i brought it back to that place and they checked it out for an hour and didnt charge me for that and said my control unit/computer needs to be replaced cuz its burnt and melting. and he called bmw for the CU and it cost $400 from dealer and its a special order and have to wait 2-3days. so he told me it would cost me total of $600 for that unit and diagnostic. dunno if they over charged me or not but it needs to be fixed. im also worring if it needs to be recoded or programming my key/remote or something from bmw. that problem that i had is pretty weird, it was like some1 in the CU just shutting down each section, like my alarm, it was working fine wen i came out of my house then wen i got to the mechanic and i lock my car, the lights dont blink but it will have the chirp sound. i really like this car and dont wanna let go. now i have to walk in this rain/sleet/snow here in MA and probably not gonna be fixed until mon or tues.
