To make them work before I have had to erase the fault memory of the roof.

correct on that one, memory's of my roof problems have come flooding back!
mine involved a faulty relay and control unit

Yup you will need to read the fault codes. My hood stopped working after the car only just started one day (almost flat battery). The low voltage tripped various fault codes relating to rollbar, hood, and windows - all OK once these had been cleared.
