Hi all As above, after being left standing for a while but on trickle charge, I found that at some point the battery had exploded and left a nice pool of acid underneath the car as it had melted through the grommet in the battery box in the boot..anyway, with a new battery connected, the car starts and runs but I can't get the alarm to switch off, the only way it will switch off is if I lock the car with the key and then immediately press the key fob a few times, then it just goes quiet, but as soon as I open the door or turn the ignition on, all hell breaks loose again. It's got a BMW 2t alarm fitted according to the label on top of the siren, so I've been trying to hunt down the alarm control unit to shut it up until I can get it to BMW to reset it, but I can't find the module, any ideas anyone please, I've got the glove box out and I see the ews module, but I don't think unplugging that is a good idea, and I can't find any info on this in my manual. Is there a control module I can cut the power to, or is it integrated with the ews?
