Sunroof drain holes
1993 Audi 100 cs
After a couple of inches of rain fell in my area, when I put my car into reverse and backed up a rush of water came pouring into the cabin from the back of the sunroof. When I drove forward another rush of water came inside through the front of the sunroof. After opening the sunroof and examining the space between the interior and exterior of the car I noticed two holes, one in the front left and front right. ARE THESE HOLES DESIGNED TO DRAIN SMALL AMOUNTS WATER?

Re: Yup. Your drains must be plugged w/ debris.
I have the same problem in my 92 100s and am also interested in how to access the drain for cleaning. I just looked over the tech article that goes through how to clean on an A4. Hope you don't mind me watching for a reply with details.

Using a long, thin wire, run the wire up from the lower end to the upper end...
The front water drain tubes run down the A pillar to the inside of the front door jam (open the front door and you should see the end of the tube). There also two rear water drain tubes (L & R) that run down the B pillars. From my ETKA, the drain tubes are 1790 mm (70 inches) in length.

Hi,
The low end of each drin (F, H) is made of a rubber. This rubber can be stopped by dried mud.
Grip several times rubber with your fingers to reduce the mud dried in dust which will fall outside.
