Egr failure, particle filter, lamdba 2017 204

[Necessary Jago]

Help.
I purchased privately a 2017 plate 204 hp t6 with 128000 km on the clock 2 months ago.
It drank a litre of oil in 5000 km.
Then the coil warning light and particle filter along with limp mode nightmare on he motorway two days ago.
There's no pressure in the system. Gone to vw and they're saying new egr flush particle filter and replace lamdba. At a cost of €2392 to me.

Advice? Can I force them to flush it. Should I go elsewhere. Can't believe on a vehicle of this age this has happened and they say its all on you as it's out of guarantee.
I'm in France hence euros and km.
Thanks.

You are paying, it’s your choice. It’s the providers choice whether they do it or not.
If you are not happy take it elsewhere.
I’m no expert on DPFs but in my opinion there is no point in doing anything with the DPF until you fix the oil consumption issue.
From what I’ve read on this Forum flushing an EGR system is a short term measure.
I would be looking for a second opinion from a good independent VW specialist mechanic.

Ok you've got a 5 year old van with about 80K miles on the clock, I agree it's a problem you shouldn't have to deal with but you are where you are, like me you took a chance on a van with no warranty which saved you money on the day of purchase......
I agree with @DXX about trying a good independent VW specialist. You should also verify if the van has had a new cambelt / water pump / aux belt during its life, if not you need to get that done or things could get even worse.

The advice is much appreciated. Waiting on a specialist to get back to me. I knew I'd have to do the cam belt and water pump next year was recommended.
But I'm really f'd off, beyond belief that you have to factor in a new egr every 4 years. I mean that's nuts.

Keep the one that’s removed and clean / pressure test so you have a replacement to go in next time.

There's no pressure in the system.

Pressure - in what system? Have you lost coolant?

Pressure - in what system? Have you lost coolant?

It went very quickly through a garage just after it went into limp mode to check the errors and verify if it was safe to limp home. Errors were...
P029900 x2 régulation of pressure turbo
P20E00 scr nox
P223800 lambda sensor

In between then and it arriving at vw the particle filter light came on so I'm presuming there is a new error there also.

VW say that the lambda and particle filter need flushing and changing due to the problem with the egr.

I thought immédiately that there is a small leak and therefor it's sucking in air somewhere. Leading to pressure loss. Pfff

P20E00 scr nox

A typo? Perhaps P20EE00 - this is a SCR NOx fault, and actually fixed by fairly recent engine software update. At the moment I would ignore this.

P223800 lambda sensor

The fault code doesn't necessarily imply faulty sensor (P2238=signal short to ground). More likely faulty wiring.

I have to admit that I don't understand how these faults would have anything to do with EGR, or DPF.

For the pressure loss - have you checked this --->

EGR flexi-pipe: Exhaust Fumes In Cab, Hissing From Engine Bay.

I seem to have what I initially thought was an exhaust leak, but after further investigation sounds more like an air leak round the right rear back side of the engine. I wouldn't ordinarily be concerned and just get it into VW to looked at. (It's actually the first issue I've ever had with my...

P0299 basically means... pressure loss... engine was unable to produce the boost ECU commanded. Most likely this fault put your van into limp mode.

Thanks for that. A bit confused tbh. I'm waiting to hear what If anything vw will do in terms of gesture. I don't expect anything but we'll see.
I'll take it to a Bosch vw spécialiste next week for a second opinion.

Thanks

As for the cam belt etc. One Vw dealership over here said it was fine until next year so 5 years.

As everything was to be be undertaken before the sale, I will query this and go back to the seller if five years was too long.

Ah, of course, in the UK the recommended interval is 4 years, on mainland Europe it's 5 years, so that's fine, nothing to worry about.

Update
After complaining that its not normal the VW concession got back today to say vw have offered to pay half of the egr cost. Parts and labour.

Given that they are saying it's that, that's caused the lambda and dpf to fail its still a joke but better than nothing.

I've sent an email back saying as much and asking what more they can do.

Weird cost run down but here it is for anyone interested.

I've had 1 transporter and 1 cali , on my 2rd egr and all replaced at my cost with mileage under 30k , transporters are utter overrated overpriced crap

2nd or 3rd? Clearly you think transporters are 2urds.
It does seem that these egr problems are not just chez vw. But I agree. It's not right and they should accept full responsibility.

 

[Necessary Jago]

So a
Few weeks down the line. The wrong part ordered and finally fitted. Dpf cleaned out. Still a problem. Still at the garage. Now they reckon the turbo has gone. They also reckon it was the turbo that had caused the egr to foul and the dpf to block and Landa to go.

I'm waiting to see what vw now say.
If the turbo has gone. What else do I need to be worried about possibly.

Common for this to happen?

End of my tether here.

 

[Broadside]

Turbos usually fail for a reason such as oil starvation so if you go the new turbo route make sure they establish if there is sufficient oil flow. If that root cause is not understood then you could end up replacing an expensive part that will then fail again in a short period of time.

Someone on here posted a YouTube video of a mechanic fixing a blown turbo on a Saab 9-3, he was very methodical and explained why you need to fix the cause and not just replace the part which has failed.

102PS with 2 Turbo Failures - was re-map to blame?

For anyone thinking about remapping a 204ps for more torque there are two different DMF’s installed, one for 450Nm max and another for 500Nm max. I read it the 204 has 1 type for 500nm and all others has the 2nd type for 450nm.

Thank you for the help.
Extremely useful.
Speaking to he garage today they diagnose soley using the computer. They do not know and won't search for the cause of the problem.
Waiting to hear back from them after VW come back with their quote.
After that I think it's time to move to an independent specialist. Even if its accross country.

 

[Necessary Jago]

The quote is revised to include replacing the Egr, lambda sensor and bi turbo at a cost of €5700. That's with VW's participation of 30% on parts and labour. Still no answer as to why this all happened.

My question now is should I go for a reconditioned turbo from Germany for €1000 and try and find a garage to fit it?
How big a job is replacing it?
I think first thing will be to get it elsewhere for a second look.
Bloody difficult when no one can recommend a decent garage and no independent vw spécialiste!

I’m still struggling to see why the garage has concluded that the turbochargers have ‘gone’, have you asked them how they reached this diagnosis?
In you first post you stated that ’there’s no pressure in the system’, which system?
You also stated ‘1L of oil in 5Km’ but no indication that the garage has done a compression test on all cylinders?
I might be old school but ‘diagnosis solely by computer‘ is probably a good indication of a bad choice of garage / mechanic.

If the garage is thinking that the oil has been lost into the induction from the turbochargers then the charge air cooler will be saturated in oil, something that should have been spotted early on.
A collapsed / heavily contaminated air filter can restrict induction air flow and increase differential pressure between the turbocharger oil feed and induction causing the oil to be pulled into the induction.
A worn cylinder bore / piston / rings will cause excessive oil consumption and cause excessive crankcase pressure which will act on the turbocharger oil drain and reduce the oil flow through the turbocharger bearings. Without adequate oil flow there is insufficient cooling and subsequent failure.
Assuming the turbochargers bearings have failed are not in pieces get them re-conditioned.
I think I would be looking for a different garage if I were in your position.
