Hey guys, My alarm was working fine until yesterday. Now it doesn't work at all, changed batteries in the fob and tried the reprograming but nothing.When I got the car the po never used the alarm and didn't know about the reprograming. I got it working about the 2nd of day of ownership. Any thoughts or ideas would be much appreciated.
i dont know your build month, but ive picked everything else for you. RealOEM is fantastic 95% of the time, but bmwfans.info is good for clarification. its essentially the same though
i dont know much about the system as non of my 5ers have had factory alarms, but yes it sure could die without blowing the fuse. dry joints etc. in fact some control units even have a small ceramic fuse inside them
