Unfortunately I've already done the job and didn't take any pictures. However if you are mechanically confident enough to remove the airbag then it is a simple task. You can buy the new stalk for an A1 from ebay, once the steering wheel is removed just remove the upper and lower cowling and swap the stalk cluster over. Put it all back together and get Audi to code your car.
Whole job cost me £109 as I got a new stalk cluster for £58 off ebay and my local Audi dealer charged me 30 mins labour this afternoon to code the car, they even washed and vacuumed. I didn't bother buying a new lower cowl, I just carefully cut the old one.
Took a couple of hours but most of that was because I hadn't done it before so had to work everything out from scratch.
