Peugeot 407 diesel 2.0 - Just bought 2H diesel -- thick white smoke - peugeot_buyer

All,

I bought a Peugeot 407 HDi 2.0 estate from an independent car dealer 2 days ago. It's 8 years old with FSH and only 42k on the clock.

Car was fine when I test drove it. I did notice the engine was warm when I inspected it (before I test drove it!), but otherwise everything seemed fine so I bought it. MOT was only 2 months ago. Later that day I drove it again and all was fine. I put about 40 miles on it in total.

Yesterday, I had real trouble starting it. I finally got it started, but engine didn't sound happy, and the car was shaking a bit. Thick white smoke was coming out of the exhaust. (Definitely smoke, not steam -- or maybe both, for all I know.) I turned it off after a few seconds as my kids were in the car.

Phoned dealer, who told me that this was common with diesels, and to run it for a few minutes. I was sceptical, but did so anyway. Continued to pour thick white smoke out of the exhaust for several minutes.

Today, the same thing happened. I phoned him again. He says again this is common with diesels, and suggests I change the battery!

I know nothing about diesels having never owned one. But white smoke has nothing to do with a weak battery, does it? Can someone confirm this before I talk to him (or write to him) again? I'm obviously reluctant to drive the car unneccessarily in this state to warm it up, which is what he suggests.

Next step would be to demand he diagnoses and repairs it (or pays for someone else to do so)? Sale of Goods Act seems to be on my side here. I paid nearly 5k for it, so it shouldn't be doing this.

Many thanks in advance for any help.

Regards

It sounds like the engine's glow plugs are faulty, which is why it was hard to start from cold. Thick white smoke on start-up indicates unburnt diesel fuel, it will clear when the engine is fully warm.

This is probably why the engine was warmed up when you test drove it. Go back to him and say the glow plugs are faulty, fault present at time of purchase, Sale of Goods Act, he needs to fix them or refund your money, etc.

Glow plugs can and do fail after years of use, but you shouldn't have to pay for them to be fixed in your situation. It could also be a fault with the wiring to the glow plugs, as this has to carry a lot of electrical power. The only way to tell is to have some diagnostic testing done.

(The glow plugs are an electrical component in the cylinders of the engine, which get red hot in a couple of seconds when you turn the key to start the engine from cold, to heat up the cylinder and enable more complete combustion of the diesel fuel).

I would have said the same if this was an old school Diesel engine, but even if all the plugs were shot i wouldn't expect the clouds of white smoke our OP is experiencing for quite as long as it sounds.

Peugeot 407 diesel 2.0 - Just bought 2H diesel -- thick white smoke - dieselnut

I would agree with GB.

The dealer had warmed the engine as he knew there was a problem with it.

The problem could be a number of things all of which will probably be quite expensive to fix. It's possibly down on compression on one or more cylinders.

Take it back & get a refund.

Peugeot 407 diesel 2.0 - Just bought 2H diesel -- thick white smoke - Bromptonaut

Incomplete combustion is causing the smoke. The question is what is causing the combustion to be incomplete.

On a modern direct injection engine, or even on old IDI, I'd not expect a faulty plug to cause more than a bit of hesitation and a little bit of smoke at current daytime temperatures. Compression is certianly one possibiity, injector faults, HP pump/common rail pressure or injection timing are a few others.

If it were mine I'd seriously consider rejecting it. Alternatively take it to a Pug franchise or (better) a decent diesel specialist and get it properly diagnosed.

Are you sure all the warning lights are working - some of the possible faults should bring on the engine management/emision control fault light on the dash. .

Peugeot 407 diesel 2.0 - Just bought 2H diesel -- thick white smoke - peugeot_buyer

Thanks all for the quick replies.

Given what has been said, I'd rather just take it back for a refund than mess around with trying to get it fixed.

Looking at this: www.honestjohn.co.uk/faq/consumer-rights/ , it looks as though I can do this. Not sure if he gets three strikes, though? (Bernstein v Palmerston Motors 1987)

(Edit: no lights on the dashboard. No indication anywhere that anything is wrong.)

I know I am fascinated by DPF's but is it possible your car is trying to re gen?

Peugeot 407 diesel 2.0 - Just bought 2H diesel -- thick white smoke - Avant

I don't think regeneration would make the car difficult to start, would it?

Peugeot 407 diesel 2.0 - Just bought 2H diesel -- thick white smoke - skidpan

There are many factors that need to be met before a regen will start. One of those is the engine must be at a certain temperature. That means several miles of motoring before a car will attempt a regen.

Peugeot 407 diesel 2.0 - Just bought 2H diesel -- thick white smoke - 72 dudes

Reject the car - too many variables to allow the dealer to try and put it right. As you only bought it on the 15th, strike while the iron's hot.

The fact that he told you twice that this is normal for a diesel and to change the battery, suggets he knows there is a fault.

Please come back and tell us what happens.

Peugeot 407 diesel 2.0 - Just bought 2H diesel -- thick white smoke - peugeot_buyer

Thanks for the reply.

I emailed him yesterday after my OP, telling him I rejected the car, and that I wanted a full refund, and giving reasons. He replied within an hour, saying, basically, p*** off, you have no mechanical knowledge, the car is fit for purpose, and fit a new battery. If it's still bad after you fit a new battery, he will get a qualified engineer to look at it.

I have been keeping records of what's happening from the moment the car went wrong (including phone calls, etc). I have video evidence too, and my neighbour saw what happened on the morning following the purchase.

I'm spitting blood about this, but trying to keep it cool. Don't want to waste time and money getting a mechanic to look at it (and my neighbour worked with diesels for decades, who agrees largely with what has been written above, and that, whatever is wrong, it will be expensive).

Advice for next step, please?

Thanks again.

I suggest a letter, post by mail which requires a signature. Again outline for your reasons for rejection. Don't go beyond facts and try and keep emotion out of it.

Someone with better legal knowledge than me will hopefully be along, but in your letter you should advise him that if he does not respond within say 5 working days with reasons why he thinks the car was NOT faulty on the day of purchase, you will commence legal action under the Sale of Goods Act - the car is neither fit for purpose nor of satisfactory quality, given age, mileage, price etc.

Then you need to file a small claims court proceeding. Search online for this, it will cost you a few hundred IIRC and even if you win, the dealer may be reluctant to pay up.

However, his attitude stinks (from what you've said here) so he will try and avoid facing his responsibility For every 10 people who experience this kind of treatment, I suspect he knows that 8 or 9 will just go away. Good luck.

Peugeot 407 diesel 2.0 - Just bought 2H diesel -- thick white smoke - gordonbennet

I agree with 72 dudes view of this, its quite obvious the dealer is a wide boy, don't bother with spoken contact, he's probably an expert at waffle and will attempt to prolong things to make things more difficult for rejection.

Get legal immediately, his attitude is all the reason you need, he isn't going to do the decent thing and behave honourably, he wants it the hard way let him have it.

If it were me i know it will cost more for me but i'd let my solicitor sort him out, it might cost more but he sounds like he needs a legal nose bleed, but then i don't trust meself to do the small claims route well enough.

Peugeot 407 diesel 2.0 - Just bought 2H diesel -- thick white smoke - pd

The problem with using the small claims court is that it is, by it's own admission, hopelessly behind and collapsing under it's own weight.

They're doubling the fees this month in an attempt to stop people using it as the average time for a very simple case is currently 7-8 months before a hearing and the general policy is to try and force you into mediation.

I'd agree with the general diagnosis of the car - it is the poor starting which is the root cause. Diesel do sometimes puff out a bit of smoke when starting on a cold morning but this time of year it should fire up promptly and cleanly. The smoke you are seeing is partially burnt fuel coming out as it attempts to fire on some cylinders. This can *sometimes* be due to an iffy battery - if the engine doesn't turn over fast enough the pressure in the common rail doesn't build and it won't fire. Modern diesels do indeed need a very healthy battery. If you have another car it would be worth trying jumping to it and seeing if it helps to rule this out.

The engine in these is fairly common and used in various PSA, Volvo & Ford cars so a diesel specialist should be able to diagnose it (which you'll need to do if going to court).

The seller clearly knew there was something wrong with it.

Is there any reason why mediation (or some other form of alternative/proportionate dispute resolution) is necessarily a bad thing?

As I understand you cannot reject it until the dealer has two tries at reairing it,more than likely the EGR valve requires cleaning or replacing common fault.

All,

I've arranged for a third-party specialist inspection and report. I will let you know how it goes.

Meanwhile, others in the same situation may find this useful: OFT guidance for used card dealers. (Apologies if you already know about it.)

The second part, which covers SOGA, is more useful than the first (though that also seems to be relevant to my situation, as I reckon he's breached several CPRs). A good summary.

I've only just seen this thread, so apologies for coming late to it. The 2L 407 is regarded as the most reliable of the range.

While old batteries do cause some strange things to happen, you shouldn't be seeing any white smoke and what the dealer has said is wrong.

The age and the low mileage would make me think that the problems might be concentrated on the DPF and regeneration system. The 407 is a "rep car" and designed to spend its life on motorways. Lots of short trips will have shortened the life of the system.

A good diagnostic check (I'd recommend your inspectors use Planet or Diagbox) will show up any faults and can check individual components.

Keep us posted as to what happens.

What on earth was the point of that comment, Collos? If you haven't anything helpful or constructive to say when someone has a problem, don't say anything at all.

Peugeot 407 diesel 2.0 - Just bought 2H diesel -- thick white smoke - Hamsafar

Poor batteries do cause low crankspeed which can make starting difficult and as diesel is being injected, when it finally builds up enough heat through semi-conbustion and friction to start it will clatter and knock and puff white smoke.

Heading back on track with the OP's question :-)

There could be a possibility of the EGR cooler having an internal leak ? Have you noticed if the coolant level has dropped any ?

I had one giving the symptoms of a head gasket leak a year ago, the gasket checked out OK, but the EGR cooler had failed internally and was leaking coolant into the cylinders leading to white smoke from the exhaust as it burnt it off.

Half the problem with modern diesels is people not being able to fix then due to lack of proper knowledge and/or not having the correct tools.

Having proper main dealer level diagniostic software for any car isn't guaranteed to fix anything but it certainly helps and is often a lot better than generic code readers.

Even the good stuff (e.g. SnapOn Solus with recent firmware) often can't pick up things which specific manufacturer kit can.

Even the good stuff (e.g. SnapOn Solus with recent firmware) often can't pick up things which specific manufacturer kit can.

Even then, it's not infallible - last year a Volvo main dealer took three attempts to fix a recurring 'emissions warning' lamp in my V60. The error code that kept coming up was "EGR flow out of range."

When I first took the car to them, I told them the fault had come up while the DPF was regenerating, but the fault code was EGR-related, so they put on a new EGR valve, some pipework etc ... and the fault kept recurring.

Eventually they resorted to robbing parts from another car and testing by substitution. Turned out to be a dodgy DPF pressure sensor. But the Volvo diagnostic list has no DPF-specific fault codes, which seems to be utter madness, but its true.

So the main dealer spent a good couple of days diagnostic time, and fitting new parts, chasing a red herring. I reckon the total cost would have been well over £2000 if the car hadn't been under warranty.

And so another good reason not to buy any diesel outside warranty.

Would the volvo dealer have swapped bits from "stock" cars if the customer was paying.

Once the bit is fitted invoiced to customer!

I agree, if I was in the market for a private car, this experience would certainly make me choose petrol, not diesel.

I understand that dealers doing warranty work have to follow diagnostic procedures laid down by the manufacturer's head office. But when the Volvo first went into the dealer's workshop with the fault, I gave the service manager full, written details of the circumstances under which the light came on (stating the DPF was regenerating at the time, and the regeneration stopped the instant the warning lamp lit up).

Yet they only looked at the DPF and its sensors after they'd replaced everything in and around the EGR valve. Their loss, not mine in this case (I had a courtesy car etc), but I would counsel anyone buying a DPF-equipped used car to consider an aftermarket warranty that covers DPF sensors (if such a warranty exists, that is).

Peugeot 407 diesel 2.0 - Just bought 2H diesel -- thick white smoke - Avant

It's this sort of example which has convinced many of us, including HJ, that the days of diesels holding their value better than petrols are coming to an end.

I would go so far as to say 'don't buy a diesel if you're going to keep the car beyond the warranty period' unless the diesel is one with a good record for lasting well without expensive failure. The VAG 1.9 PD and Ford 2.0 TDCI are two such, and I think one or more of the Peugeot/Citroen engines - I can't remember which ones.

So why do the dealers use the same equipment then?

Its more than a code reader, it reads live engine data and also can test individual parts, such as opening and closing the EGR valve and tells you what %age its open and operating at.

You sound like you own one of those garages where you just throw parts at a problem at the customer's expense. Nice but of profit in fitting an EGR valve (although there's no evidence this is at fault on this thread). I bet you hate that there are people out there doing diagnostics and taking your nice lucrative business away from you! Either that or you're just an armchair expert. My credentials are detailed below, maybe you'd like to share yours.

And I've never said "If its not in planet then it cannot be fixed" so I don't know where you've got that from. I recommend Planet simply because of rip off or irgnorant fix-anything (or try to) garages who use any old code reader and have no life experience with Peugeots (unlike me who has been working with and owning and driving them since 1992) and just waste the owner's time and money with bad diagnostics -

Such as the two garages who claimed the high pressure fuel pump had failed because the fault code pointed to that - P1113. My long experience with Peugeots told me it was probably the lift pump. A diagnostic with Planet showed that the fuel flow at the pump was below reference value.

The main problem with modern diesels, and modern cars in general, is that the skills set required to fix them is lacking in many garages - including main dealers.

You do need the latest equipment but equally important you need to know how to use it and have experience in being able to identify what the fault actually is. As the above example illustrates - a code does not necessarily mean that it is that part at fault.

Far too many garages will spend on buying kit but then won't spend keeping it updated and their staff trained on it.

Peugeot 407 diesel 2.0 - Just bought 2H diesel -- thick white smoke - peugeot_buyer

Thanks again for the replies.

The main dealer started it from warm, and did a standard diagnostic test on it, which didn't reveal anything. I suggested they keep it overnight. The next morning, they started it, and found white and blue smoke, and the following faults:

- EGR valve was stuck closed
- Engine was mis-firing from cold
- Exhaust fumes were entering the interior (!)
- A minor fault with the air con.

They quoted me about £850 to fix the EGR and run further tests on the mis-firing (compression and injector fuel leak-off tests). This didn't include tests on the exhaust leak.

I think I've got a strong case for a refund.

The EGR valve stuck closed doesn't sound like it would be the issue to me, have a look on the Pug forums and see how many people have blanked off their EGR valves, or disconnected the vacuum pipe when the valve is in the closed position (myself included) and we don't have any smoking problems.

There have been many very helpful posts appreciated by the OP. The spell with a few negative exchanges was totally unnecessary and rightly picked up by moderator.

I have previously used the forum under a different username but dropped out when some threads were becoming offensive. I returned because I do value and benefit from people willing to give their time to benefit others.

There are many very knowledgeable and helpful people who contribute. When threads are affected by snide comments it erodes the fundamental value of a forum.

Very good news. If you liked the 407 you could consider the petrol model, from my experience its less troublesome that the diesel equivalent. The only downside is its heavy and drinks fuel and costs a fortune to tax.
