Was driving home last night when the sterring wheel started vibrating! At first I thought it could be the tyre but the FT indicator wasn't on but I stopped and checked and all was OK.
After a bit of investigating I found out that it's something to do with the fan! For example I set it to windscreen and the fan speed obviously goes pretty much to the top on the display and it sounded like a plane! Turning it down to just under half way and the fan slows down and quietens down. Turned the engine off and tired again and it does the same and the sterring whell and dash just vibrates and shakes. Called Audi this morning and they came pretty quick but said it needed to go to the dealers. So it is now there and I am waiting for a courtesy car to be delivered. Pain in the arse really as I bet I get a Corsa or something and I am off to Twickenham tomorrow and was really looking forward to the drive down.
