(2000-) 2.2 HDi, unable to clear ecu fault codes - Ade607
I have a 2.2 HDi pug 607 that is in serious danger of being pushed off a cliff, if any one can advise how to get this sorted it would be much appreciated.

Took it to garage and had everything cleared as the car was in perminent limp mode and I could not clear it with my ELM323 reader,

it was showing an overboost on the Turbo plus more errors but the car was working again and just tripping into limp mode when the turbo overboosted but fine again after turning the ignition on and off.

I took the turbo off and decoked it, put it all back together but the car went back into perminent limp mode so took it in to have the ECU cleared down again. Now the garage can't clear the errors and I am getting a headache, they have given me a list though!

I have got P1447 - differential sensor pressure too high
P1429 - differential pressure signal low
(is there a right way around for the two pressure pipes on the fap or should this not matter?)

P1421 - EGT Sensor (no idea what or where this is or what may be wrong with it!!)

P1519 - Engine Oil Sensor Malfunction (no idea where this is?)

P0245 - Turbo pressure control (I think this could be the over boost problem still ???)

P0380. Glow Plug/Heater Circuit "A" Malfunction

And irritatingly as I just bought a new one P0100 MAF sensor signal too high.

Arrggghhh, any advice that doesn't involve taking the thing to peugeot (that's my last resort at £80 per hour) would be greatly appreciated.

2.2 HDi, aaarrrggghhh, please help - Ade607
Sorry, one thing I forgot! does anyone (in the world) have a picture or diagram for the three vacuum solenoids at the back of the engine as I can't find one anywhere, I just want to double check they are all going to and from the right place as it looks like one of these (I thinks it's the EGR one) seems to go to two diaphragms with no vacuum, surely that can't be right??

I can't see any way of answering that in under 2,000 words and I don't have that amount of time. There are no quick ways of explaining all the various systems and you are so, so, far adrift.
2.2 HDi, aaarrrggghhh, please help - Ade607
Really should have stuck with my old spitfire, nice and simple, basically my car doesn't work because the bits that stop it choking fluffy bunnies and flowers aren't working properly, that's really irritating, it's not like I even like fluffy bunnies unless they are on my plate with gravy.

I think these new super green cars should have a big bunny killer button that switches it back to a good old fashioned smoke ridden diesel, I'll even off set my carbon by eating more cows to reduce methane emissions (win win).

Does anyone know if there are any manuals available for this engine anywhere, I have looked everywhere, searched google etc. etc., I had assumed there would be a Haynes for the C5 at least but no. The best I have managed to find so far is a parts catalogue with exploded diagrams but not very helpfully.

Just a few code definitions.

P0100 - MAF - circuit malfunction. [P0103 is signal too high.]

P0245 - Turbo wastegate regulating valve - circuit low. [An electrical issue.]

P0380 - you've got that one. [Got at least one glow-plug out.]

P1421 - Catalyst damaged. [Whoops...]

P1429 - Differential pressure sensor value. Coherence of the sensor when engine stopped. [Check readings in live data.]

P1447 - Particle filter pierced or differential pressure incorrect. [As above.]

Are all this lot active codes; or stored from an unplugging spree? If that lot are current, you've got £1500-worth there.
(2000-) 2.2 HDi, unable to clear ecu fault codes - Ade607
Well that's annoying, the definitions came from the 'diesel specialist' that tried to clear the codes down for me, I thought they were different from the generic defs I had found but assumed this was a pug thing.

Just one question 'Catalyst damaged', does this refer to the FAP or the rear cat?

Now luckily it came to me last night, I think I know what may be causing P1447 & P1429 as the pipe that connects the rubber house to the FAP has become (or always is) very, very brittle and the end broke off so I had to fit the hose higher up. Hopefully the pipe's just cracked in another place higher up and is leaking pressure, didn't check this when I put it back together as I did it in a storm with no garage and the pipes a git to get to from underneath. Should explain these faults, fingers crossed . . .

P0245 would explain the over boost issue, may rewire the solenoid to see if this fixes both issues (if I can find a wiring diagram for this car that is!)

P0100, hmmmmm, I just replaced the MAF, not because of any errors, the cars done 100K and I was having problems so I thought it would probably need one by now, I think this may be faulty and will put the old one back on to test.

Glow plugs are probably due a change anyway . . . .

I am hoping this will cost the price of a bit of pipe and some glow plugs . . . . you never know your luck . . . .

PSA codes are indeed a pain - they are system specific. [Getting very hard to source now even the dealers aren't allowed lists.]

All that def says is "Catalyst damaged" - probably the after cat; but change both to be on the safe side and fit a new sensor and pipes while you're down there.....

Where did that MAF come from? If it wasn't the dealers, then it's likely one of the tens of thousands of total rubbish "Genuine Bosch" counterfeit ones sloshing around everywhere. These don't eat MAFs - put the OE one back on.
(2000-) 2.2 HDi, unable to clear ecu fault codes - Ade607
OK, had enough now, changed particle filter differential sensor and took back in to get a reset as if I can clear the filter errors it will work OK and I can then look at the other probs . . . most errors have gone but now being told I am showing a fault with the Particulate filter ECU . . .

Anyone got a sledge hammer

The particulate filter ECU?? Fault??
(2000-) 2.2 HDi, unable to clear ecu fault codes - Ade607
?? apparently it's got a separate ecu for the particulate system ?? I am working back in the south east from next week (actually earning money unlike cornwall) so I think it's going to have to go to puegeot . . .
(2000-) 2.2 HDi, unable to clear ecu fault codes - Screwloose

It's got an diesel additive ECU; but a particulate filter one is new on me. What was the code?
(2000-) 2.2 HDi, unable to clear ecu fault codes - Ade607
That makes far more sense, they said it was the ECU for the particulate filter system, it's reporting some errors to do with the fluid cap being missing !!! It's also reporting an internal error for the ECU apparently (no idea what the code is if there is one), must be the diesel additive ECU.
That would explain why I couldn't find any info on it at all . . . I'll look into this instead . . . hopefully nice and cheap (year right)
(2000-) 2.2 HDi, unable to clear ecu fault codes - Screwloose

Yes; that's the additive ECU. The cap sensor is highly significant; without it being in order, you can't even reset the fluid quantity.

Can't remember what a 607 uses; but have you lost any magnets from the cap - flap sensors are a common fail too.
(2000-) 2.2 HDi, unable to clear ecu fault codes - Ade607
Ah ha, once again things become clearer, the garage said the additive tank cap was showing as missing, I couldn't see any way it could possibly know that as its just a plastic cap and the tanks not pressurised as far as I know. The fuel filler cap however makes more sense. I do have the magnets on there, I will check the sensor is in place & doing something over the weekend.

I'm thinking the diesel specialists are not quite as up on these systems as the could be. Time to go to bite the bullet and go into pug for some proper diags (although I have heard the local pug dealer may not be any better!!)
2000 - Bosch ECU - Reprogramme To Ignore Faults? - Ade607
Hi, does anyone know if a bosch ECU can be reprogrammed to just ignore particular fault codes, if so how easy is this (I am an IT engineer and programmer so the technical side would be no prob if it's possible)??

I'll try not to laugh ;)


It is possible but is non-trivial. The old/simple ones I've looked at are bad enough. Multiple checksums. How's your assembler? On what processors?
(2000-) 2.2 HDi, unable to clear ecu fault codes - Frank01
Not a mechanic but I own a 607 and a similar problem. The vacum hoses that comes out of the EGR unit can come loose. It is under the bonnet at the very back of the engine under the drivers windscreen. You can see the pipes, they resemble the windscreen washer water pipes. Worth checking
(2000-) 2.2 HDi, unable to clear ecu fault codes - ferkemall

PSA are pigs on diagnostic because you need a Delphi scanner with the clip software and the scanner has to have a library for look up , after market scanners can't scan frog cars because they are not BI BIRECTIONAL so can't read all faults and certainly can't write to them to clear it .

Hope it helps I used to have a 607 never again !
