Hi - I'm not a mechanic and need a little help please.
I have a 1998 R reg 520i Tourer that I love (and have spent thousands on).
Problems started about 3 months ago when the CD player suddenly stopped. A week or so later the heater fan blower stopped, then a few days later the rear wiper was dead, now the radio goes on and off at will (the courtesy light too).
Now the main beam stays on even when the lights are switched off and the is key removed.
It drives fine - although the brake light and airbag light go on and off at will, and the computer (MPG etc) works now and again.
I have been told it may be an ECU (whatever that is ?).
Can somebody help please? Is there a single control unit that handles all of the electrical listed above?
Many thanks in advance.
