I've posted a couple of timeas about the problems i'm experiencing with my alarm. I've had the local dealer dump the diagnostics from the car(f.o.c i might add!) and they suspect that it's one of the ultra-sonic interior sensors that's causing the problems. They cleared the faults out and sent me off to see if the problem persists. Guess what? It does! So, if it is the sensor they suggest, they want £220 to replace. That seems a bit steep to me, but i'm not sure what else i can do. The other interesting point is that when i try and disable the interior monitors using the button on the b pillar it makes no difference and the alarm will still go off at random. Help!
