What is J518 Module 

Audi Start Access Authorization J518 Module / Steering Lock, which integrates the immobilizer system function and steering wheel lock mechanism.  The module is a part of vehicle’s steering column.  Module failure is a common problem in Audi 2005-2011 A6/S6 and 2007-2015 Q7 model vehicles.  Failure is typically identified by no response from key in the ignition, or proximity access (Start button).

The AUDI J518 Module (along with the Electronic Ignition Switch) is responsible for key/transponder recognition, unlocking/locking of steering wheel and activating Terminal 15 relay to power all modules in the vehicle.

If there is problem with any of the module components (actuator motor, sensing micro switches, relay, or other electrical components within the PCB, the module will not activate Terminal 15 (ignition on), resulting in no engine start.  The module will typically store the “00288 – Steering Column Lock Actuator (N360) – Defective” fault.

By dealer standard, the module itself isn’t a serviceable item and can’t be purchased separately, which means that the dealer will want to replace the entire steering column along with the Access Start Authorization Module. The dealer MSRP to replace the steering column that integrates module is roughly $1500-1700 (depending on manual or electric height adj) for parts and $500+ labor, including the need for online Immobilizer coding with Audi master servers in Germany.
