Newbie question about tailgail lock

Hi there, working on a a A Class A140 avant guard, with 3 major issues, I think I can figure all the other issues out lol.

Issue 1 - the pneumatic pipe fitting in the rear tailgate don't come off very easy, is there a tool or a trick to pulling them apart do i can replace the brake control unit? i think that is what it's called. it will work with a bit of help so i imagine it is leaking and needs replacing. (a little white plastic thumb size oval box with a tiny rubber bag or something in it in it.

sunroof - this little sucker won't even move with the manual winder, so where do I start trying to figure out trying to take a part? please.

rear wiper not working either, maybe a relay has gone somewhere, any ideas?

question why are the rear lights bulbs so complex having a double filaments and bayonets that are off centre?

kind regards J

I managed to figure it out, the hose connector just pops off when you slip a flat screwdriver in to the gaps. the lock unit then pops out with a little help from a fine flat screwdriver. the part is a replaceable for £20 from main dealer - dear enough but not as bad as i would have thought since the only one I could get from elsewhere was having to buy the whole tailgate from a car dismantler for £90 with no guarantee that the unit would work.
