    Started the car this morning and the Check Engine (DSC) light was on plus Brake and ABS lights, also speedo and energy control didn't work, so I'm picking it's time for some new Rotors and Brake Pads unless anyone knows of another problem this may be indicating.

    Are their any recommendations on replacement Rotors and Pads and do we have any discount deal with a supplier ?

    In advance thanks.

    Interesting

    All fixed - it was a problem with the rear window stop light socket which needed to be replaced. The interesting part is (as I was advised by the experts) if there is a severe problem with stop lights which will result in them not working, the cars electronics defaults the status to on-always as a safety precaution. :mellow:

    Thanks Jochen, this is the complete story so far, in case something in the process may have caused this:-

    - Initially the "check brake light" started showing but the brake lights were working.

    - then all of the brake lights stopped working, "check brake light" message still showing

    - changed 2 lower bulbs and fuse 41 no change

    - fitted new switch, no change, lights still not working

    - went to an auto electrician, he played around with switch with an amp/volt meter and the lights started working with key on, didn't work with key off, depressing brake pedal made no difference with key on or off

    - unfortunately he had no BMW manuals, so advised me to go to BMW and suggest to them the brake relay may be stuck, they weren't interested in having a quick look and suggested I book it in for a service

    - swapped old switch back in, same results as with the new switch, so something has changed

    - went for a drive, tried cruise control, turns on but won't set and hold speed, probably because it thinks the brake is being pressed

    PS - wife ran the battery flat about a month ago, not sure if this is relevant.

    Well I got a new brake light switch, installed it and now my brake lights are on all the time when the key is on (whether my foot is on the brake pedal or not), the brake lights are not on when the key is off.

    Can someone advise where the brake light relay is on an Auto 1999 E39 540 ?

    brakelight switch will be around your brakepedal somewhere. not sure on exact location. u should be able to figure out where when you look.

    heres what u need to do.

    1. get a multimeter.

    2. conect meter between light pos and earth. if it reads 12.5ish volts the fault is between the lights and ground.

    if no voltage do the following.

    3. conect the multi meter before the switch and earth is somewhere. u should get around 12.5ish volts.

    4. test for voltage after the switch when you push the brake pedal. u should get same voltage.

    5. if you can find the brake light relay test for voltage at pin 86 or 85. one of them should have voltage when you push the brake pedal. and if you flick the multimeter into resistance. the little horse shoe symbol. and conect the other terminal. (without voltage) to the multimeter and the other wire on the meter to earh you should get a low reading. prefrably under 1 ohm

    6. test for voltage in at pin 30 on the relay. and check the resistance of pin 87 and earth. that should indicate what part of the circuit the fault is it. if theres no voltage at 30 when conected to meter and ground then the fault is between there and batery

    if there high restistance on pin 87 or the meter says something like ol. then the fault is between there and the lights.

    if no voltage at 86/85 then the problembs between there and the switch.

    if high resistance on the other pin. then fault between there and earth.

    hope this helps. if you need help. call me 0212158039 i am in wellington

    Thanks I will try this out and let you know how I get on

    Regards Pete

    You could try this

    Removal of the front is really easy, I found the best way was to lift the middle of the old sill cover up about 1.5 inches and then slide the whole sill cover towards the back of the car. This will remove the sill cover and leave the old clips in place.

    To remove the old clips I used two flat blade screwdrivers and some cloth to protect the bodywork, I used the two screwdrivers under each side of the clip and pryed it out, pushing against the cloth placed on the bodywork, they come out easily.

    The rears were a bit more difficult, I found it hard to slide them out, you need to lift the 'B pillar side' as well as part of the middle of the sill cover, in the end I used the two screwdrivers to pyre out the sill cover and the clips. I damaged the clip housing on the old sill cover , but the clips themselves were ok, they are tough little things.

    I found it here in post #10
