check your guide rail under your seat, it probably has a coin stuck in the rail.

i have all the info you need..had to do this on my brothers care...short answer is the cables stretch inside their housings.. once seat is removed you trim the casing around the cables 1/4 and reinstall the end caps on each one to make them match their paired partner cables..stupidest thing bmw ever did having two cables to control each movement causing the chairs to twist and buckle like that..compare at $1000 to have qualified service do it for you...

SOURCE: The electrically operated seats on my BMW Z3 2.8 roadster (1997) move approx. 1cm. backwards or forwards when accelerating or braking. Does anyone know how I can fix this problem?

SOURCE: passenger seat doesnt move forward or back

that motor has eithe become jammed or has gone bad. Sometimes u can replace the moor itself or you have to get a whole new seat sub-frame that has the motor assemblies on them already. getting the seat frame is the easiest repair as switching the motors can be time consumiing and difficuly if you loose a screw or washer.

It can also be theseat motor since there is seperate motors for up/down & forward/backwards. You can test the switch to see if you are getting power to the connector on the motor by using a multimeter.

If there is power to the motor, I would remove the motor and give it a tap on the ground. Alot of the time the motor is fine, and the tap will free it up again. If it doesn't work you may be up for a new seat motor. Giving mine a tap solved the issue with mine.
