Can anybody help???
Have just sponged out ~ 1 gal of water from battery compartment.
Getting the run around from Audi dealer.
Whilst in warranty they fixed it by saying they
un-blocked some drain holes.
Now out of warranty they say it needs a new seal
costings ~?165 +fitting.
I cannot find these drain holes , can anybody help???

You can see the drain holes when you open the sky roof. You may cleen the holes by introducing a wire on them. The drain holes are located at the sides, near the end of up-glass. One drain goes in front at the lower corner of the windshield and the other one goes in the hatch. I think your problem is not the drain holes, are the water exit system from the hatch... There are also drain holes there. I hope that helped you
