Same thing. A friend of mine owned my A4 before me, and just before he sold it to me, he had a repair done (car consumed a lot of oil). A week later, the engine broke down, at about 95000 km running distance. Audi technicians couldn't exactly address the problem though. Brand new engine and voilą, oil consumtion seems to be at normal. This was a 1,8tfsi though, and as sad as it sounds, warranty was out only 2 months before the breakdown, so the repairs was pretty expensive for my friend... But I got a great price on an A4 with a brand new engine!
