Drainpipe from the panorama sunroof DIY E70

Some people have mentioned that theirs got stuck too, yet some people mentioned that it worked for them--there might be some model years where it does work and some where it doesn't.

This happened to me too--it drained into the light fixture right over the rear passenger-side seat. I could see the water beading up right at the edge of where the light fixture is press-fit into the ceiling and used a paper towel to soak up the water. I sprayed water into the retractor tracks thinking they would drain out the rear drain pipes, but nope. Thinking about it now, that makes sense, as these two tracks are never going to get water in them while the sunroof is closed. They are covered by glass and are not under the seam between the metal roof and the glass.

Your idea of using both water and air is great, especially for those who have access to an air compressor hose and don't want to neck-down a garden hose with adapters.

Both of mine were open but I did get a little dirt out of both. These I cleaned from the rear as I could not find access from the front. They feed from under the fixed glass in the rear of the sunroof. I ran my wire up through these on each side.
Leaks are fixed.

Your rear drains are in the same place as mine (not too surprising since we have the same model year). I also was not able to locate the entrances to the rear drain pipes from their front side. I'll try running a wire into them from the rear exit like you suggest, though I am very sure they are not clogged. Might as well clean them anyway because of the horror stories about the water flooding the battery compartment if the rear drains get plugged up.

Thanks for the tips and the warning about the wind dam's brittleness. I'll keep that in mind next time I clean the drains.
