So where did your shop say it was leaking from ?? Any close up pic of the suspect area ??

Omodos,
I read in another thread just recently when a member had a blocked sunroof drain and had interior leaks. Apparently the sunroof drains are located front and rear. I think one drain pipe runs down one of the front windscreen pillars (or both?) and obviously comes out in the engine bay somewhere and you're right with the 2 drains coming out the back next to tailgate hinges. I believe if drains can't be unblocked it's a total removal of overhead roof lining and sunroof cassette to make good. Shit that's scary and would cost some coin as well. Sorry I don't know how one would clean out the rear drains apart from what you said by gently having a poke up there. Touch wood it dosen't happen to me, you and other members.

I'd be interested to hear comments on maintaining the drains as well. Is their entry points for the drains with the sunroof open where maybe compressed air could clean/clear out these drains ??
