My A3 is the MY10 1.9TDIe Sport and every few weeks the alarm randomly decides to go off. It's not always at similar times but mostly it is during the night or shortly before I need to wakeup, conveniently! It has been back to Audi a year ago and they simply reset the ECU. Since then it has gone off less often but it still happens.
Does anybody else have similar problems or had any solutions??
