Hi, I have a 2006 A3 FWD 2.0 TIP. Yes, 120,000 miles but top engine rebuilt at 97,000 from cam follower wear issue. Car runs great otherwise. Mechanics at dealer accused me of chipping the engine cause it accelerates so well. Problem is on 2 occasions the car decided to blow white/blue smoke like a fog machine. I thought I blew a seal. Drove the 12 miles each time to the dealer and by time I got there, nothing. Diagnostics show nothing. Techs drove it to try and have it do it again and nothing. 1,000 miles separated the 2 incidents. On 2 nd occasion problem was really bad and my oil pressure light came on. I was 2 quarts low. I may have been a quart shy before but not 2. It normally is very good on oil after I had oil pump and balancers replaced at 87,000. I thought maybe transmission fluid getting into engine with the huge smoke trail, but the oil light is the key, I believe. The car is doin good right now but afraid to take it very far.

 

Your car is burning oil. Remove one of your turbo hoses and see if there is a lot of oil present in the hose. If there is then next remove ur valve cover and see if it is coming apart inside. The evap system is designed to run through the valve cover from the intake side to the turbo. Once the valve cover seperates oil starts getting sucked in and cause your oil burning concern.
