things like this:

+ the fact that they have severe braking problems at the current a6 models (and i am not sure at which other models) make me think that audi is more looking for cost reduction than customer satisfaction. my brother had to have his brake disks replaced twice at a mileage of only 12.000 km. go ask an audi dealership about it, if they are honest then you will step aside from audi by yourself.
bmw all the way!
