My Audi A6 2006 model will not start, the steering wheel is locked, no lights on the dashboard and the electric parking break won't release. The main lights are very dim , the radio works and the gear stick moves freely. I have tried spare key but still nothing happens when key is in the ignition. I have been informed by a local garage that it could be the steering column, I am enquiring to see if any one else has had this problem and what you have done about it.
