As per title really.

My electric roof stopped working so I bought the correct fluid and topped it off, this solved the problem albeit temporarily but I've now had to top it up again so I'm guessing there's a leak somewhere (should be fun to find). I just wondered if anyone could tell me how to bleed the system once I have refilled it? I can't find this information anywhere - doesn't it need bleeding? Also, is there a correct way to reset where the roof is after you've released the pressure from the system using the handle in the boot.

Thanks in advance for any help.
