Why cause this PROBLEM?
The Access Start Authorization lock module is a part of vehicle's steering column. Module failure is a common problem in Audi 2004-2009 A6/C6/S6 and Q7 model vehicles. The problem is typically identified by no start and no response from key in the ignition, or proximity access (Start button). The Start / Stop Authorization Module (along with the Electronic Ignition Switch) is responsible for key/transponder recognition, unlocking/locking of steering wheel and powering up all modules in the vehicle. If there is an issue with any of the lock module components (actuator motor, sensing micro switches, relay) or the integrated Immobilizer system Microprocessor/PCB, the module will not provide power to Terminal 15 (ignition on). End result, no ignition and no engine start. The module will typically store "00288 - Steering Column Lock Actuator Defective" fault.
