Well I got in my A6 2.7t today and started it up. The next thing I know I am in a cloud of smoke! The car ran fine the day before. It seemed to be lacking some power but did not throw any codes and the engine is still running smooth. So am I safe to say that I have a couple of turbos with bad seals? Or are there any other guesses. No I have not done a compression test yet. Thanks guys.
Well last night I changed the oil and went with 5w30. This morning it was well below 0 started the car and guess what. No smoke. Not sure what happened but the car is running great.
audi recommends 10w-30 for every weather condition....but i would stay with the 5w specially during the winter....and yes the s4 does it and then all the boost burns it off!!!!! woooohoooooo!!!!!
