Lock set or instrument cluster, procedure for replacing

WARNING: This page does not describe the selected car, but rather 12 other vehicles, including the 2005 Audi allroad, 2004 Audi allroad, 2004 Audi A6, 2003 Audi allroad, and 2003 Audi S6. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: To ensure later identification of the anti-theft immobilizer, the following steps must always be performed when replacing the lock set or instrument cluster.

Lock set with 2 part sticker
NOTE: The stickers on the key chain of the new lock set serve for identification of manual locking.
- Remove right sticker -2- (with bar-code) from key chain of new lock set and destroy it.
- Remove remaining left sticker -1- (without bar-code) from new key chain and adhere to customer key chain instead of the previous left sticker.

Control module for anti-theft immobilizer integrated in instrument cluster.

In order to replace the lock set & instrument cluster, a coded "secret number" must first be determined in conjunction with the 14 digit identification number of the anti-theft immobilizer.

Immobilizer identification number is read upon initiation of On Board Diagnostic (OBD).

See IMMOBILIZER ON BOARD DIAGNOSTIC (OBD), INITIATING .

Effective calendar date 03.11.2002, the immobilizer secret number is encoded for increased security. The encoded number is now 7-digits and is referred to as a "PIN" ("Personal Identification Number").

All models with anti-theft immobilizer are affected, regardless of generation.

The process to obtain the 7-digit PIN remains the same as with the 4-digit "secret number" previously used - that is: request via the "Warranty Information Network" (WIN). However, WIN Administration now requires additional information from both the vehicle and Dealer in order to generate the 7-digit PIN.

The PIN is only valid on the day it is requested. Thereafter, a new PIN is required.

The 7-digit PIN can only be processed and input using either the VAS 5051 or VAS 5052 with basis CD version 3.10 and higher. VAG 1551/1552 Scan Tools are unable to process or input this number.

A correct Importer/Dealer number must reside in the VAS 5051/5052 in order to request a PIN.

The requested PIN is intended for internal use only, is worthless to other Dealers and must not be shared with the customer.

CAUTION:

All Dealership VAS 5051 and VAS 5052 testers in service MUST be programmed with the correct Importer/Dealer number, as well as correct date and time.
Adaptation functions of the anti-theft immobilizer are not possible with incorrect data!
