Hi all, I have a c230K sport 1990, over the two years I have had the car I have had a persistent electrical fault, windows not working, central locking not working, alarm going off for no reason, unexplained flat battery,all is restored when I briefly disconnect the battery. Well today it started making a strange quiet high pitched beeping noise on the passenger side of the engine when the engine is off and the key is removed, (I think it might actually be going when the engine is running although it's difficult to tell), which only stops when I disconnect the battery. I would be extremely grateful if some one could tell me what this is.

Yours hopefully, Tim

ps got up this morning noise still there, pulled fuse 7 in the boot noise stopped. Are these two problems related?
