Desperate for help, car makes strange noise when switched off
Hi all, I have a 1990 c230k sport. I have had the car about 2 years it has had a strange electrical fault since I have had the car, windows sporadically refuse to work, alarm goes off without reason, central locking won't work etc. Normality is returned when I disconnect the battery for a few seconds. However, today after doing this it's making a quiet high pitched beeping noise from the passengers side of the engine bay. Worried about a flat battery for the morning, I have disconnected it, noise stops.
Please, can anyone out there suggest whats wrong.
