Sunroof leak to headliner

[Xandah1]

My 2010 'reg started getting water soaking into the headliner after several hours of heavy rain today. I did a little searching and found the following TSB: http://www.precisionframe.com/Touareg/TSB2014044.pdf . I'm not sure if it would apply to mine since it states its for 2004-2006. Does anyone else have a similar problem or any idea if this TSB would address my issue? TIA

If I had to guess you have clogged sunroof drains and they backed up causing your leak. I doubt the frame is the issue since my 10 Treg sits out and was through some heavy rain with no issue at all.

After doing some research I began to suspect the same. I'm having a hard time locating the sunroof drain holes though. My plan is to run a thin rubber tube through it and pump some water down there to see if i can clear out whatever debris may be clogging the hole. Any insight as to where I should look?

I am not sure since I have personally never ran into this issue. If you are not already a member, go to Club Touareg and do a search there. I believe there are a couple of threads with pics and directions on how to get to them as well as get them cleaned out.

In addition to what Yeti posted. You can access the front drains from up top. Open your sunroof and with a flashlight you can just see the drain holes in the corners. To test, you can carefully pour water into the sunroof surround channel and the water should immediately drain out. You'll see it under the car.

To clear mine, I used some fairly soft 14 gauge solid conductor insulated wire and snaked it down.

The rear drains cannot be reached from an open sunroof, so you have to remove the rear wheel inner liners and run the wire from the bottom up.

i'll bet it's the front drain, so yo should be able to clear it.
