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.

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.

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. :)

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.

I think you're "My suggestion of valve guide / seal issues" is correct. :thumbs up:
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.
