Not good... I think you need to hook up a PIWIS and see if the control unit is working.

cleared error codes with PIWIS all works, annoying.

After a dead battery, the end limit positions must be relearned. Can be done with the switch, I just forget what the actual procedure was. Sorry. Check your owners manual. I'm sure its in there.

That procedure only applicable if roof responds to switches. My roof was absolutely dead. Had to be reset with PIWIS
