Question about BMW M Series

1 Answer

The electric roof on my convertible BMW M Roadster (2000) was having intermittent problems - It would work one day and not another. There were no sounds of strain or breakage, just no response at all from the motor, as if there was a switch behind the brake (brake must be applied to raise/lower) and it just wasnt connecting. At one point when it wasn't responsive I accessed the pump in the trunk to manually raise it, and it hasn't worked since, even though I immediately re-tightened the valve. In addition, my rear brakes are now not working. All other lights - turn, reverse, etc - are working as normal. I find it hard to believe its all lamps going bad at once, I think it has to be related. I recently replaced the battery, I doubt it has any relation, but I was going to check to see if the contacts are good at any rate. I suppose it could be a fuse, but i have lost the owners manual. I suppose that there could be a switch behind the brake that completes the circuit for the motor and brake lights, but I could not find it in a quick inspection. Any ideas? Thanks in advance...

There is a break switch located behind the pedal that works the brake lights when the pedal is depressed. You were correct in looking for it, it is located up around the pedal shaft. It will be the only switch associated with the brake pedal. Replace the switch and you should not have any problems with it electrically.

My roof will not go down has been fine until yesterday new motto last year the red light comes on as if it's working but won't go down


There is no easy solution for this. You are going to have to take the car back to BMW service or the BMW specialist you used to replace the original motor for testing and analysis..

Don't keep trying to drop the roof down as you may not get it back up again if you do lower it and you will be in worse trouble.

BMW Z4 convertible top opened and now wont close. Motor runs then stops. Latch is stuck and the emergency pull cord will not release. How do I get to the latch to free the top?


try a spray lubricant into the motor mechanism and grease any visable wire cables that run from/to motor ,not the electrical cables the bare wire winder cables,also grease/ lubricate any accessable pivot/hinge points , gently pull the cord and gently push the roof back and forth occasionally trying motor with a bit of patience this should get the roof moving , also look for anything that may be snagging the roof/mechanism as there is a pressure protection system to stop the roof being fully closed on say someones hand so preventing injury
