3.0 BiTdi smoke on start up ?

[OolongA7]

Any one think this amount of very smelly smoke on start up is acceptable ? 2017 and 39,000 miles

This is after standing overnight. Once up to temperature it doesn't smoke but there is a strong smell of diesel / burning oil at the rear of the car.

Just in case the other link doesn't work.

It's not a trick question.

That doesn't look good to me. I've just sold a 2014 BiTDI with 48000 miles on the clock which did lots of short runs and thus many many cold starts and it never had any hint of smoke no matter how long it stood.

Thanks for the comment, yes indeed obviously a problem somewhere. It was an Approved Used car and thankfully still under warranty. It's at the dealer now, I really hope they don't try the "they all do that sir" approach.

Picked up the car yesterday afternoon, "it's all sorted, it's just a bit of smoke from the last DPF regeneration that happened 76 miles ago", they said.
Really ? ? ? Seriously ? ? ?
So, drove home, about 15 miles.
This morning, exactly the same smoke if not more on start up. Audi Assist come out to look, "that ain't right" he says, so it's back to the dealer.

 

[billgatese30]

Well at least you have the Audi Assist bloke on your side. Definitely doesn't sound right though! Hope they get it sorted.

That's a bit of a ridiculous excuse from them isn't it!!
Well at leas the Audi assist chap has given you some backing to have it back with Audi.

I have had some really odd explanations from Audi about various things which mechanically could never make sense, but when I've spoken to an Audi Technician, they are as baffled as I was about the explanation that the Audi 'service assistant'!

An update for those interested.
The car has been at the dealer I purchased this from for a month now. The car is still smoking as can be seen in this other video I made about 5 weeks after the first one.


I'm saying the engine is burning oil as the smoke is blue and it stinks of burning oil.
The dealer says it's not burning oil as the smoke is grey / white.
They say that they are not sure what the problem could be but they think it may be Injectors.
O.K. so I ask what are they going to do about it as I bought the car as an Approved Used Vehicle with Audi 12 month Warranty.
They say that the Audi Warranty company will not authorise them to replace the Injectors as they cannot prove that the Injectors are faulty.
They tell me that the Audi Technical department (in Germany !) have no idea what the problem could be ! Really ?

My suggestion of valve guide / seal issues has been dismissed as poppycock.

I first highlighted this issue on April 18th. I think it's time to involve Trading Standards and the Motor Ombudsman, otherwise this will just go on.

 

[billgatese30]

100% something wrong with that in my opinion. The fact it clears quickly possibly does suggest oil collecting due to valve stem seals or similar, however difficult to prove. It is their issue though so if they aren't going to attempt a fix under warranty I'd be onto trading standards for advice otherwise Audi may attempt to fob you off until the warranty expires and then they'll make it your problem and not theirs.

I gave Audi UK Customer Services a call yesterday. The person I spoke to was quite sympathetic with regard to what has happened. She agreed that the time frame was rather excessive and has set up a case file for someone to look at and get back to me within 48 hours. I asked the question "what happens when the warranty runs out , in 7 weeks". She assured me that any issues raised within the warranty period will be dealt with. I wish I had that in writing.

Please keep us updated

 

[OolongA7]

Well now, it appears that your Audi Approved Used Car warranty isn't worth the paper it's printed on when it comes to Fuel Injector faults.

Probably worth nothing for a lot of other faults too.

So, as this farce has been going on for three and a half months now the dealer and Audi customer services have agreed to replace the Fuel Injectors as a gesture of goodwill. I'm told that normally the customer would be required to make a contribution to the cost but on this occasion as this issue has been going on for so long my contribution will be waived.

 

[Dj219957]

Interesting. Please let us know if new injectors fixes it.

 

[Dj219957]

Do they suspect one is leaking when the car is off or something?

I think you're "My suggestion of valve guide / seal issues" is correct.
It's typical of an engine left standing overnight, an inlet valve seal going cold, shrinking and leaking oil onto the valve seat. On start up the oil is drawn into the combustion chamber and burnt i.e., blue smoke out of the exhaust. As soon as the valve seal 'warms,' and that doesn't take long, the seal seals and end-of the 'blue' smoke. Of course, if you've blue smoke under-load then that'll be a different cause, but yours I agree will be an inlet valve seal.

If injectors it would be 'black' unburnt fuel smoke and I doubt would go away after start-up.

 

[Dj219957]

Any update please?

 

[OolongA7]

I was told that the car was being transferred to another Audi dealer on the 8th of August to have the injectors replaced as the dealer I bought the car from were too busy to do the work.

I've heard nothing since.
I'll be giving the Audi Customer Service guy a call this morning for an update.

Changing 6 injectors should be a straight forward job, maybe they've had a problem along the way and broke something ? ?

 

[Dj219957]

Thanks for the update. Perhaps they have changed the injectors and its still doing it but don't want to say anything yet. Or like you say they have ran in to a problem.

 

[OolongA7]

Decided to call the workshop direct rather than speak to the Customer Services rep.
Nothing has been done to the car as they are really busy.

It would appear that my car still has zero priority even with the involvement of Audi Customer Services.

The novelty of driving the Q5 50 TFSIe courtesy car has now worn off. And it drinks fuel at a faster rate than the Bi Turbo !

 

[OolongA7]

So, the 6 injectors were replaced on Monday, the dealership that did the work were happy that the issue had been sorted.

Tuesday the car was then driven some 40 miles back to my usual dealer so that they could park it up and then check the following morning that all was well. I asked them to do this. They tell me Wednesday that everything is good.

Before I collect the car I ask if they can put the car through an M.O.T. as it is due.
The M.O.T. was done Friday, it passed and we agree that I will collect the car Saturday morning.

Saturday morning I get a call, "Sorry, but we have just checked you car and there was some smoke and a nasty oily / diesel smell from the exhaust on start up, which may be a result of having the M.O.T. done on Friday. Can we keep the car till Tuesday so the workshop can check it over ?".

" may be the result of having the M.O.T. done " ? ? ?

Starting to get tedious.

P L E A S E: it is just NOT injectors: #15 above

 

[Nomakbg]

Hello,

i have similar problem at the moment.

Smoke is more blue i think and it happens in the morning until the car gets to temp. Has the injectors change done anything to you ? Or problem continues to occur?

 

[OolongA7]

I popped into the dealership late last week to take a look at the car myself. Unfortunately new injectors have not sorted the issue.
I have now asked about a refund.

Oh my, now that's a surprise!

 

[Nomakbg]

Still smoking? Have you tried with engine covers, or in particular the ones on the valves? Could be oil building up when you shut the car off and then when you start it it burns it, leaking through the valves where there is rubber gasket or cover, do not know how it is called.

 

[OolongA7]

I believe the only work done to the car with regard to the fault is replacement of 6 fuel injectors.
I am in the process of rejecting the car as I feel like this could go on for a long time.

 

[Nomakbg]

Mine has similar problem, waiting change as well and i am going to report if any difference or problem is fixed.

 

[Nomakbg]

So update from today, injectors are good and as in your case it turned out not to be the problem. Unfortunately i will have to dig deep in this case in order to see what the issue is because I have no idea on selling the car.

 

[OolongA7]

The A7 has now sadly gone, we came to an agreement on what price the dealership would offer me against another car. Basically they used a £0.65p per mile depreciation factor which I guess is about right. As the workshop didn't know what to try next to solve the issues and the Audi Warranty Dept. were being very difficult in authorizing any work I thought it best to get rid.
Driving their Q5 50 TFSIe courtesy car around for 9 weeks made my wife want one, so we now have a Q5 S line 40 TDI Quattro.

 

[billgatese30]

Glad you got sorted in the end even if it meant another car and hopefully you weren't too out of profit!

 

[OolongA7]

Yes, I'm glad this problem has been resolved. After 10 months I thought the dealership would put up a fight but it went quite smoothly in the end. The 3.0 litre Biturbo is a great engine unfortunately I bought a lemon.
It would have been nice to get to the bottom of this problem.

So I'm not the only one to move over from E30Zone to Audi then? Greetings, Ole Boy!
