Does my car have a factory alarm?
I recently picked up an 08 E92. The dealer was able to pull the original order specs and I don't see the factory alarm on there but when I lock the doors, the red light under the mirror flashes. Does this mean one of the previous owners added that alarm at some point or is it flash regardless or whether an alarm is installed (as decoy?). Any way to test this?
I tried leaving my windows down and opening the doors, but once the doors were locked, pulling on the interior door handle wouldn't open the door.
