Audi S8 Sunroof Drains Clogged

To unclog the drains on an Audi S8 or A8 remove the fender liners and look for the drain nipple. On the passenger side it may be behind the window washer reservoir but you can remove the nuts and slide it down enough to clean the drain and open the nipple enough to ensure this doesn’t happen again. We used a short piece of tubing inserted into the nipple and then tested both front drains by pouring water into them.
