Roof motor fluid level?

[A1wil]

Hi guys , quick question. I want to top up my reservoir for my roof motor. It has been relocated already to the boot, looks in good nick. Is it the little allen key plug you take out to top up? . To me the reservoir looks half full, reason why I'm checking is it needs a little help to open. It closes fine. Cheers

Yes and you should see a small + symbol and i think that is the max level. could be wrong but that's where i fill mine. i have the issue but still have to give the roof a wee nudge to get it going.
