This is whhat happens when people who do not knwo mess with the electrics and electronics of new cars. The new cars are so sensitive in any alterations, that most car electricians have no idea what they are doing. I am sorry I cannot help yoou anymore...I believe the problem is with the alarm and probably the installation. Only an authorised BMW dealer can plug the car to diagnostics and check where is the problem and what is the cause.
