I head a lot of horror stories, family member had one and was terrible. Was a new 2008 A4, long list of failures. I avoid anything German, especially Audi. Video below give you an idea of the sheer lunacy of the design of Audi. In short, there is a filter pre turbo that mean to be there for life of the car. It clogs up easily, once clogged will destroy the 10K worth of turbos. To get to this filter takes 6hrs. Subaru takes like 20min, no 6hrs for an audi for a fatal flaw that shouldn't exist.
