After reset the roof ecu, and drive the car some distance, permanent fault comes back, and roof won,t open or close, when open.
With pp 2000 get this failure ( no info motor rev,s ) speedsensor is working as i can see the moving speed in pp 2000 program.

The following diagram is showed:

I would check the green wire for continuity, and the relay for correct operation.

Problem solved, the "motor running" relay was not installed, after putting a new one in, the roof opens and close as normal.

The only question is why this circuit is important, it has nothing to do with a moving or standing car, thats where the speedsensor circuit is for..

See picture:

Maybe the clue is in "no info motor rev,s". It's not KPH or MPH, so it's not speed of the car, it's probably the speed of the roof hydraulic pump motor.

[vanders]

The speed of the hydraulic pump is not measured, its the info from the engine running relay..

Does the roof work if the engine is stopped?
