When I set my alarm with my remote, the alarm automatically goe's off with lights flashing. when I dis-arm and re-arm with my remote, the alarm automatically goe's off again with the lights flash. Each time I arm the alarm system, this hapens. This is a factory alarm. I don't mine donating but lets see how it work first

Hello .. thanks for the donation .. much appreciated There are numerous reasons for the alarm to trigger by itself .. could be a bad sensor/door switch etc, etc. .. I would have the vehicle plugged into a diagnostic computer to check for alarm fault codes stored on the cars PCM (computer)

Thanks Dave
I did go to a Mercedes shop today 2/25/10 and they found that my R&R PSE Pump (pump that open and close the trunk and doors) had some type of internal leaks which cause the computer to re act as if a door or the trunk was open causing the lights to flash.
Thanks Again
