I've had quite a lot of water in the driver's footwell over the rainy weather we've had. I noticed there was moisture in the trim just above my head over the door so I assume water may have been coming in through the sunroof. I cleaned the sunroof seal which was dirty but I can't see any problems with other seals around the door, also the sunroof seal doesn't look to be that water tight to me anyway. Since I did this it has hardly rained to see if it is still leaking (typical!). I noticed there are some drainage channels from the sunroof that go down the door pillars. I wonder if these have got clogged up with dirt and the water was overflowing? Anyone know how to clean these channels out? It's an 02 2.2 HDi SE.
