My problem is that there is water leaking thru my 2003 audi a4 headliner. It is coming in on the passenger side rear. I know that it may be the drains are clogged, however, i poored some water down the drain and it seemed to drain correctly (by the rear tire). Could they be partially clogged causeing water to get in or what else could it be. PLease help. Thanks

 

The problem is the rubber connector piece at the end of the sunroof drain. You need to pull down the headliner enough so you can get your hand in there and pull the drain off of the sunroof track. Once you pull the drain towards you pry off the white rubber end, coat the inside of the rubber piece with clear silicone and put it back onto the drain. Let it dry overnight then re-install in the next day. Fixed.
