Hello, I think my 2005 Allroad sunroof's drain is clogged, as I have water in the back close to the brake lights + my amplifier is making thumb noises and it seems to be affecting the alarm too. Can someone please tell me where the sunroof drains are located (I only found information for the A4).

Thank you.

I've always heard of unclogging them with compressed air, at least that's what we do with RX-7's and RX-8's.

Don't use compressed air !

Use a 6' length of weed wacker string....thread it down until it comes out at the bottom fender....then wash out the tube with a cup of water.

They are located on the front corners of the sunroof when it is open, the tube is about the thickness of a Bic pen.

There are also two drains in the rear corners of the sunroof rails, which are very hard to reach unless you remove the glass panel. Not too hard, steps are in the writeup for the headliner removal here: https://www.audiworld.com/tech/int67.shtml
Do not use compressed air, you are more likely to blow the tube off the drain's nipple, which will cause more problems!
I plan on reinforcing my allroad's sunroof drain hoses when I remove the headliner for the alcantara swap in the spring.
