Hi, I have the 306 'alarm intermittently goes off for no reason' problem. When I use the steering column switch to turn off the interior alarm then it stops going off for no reason, so it must be the interior sensors. Has anyone had this problem and fixed it? I have read that you should make sure all vents are closed as the sensors are sensitive to air pressure/movement. I have also read that removing and replacing the alarm units fuse, in the fuse box, has made the same problem go away on other peoples cars. I have tried shutting the vents but that makes no difference, haven't tried removing the fuse yet. Any other ideas, before I try that? Cheers, R.
