The alarm on my 2002 S3 last night went off at random times through-out the night for like an hour a time, I tried leaving the car unlocked and 4 mins later it started again! 8pm, 12am, 2am, 4am till 7am. Boot, doors, bonnet and windows are all closed. Radio and lights off. What the hell is going on? I'm Taking it to the Audi garage today to get them to rip the alarm out, not dealing with that again.
