After a failed alternator and battery were replaced my entire electrical system has freaked out. 60,000mi on the dash, and my car is a brick. After a month on the lift the most well certified mechanics in my area, including some of Audi's own, are at a complete loss. The only thing we've come up with is that the computers turn on every 30 seconds while my car is off.
