Glad to hear that you finally got them going, what were you doing wrong? I didnt initially see the function in the manual but when I saw the little hatches infront of each headlight, I figured that what they were but didnt see any switch to activate them so also figured it was an option. I discovered how to activate them by mistake the one day.
The spray heads of mine have popped off somewhere along the line and so the water tends to gush out but it is not a feature I have ever really needed to use anyway. Still, just shows the overall thought that has gone into the car!
Edit 30 Mar 05:
Btw, thanks QTT for the video clip links, very neat to see. I had to get a friend to activate them for me to see what was going down. Audi tried to encourage me to put new units in when in fact it was only the nozzles that had gone. Will replace them at some point but not from the dealer. I hate being ripped.
