I have audi A6 2002. 2 years ago there was an engine problem and I did repair it at the dealer splitting 6000 cost with Audi America. 4 months later Ignition coil light came and I got that repaired for 1800. Problem with Ignition coil surfaced again this time the dealer said it is the gasket and I ended up replacing the Gasket and all cylinders for 3800.
Last week white smoke came out of the exaust and problem was traced to coolant leak and now they tell me the engine which was repaired two years ago has a crack and need replacement
Called Audi USA. They brushed me off by say thay they will give me 2000 credit towards new car.
Any one heard of a spontaneous crack in A6 engine .
I have only 65000 miles on the car.

 

Haven't really heard of it on this particular vehicle but I know the problem itself isn't too uncommon.
