Help Another electric roof problem


I have spent many hours trying to figure out whats wrong with my electric roof, with only partly success so far.
My partly success is that it was low on hydralic fluid, so topping that up at least gave me SOME movement
The symptoms are no movement at all opening the roof, but it will almost close (missing the final 15cm or so) after having opened it manually.
I have connected to the ECU with AlfaOBD and have read out the following errors:

Fault code N1:
5th bow resting right lock switch
Fault present
Fault code N2:
Hood cover left lock closed/open switch
Fault present
Fault code N3:
Warning lamp in Short circuit to + battery
Fault code N4:
Warning lamp in Open circuit or Short circuit to ground
Fault code N5:
Generic error
Fault present

That covers most things nicely, especially the last one
If anyone knows anything about faults N2, N3 or N4 I would be very interested to hear about it!
