Hi Folks, a few weeks ago I parked my car and on returning noticed alarm was sounding but it wouldn’t respond to my key so I manually opened the car, still no response to the key and eventually alarm went off. But, car still not responding to the key so recovery checked battery etc and ended up putting it on skates to recover it. It’s been at an Audi specialist who’ve done numerous diagnostics on it and think it could be the control unit. Has anyone else had a similar issue, if so how was it fixed? Prior to this not had any issues, I’ve owned and driven it from new Over 4 years ago.
