May be anti theft issue???
Audi A4 2010 Sedan 14000 miles
While driving, my car lost all power, no dash lights, etc. It spuddered to a parking lot. I replaced the battery, and checked all fuses, I regained power, but car still will not turn over.

CommentAudi A4 not starting
Audi A4 2005 2l tdi 1705000 miles
Got in my audi a4 earlier (2005 model) turned the ignition on... nothing working on the dash apart from the handbrake light and airbag light. Crank it, starts briefly then died. Won't start, dash lights and gauges not functioning at all! now i know that if it starts then dies straight away it's usually an immobiliser issue, but why would the dash not work? long shot, but anyone had this before? i know there are a few people on here with a4's,
