Hi Guys

I recently brought a E36 compact that has been parked up for 2 years the only problem im having getting it through a mot is with the alarm it wont stop going off i have recently put a new battery on it but it still did this before i put it on once i charged the old battery. I figure i need to reset the alarm. The alarm i got is the 3g mk2 but i dont no where my module receiver is any one know ? and also will resetting the alarm fix the problem in the 1st place
