Check Control Module
94 540
am getting repeated error messages which started with oil sensor warning but now also includes brake lights and boot open.
had the brake light warning a few years ago and found it was the headlight adjusters and its been fne since i disconnected them until now.
have plenty of oil, have replaced brake light bulbs and crossed battery leads and still getting the same.
Brake bulbs changed were 5 watts.spares guy thought they should maybe be higher but can't see listing for them in the bentley.
is there a common controller or something that could cause these probs as seems strange they comming from both ends of the car.
appreciate any ideas
rgds,

Brake light will be 21W. If you use 5W (for side lights) some clown may not see it and use it as an excuse why their front bumper is sitting in your back seat
thanks guys.Gives me somewhere to start chasing
