Steering Lock J518 Repair Kit 4F0905852 for Audi A6 C6 Q7 2004-2009
Audi Start / Stop Authorization Steering Lock J518 Replacement Kit
for Audi OEM Part No. 4F0905852H
The Access Start Authorization Module is part of the steering
column assembly and houses the brain of the immobilizer system as
well as moving components for locking and unlocking the steering
column. Once the steering is unlocked, it triggers ignition on the
sequence and starts the vehicle.
Background
Module failure is a common problem in Audi 2005-2011 A6/S6 and
2007-2015 Q7 model vehicles. Module problem is typically identified
by no response from the 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 the steering wheel, and power up
all modules in the vehicle. If there is a problem related to any of
the lock module moving/wear components (actuator motor, sensing
micro switches, relay) or the integrated Immobilizer system
Microprocessor/PCB, the module will not power relays to enable
ignition on or engine start. Wear and tear component-related
failure will store a Fault DTC "00288 - Steering Column Lock Actuator (N360) -
Defective".
By dealer standard, the Module itself can't be purchased separately, which means that
the dealer will want to replace the entire steering column along
with the Start / Stop Authorization Steering Lock Module.
The dealer cost to replace is roughly $1600-1800 (depending on
manual vs electric height adjustment) for parts and $1000+ labor,
including the need for Immobilizer coding with Audi online servers.
Please let us know if you have diagnosed the module with another
problem/fault (outside of the typical wear related fault resulting
in "288" - Steering Lock Defective Fault code) :
* module has previously been opened, tampered or repair attempt
carried out
* module (internal PCB) is physically or water damaged
* KEY IS STUCK IN THE IGNITION
* vehicle is newer than 2009+ (likely to have a non-wear related
module problem)
Solution
The module may need additional repairs and identity coding (and
online coding due to Microprocessor damage and identity loss). We
may need other components of the vehicle to perform coding and
inject identity back into the module from Audi online servers. or
