sunroof leak
 

After a hard rainfall I found water in my cabin, wet headliner all over (mostly on the passenger (right) side down the A-pillar to the floor.

Opened the sunroof and there was moisture all around.

I dropped the headliner in the front a little at the overhead console and tightened the 2 easily accessible bolts (loose but did not see a noticeable drop.)

I will spend next weekend dropping the headliner to access the other bolts but was wondering :

1. Where are the drain holes in the sunroof so I can see if they are clogged. (saw a couple of small holes in the rear of the sunroof track,) Is there a hose there that will need to be checked as well?
2. Where do they drain ( I searched and saw in front of the front wheels?
3. Any instructions for dropping the headliner all around (remove screws in sun-visors and oh-sh!t holders, a and b pillar covers and pull from clips?) any other hints
4. I will start another thread about my parking aid fault but can the moisture up there near the buttons affect the parking aid? It's near the button to switch it on and off

Fixed...
 

Well that was the ticket, tighten the two front bolts, never got around to the others seems tight after a heavy rainstorm.

I figured out where the drains are seems they are fine.
