I have had a slew of problems with my electrical systems with my 2001 Audi A6. I previously posted about having many problems with my alternator, which has worked great for the past 6 months (knock on wood). Like many, my display screen is not visible. Recently, the screen and Bose system appear to be performing a lot worse. After leaving a light on , my battery died and a friend had to jump me. The screens resolution was restored and the Bose system sounded crystal. Over the next week both got a lot worse again.

Does this sound like a known problem? Any of you Audi wizes have an idea what might need to be fixed?
