I have a 2008 ML 350 AND my alarm goes off at all hrs of the night and day for no reason. Also, my key doesnt work all the time when that happens? Any ideas on what the issue is? Anthony
Dealer diag , possible vehicle security module failure or corroded contacts in system interface to module . Also remove battery terminal connections clean thoroughly and replace (do this first corrosion at battery could create an "open condition" creating a false alarm trigger) . Rotsa ruck !
