Hi I have recently bought a 2006 Allroad 2.7TDi. One problem I'm having is is if you pull the ignition key out gently all the systems stay on, the steering doesn't lock and you can't lock the car. If you pull the key out quickly or with a bit of a twist it works fine. Can anyone tell me 1) if this is a common A6 problem and 2) how can it be fixed? My local non-franchised Audi specialist put some lock lube in (no effect) and made unwelcome noises about a whole new steering column assembly. Ouch! Many thanks for your help.
