Hello,
recently I purchased Audi 2004 A3 with 2.0 TDI 140 engine and I'm having a blue smoke issue with it.
Engine starts nicely when cold or warm and there is no smoke at startup at all.
It pulls nicely and I don't have any fuel consumption or performance issues
However, when it's hot and idling, when I pull away from idle, it puffs some blue smoke for a second and then it clears away. No smoke at idle either, only if I rev it from idle or hard accelerate from standing, then it puffs some blue smoke on take off and disappears. If I rev it again after that, everything is normal and there is no smoke... Leave it idling for a few secs and rev it again and it puffs blue smoke again.
I know that blue smoke means that engine is burning some oil but I've checked the oil levels and they are fine
Could it be bad fuel maybe ???
Do you have any suggestions what could be the cause for this ?
I am new to forums so apologies if I have missed some thing thank you in advance
