have looked at this problem before, and all have turned out to be brushes in the motor assembly, what happens is brushes wear and motor just stops in various positions,and puts the f sign in display. if you can match the brushes m8, you will cure it, hope this helps

dont forget to press thanks

yes, most common is bushes, but I have not only bushes problem.

Some times when motor stops and then heat. Temperature protections protects mosfets, but some times you have replaced mosfet's, controller's, and re-flesh, flash and epprom to do job.


Any one have thinks how to remove rotor from clutch actuator case? to replace motor bushes?
