my car is an e36 m3 evo..
My central locking is done by the key as i have no rcl.
My problem is that my central locking is working sometimes and then it wont. it could work all day and then not work for a week. I cannot find any patrern to its activity and non activity.
Other day it wasnt working but yet it would put up the 2 windows with the key and today it wont put up the windows with key..
I have had it with a BMW mechanic and he has tried everything and tested everything usings the BMW wiring diagrams.. he had came to the conclusion that it was the Gm module, so luckily i knew where there was an m3 being made into a track car. Unfortunetly the track car had no battery in it so i couldnt try it before i took module out, but anyway i tried its module in my car and its the exact same, it worked for 5 or 6 opening and closings, then stoped when opening, exactly as my own module was doing.. dont know where to turn now, is it something else thats wrong? i couldnt be that unlucky that the track car module was acting exact same way? could i?
My latest discovery was this evening, i had a mate sitting in car and doors were shut, i was locking and unlockng drivers door with key, when the central locking works, the button on door car can be pushed down by hand to lock position, but when the central locking doesnt work, my mate could push down the button and it would just come back up... does this shed any more light?
