Hi all,
I’m not entirely sure where this should be posted so hopefully can be moved to a more appropriate folder/ section. Having googled and seen that others have encountered this issue, I’m posting in the hope that the information I pass on is if use to someone.
Since owning the 370 I’ve had very random and inconsistent alarm issues. The alarm would go off - usually in the middle of the night which I and the neighbours love! I tried looking into all suggestions such as battery power drop, deactivating cabin motion sensor, damp in the car, boot/bonnet latches, insects within the car, shutting air vents, wireless doorbells in the vicinity etc etc but the other night when it went off (and not sure why I didn’t notice this before) found that my drivers side window was down a tiny amount. It was obvious to see that the window hadn’t moved a fraction up when the door was closed (as it should do). This hopefully is the cure to my issue as I’m presuming then that a simple gust of wind was setting it off. As it appears to be an intermittent window mechanism fault, it would explain why the alarm sounding had no regularity. I hope at the very least this gives another option as to someone else’s shared problem so they don’t get further sleepless nights!
