Problems with Audi 2.0Tdi BRE engine. urgent help needed

[craig2210]

Hey guys,
Im looking for some urgent advice. My wife was driving home yesterday when she heard a pop! She thought she had a blowout and so got out and checked around the car, but all was ok.

She started the engine and went to drive off when the car started kangarooing and then white smoke came out the back. She stopped immediately and the called the recovery people who brought her home.

I checked over the car when I got in from work and I have the following symptoms:
Car seems to run OK at idle
Rev the car to 1500rpm and start hearing a slight splutter which gets slowly worse
Rev a bit higher when all hell breaks loose. Car starts to violently misfire and a load of thick white smoke comes out the back and I noticed some smoke being released from around the engine but can not pin point where
Car will not drive under load. Tried pulling it onto our drive (slightly uphill) but just splutters and has no power
This all happened 5mins after filling up with diesel (definitely was diesel,I checked the receipt ) however this could simply be coincidence and I don't want to be led up the garden path thinking diesel contamination when it could be something a lot worse.


I have got two days off work starting from tomorrow, as we really need to get the car back on the road as it's our only car and we live out in the country so any help would be much appreciated and I thank you in advance.

Sounds like a boost hose has split/come off.

That sounds a lot like what happened when I filled my diesel van with petrol, although I ran it for much longer. It may be worth checking.

Well that's exactly what I thought when my wife called me, especially considering it all happened after she filled up but I've checked the receipt again this morning and it definitely says diesel on there. Possible crap diesel for the garage? Anyone have any other ideas? The car did suffer from oil pump failure a year ago. Could it be related to this and can anyone point me in the right direction of what to check for?

I also thought I had filled with Diesel - I have a fuel card which is only valid for diesel - and on checking the last fill with the card suppliers, diesel was recorded. It later transpired that a delivery driver had put petrol into the diesel tank and the garage had 7 claims against them. I got a new (reconditioned) engine via their insurance.

Apparently most (maybe all?) major garages now have sensors for this, so I don't know if it's still possible. The garage where I did it was a small garage in our village (they still come and fill the car for you) and it was about 15 years ago.
