tima 5 Report post Posted November 20, 2014 Hi, My E39 alarm keeps going off at random. They keyboard mechanics of Facebook have not helped much. I have determined a few things. 1: Not bonnet thing as unplugged (Could a short in the cable cause an error) 2: Battery voltage fluctuates between 12.1 and 12.4 volts when car is off. 3: Thing in the roof has not been pulled out yet. 4: Removing the fuse stops it. But i want a working alarm. Any suggestions? Cheers Quote Share this post Link to post Share on other sites
OneStep_TwoStep 21 Report post Posted November 20, 2014 I had issues with the wiring in the flexi hose thinga between the car and the boot lid. The wires had frayed and were shorting out and making things go haywire. Not sure if it'll fix your problems but could be worth a check. Quote Share this post Link to post Share on other sites
