I have an issue with the gong for the on board coputer (OBC) in my E36 328 Sport. It sometimes work's fine but sometimes it starts to constantly go off!
It seems to be completley random! However I have learnt that to stop it bleeping I can disconnect the blue/white wire from the gong to stop it. I have checked all the connections are intact between the OBC and the gong and all seems fine. And I've re-wired and re-soldered the wire which can shut it up to no avail!
Now it's the same noise that's made when you put the key in and start the ignition, so I was hoping someone may be able to explain to me how the ignition and OBC are linked? and what causes the gong to trigger when the ignition is turned on as I believe this may be the cause.
