I park and stop the engine, the cooling fans roar away for about 10 minutes. This is a sign of an interrupted re-generation, I believe. Some people say their cars only re-generate 4 times a year!

Edited by Armitage Shanks {p} on 24/05/2009 at 15:50

03 110, Anti Pollution System Fault light. - Driving Instructor
Awwwwwww nooo it gets worse.......... My car will keep the fans running until the battery wears out. It does this at least once a month.

I now listen for the fans after I have turned the engine off, if the fans are still on I will go back out after ten mins turn the engine on and off and this turns the fans off. It has run my battery out at least 3 times.

Damn............ It didn't occur to me that this is another symptom.

Thanks Armitage, I will now read your link.

Edited by Dynamic Dave on 25/05/2009 at 00:25

03 110, Anti Pollution System Fault light. - Driving Instructor
I am sooooooooooooooo much better informed but absolutely none the wiser.

I am reliably informed (peugeot dealer) that I DO NOT have a serium injector fitted.

Does this mean I should by a fuel additive and add it myself when I fill up?

3 times a week every week I travelled 75 miles out then travelled 75 miles back the journey always took about an hour. I did this up to the 105000 mile, then my baby learned to drive and I didn't have to do the journey any more.

This is pretty close to when the problems started???????????????

This thread has totally enlightened me, I am educated to the workings of my diesel engine.

The solution is to resume taking my baby to her club, take back some of her independence, sell her car because she won't need it any more and use the money to service mine because it is going to need it if it is going back on the motorways. The only problem I will have is a sulky teenager.

It is a DILEMMA!!!!!!!!!!!!!!!! SULKY TEENAGER??????????????? DODGY LIGHT ON CAR????????

I am going to settle for a dodgy light until some one gives me an alternative, so please people any advice will be gratefully received.
03 110, Anti Pollution System Fault light. - Armitage Shanks {p}
As I said I will report any results after my servicing on Tuesday. I do not have and never have had any warning lights. I have had the magentic sensor in the fuel cap replaced, to no great effect. I refuel my car once a month, almost empty to brim full but I still get the fans running = interrupted regeneration, about 3 times a week - only run for 10 minutes max so no flat battery.
03 110, Anti Pollution System Fault light. - Armitage Shanks {p}
Right, good news, for me. Car serviced today, no dreaded phone calls saying that I needed 4 new brake discs etc. The business of the cooling fan running on twice a week, when I park, was nothing to do with PDF re-generation, but was a faulty temp sensor which was telling the engine it was hotter than it actually was and thus trying to cool it when it was parked up.. Only faults in 5 years have been this sensor, the fuel cap magnet sensor (replaced), a broken passenger sun visor (warranty), and a failed dashboard digial display (warranty). No annual service has yet cost over £200, not including today's for which I haven't had the bill yet so I am well pleased, overall.

i believe this is the throttle position sensor/circuit
i replaced the throttle pedal in hope it would cure the problem but no luck. the light still came up and the power is still intermittent.

i have spent an arm and a leg on this car and i really want it to start running properly. anyone had the same problem or have any idea how to fix it?

Hi everyone, really need some advice!!
Just hd 2003 307 HDI back from a diagnostic check due to antipolution fault message>loss of power>engine management light coming on then going off.

Mechanic said high pressure fuel filter fault £900 but can not confirm this will fix due to swarfing being found.
To fix this quoted me £4,500.

This is not an option, was he using scare tactics? if not how long do I have before it stops all together?

Car was fine before service and new back box put on by Kwik fit!!

Really appreciate any help/advice.
03 110, Anti Pollution System Fault light. - Armitage Shanks {p}
Sorry to read that. SFAIK, if the HP pump fails it has to replaced, obviously. However the swarf also can get into the rest of the system and this can cost you 4 injectors as well. That said, pumps and injectors can be refurbished, with a warranty. If you want a contact re the pump re-furb e mail me. I had a SAAB pump refurbed, with a 12 month warranty, for 1/2 the cost of a new one. You can find injector refurb services via Google or Yellow pages - good luck.

03 110, Anti Pollution System Fault light. - Armitage Shanks {p}
SFAIK you could take it to a garage, maybe Pug dealer is best, and get them to do a 'forced regeneration'- this will clear out the PFD comprehensively. I think this what you need as you say p1429 is there and I think it means the filter is clogged hence the pressure diff. This is an opinion and not a statement of fact - in the absence of the esteemed Screwloose who had ALL the gen on these diabolical systems!

1. PEF Filter at fault- will need diagnosis with a machine that can read PEF and Additive ECU parameters.

2. PEF Differential pressure sensor- water ingress common fault

3. Additive is Eloys 172 which is about £70. Counters must be reset.

4. Tank Cap Sensor Fault- Possible tank cap and associated wiring

5. Additive ECU faults-Removal and replacement of ECU can cure faults-if it does not than a new one is required

Was the garage you took it to a Peugeot main dealer? They tend to be the people with all the computer diagnosis equipment but sometimes seem to lack the expertise to interpret the diagnostic codes.
03 110, Anti Pollution System Fault light. - mrgenuine
no not a main dealer. I have a friend at a garage locally who plugs it in for free. he knows his stuff but cant work out where the problem originates from.
03 110, Anti Pollution System Fault light. - Armitage Shanks {p}
I am afraid that is why a main dealer is more likely to be able to fix the problem, at a price! Just hope that you local one is up to speed! Check out HJ's list of good garages in the top toolbar - there might be a recommended one near you.

Hi, had antipolution fault few times on and off. Went to peugeot in oldham paid £37 for diagnose (think that's a good price) and been told that it's a turbo fault that it kicks in in a wrong time blablabla...
Quoting their invoice:
Anti polution fault on vehicle. Carried out initial diag test and faund 1 perm and 1 interm fault stored.
Turbo position Repeat signal too distant
EGR Valve circuit position tooo distant.
Requires further inverstigation.
Anybody (please screwloose) know what that might be they want £285 for taking it to bits to see what it might be.

i own a 53 plate 307 2.0hdi(110), the other day an "antipolution warning" message can up in the display and the engine management light on the dash came on, no power loss, nothing happened(as yet) car drives as normal.
had the car diagnostic checked at my local pug service center(cost me £80) and came up with the following codes(sorry no actual code numbers as they were not on the bit of paper the garage gave me).

intermittent fault. control unit. internal microprocessor fault
intermittent fault. control unit. internal microprocessor fault
intermittent fault. control unit. internal microprocessor fault
intermittent fault. sensor supply. short circuit to positive.
intermittent fault. diesel pressure signal. supply short circuited to positive of to earth
intermittent fault. accelerator pedal signal 1. supply short circuited to positive of to earth
intermittent fault. accelerator pedal signal 2. supply short circuited to positive of to earth
intermittent fault. turbo pressure signal. supply short circuited to positive of to earth
intermittent fault. analogue/digital conversion of signal accelerator pedal. internal fault in the ecu.

now i read that you might need codes from the ecu. something like RHS BOSCH EDC15C2
if this makes sense to you could you please help as its confused me.

thanks

After reading this I'm sooooooo glad I don't have a Peugeot any more.

For one example, after the gearbox was replaced on my 3-year-old 406HDi 90, the remote central locking ceased to work. The key battery was fine, the problem was that the car had "unlearned" the remote activation function. Peugeot wanted £78 to reprogramme it to work correctly - I simply used the key in the door for the next 6 months until the car spontaneously combusted and relieved me of the problem.

she as had this car from new .well she was on the way home from work when the car started running really bad if this was a petrol car u would say its the leads or plugs

with this we put the car into a garage where they told us it was the egr unit .we told them to fit this and 1 week later they called us to say the egr unit did not work so they put the old one back on .so over the next 3 weeks they played with the car and could not fix it .they then sent the car to the dealers so they could sort it .the dealer also said it was the Egr unit and air flow unit so we told them to do it .

well 2 weeks later the dealer called to say the car is still the same and we may need a new engine .they say the car is fine when hot but as trouble when cold and still running bad .this as been going on since the 14th july can someone please help .

I've had this problem on my 307 twice now. One at around 50000, and now again at 148000. Fault description was unblock blocked filter. I removed the particulate filter (DPF) and replaced with another, with new particulate temperature sensor, but the fault remained so I swapped back to the original parts. I then took the car to charters aldershot (peugeot main dealer) for a diagnostic check costing £48. Diagnosis was 5 x possible faults, which would require a further 2 hours investigation at £80 + vat an hour!!. The result of the investigation was a faulty exaust DPF(Diesel Particulate filter) pressure sensor. Which gave me a final bill of £249 which was pretty good I think after listening to some of the horror stories on here which sent me totally the wrong way to diagnose the problem. If you want to replace the pressure sensor yourself, you need to take out the battery and the battery tray (which takes about 15 mins) and the pressure sensor sits just under the master cylinder. The sensor measures high and low pressure difference from the particulate filter. You must make sure that you refit the two pipes the correct way round when you refit the new one.

To be fair I won't be going back to puegeot as long as there is breath in my body. But just wondering if your car had a history of cack starting and blowing a bit of smoke when cold? As mine has just died on me, then cured itself IT'S A MIRACLE!!

03 110, Anti Pollution System Fault light. - buddyell

Best thing I ever did was get rid of my 307 110, complete pain in the neck.

I used to find that if it went into limp mode, normally in the worst place possible, if I stopped the car and opened the fuel filler cap the light would go out and all be would be ok for a while.

FAP fluid I topped up myself, although you still have to pay Peugeot to reset the level (otherwise the car doesn't know how much is in the FAP tank). I had the EGR valve changed, which highlighted a split in the turbo pipe, cheap enough fix for both. All was well for a while and it started all over again. Regen is basically a run for 20mins at above 3000rpm, which kicks off the overheat chain in the cat, all well and good it your not stuck in Limp at 2500.

One thing I was told (but had lost interest by this point), was that there is a switch in the filler neck, so every time you fill up FAP fluid is injected into the system, the service guy I spoke too said that on some of the early 110's this switch had been known as a fault and as a result the switch was modified by Peugeot. Be warned this wasn't a cheap part and also a faff to fit (hence why I didn't bother).

HELP.....

Today my engine management light came on and the anti pollution warning came up on the screen.

I fueled the car on normal shell diesel yesterday, I had let the fuel mileage drop to 46 miles left, put £20 worth of diesel in.

Had the exhaust middle section changed last month, had no problems when changed tho.

It's a 307sw, 2.0 diesel. 117,455 miles on clock, due for next service in 1150 miles.

any advice on what I should do? the cars starts ok, drives in first ok, when I drop it into 2nd, it pulls, no power, then it kicks in and goes as normal.

hope this helps with a diganostic.

Thanks

Chris
