Following on from the thread about the rear lights in a Sportback, I looked at the web-site referred to. On that website there was this item a bout the wipers which looks interesting.
"The wipers on the A3 have a 'cleaning position' feature - when you turn off the ignition switch, tap the wiper stalk to 'wipe once' and the wipers will jump up midway on the windshield and stop there. That way you can fold them up for cleaning. However, I discovered yet another feature as part of this: When the wipers are in the cleaning position, you can 'wipe' them back-and-forth freely on the windshield! I expected they would be immovable like every other car, but you can actually move them to wherever you want. If you push them all the way down to the normal 'rest' position, though, they lock there and they don't move when you restart the car, so no streaks on your just-cleaned windshield!
I always use the service position when I clean the car so that I can lift the wipers clear of the screen, but there is always the chance of getting a smear on the screen when you turn on the ignition and the wipers return to their normal position from the service position.
Well I've just tried it on my Sportback and it works. Interesting all the little snippets of information that can be found.
