Need some advice my 2001 CLK W208 320 has started setting off the alarm. Tends to happen about an hour after locking the car. It fortunately stops when I open and relock the car, but am worried it may get worse. Is it the battery needing replacing as voltage dropping? or need putting on star and resetting? I even read about spiders inside the car? Can I remove a fuse if it becomes a total nuisance or activate the towing button? Welcome any help/advice? Thanks
