Hi, My dads 2002 B6 Audi A4 (1.6) is mysteriously loosing about 1 litre of oil every 1000-1200 miles. He has had it checked by the audi dealer and shown no problems. No leaks, no abnormal emissions showing burning oil...nothing!! I read another thread saying that these engines can drink oil sometimes but surely that is excessive for such a short amount of miles??? The car is in perfect working order by the way! Cheers, Tom.
