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
