Recoding Locking Control Module

[nene]

Recoding the RS6 locking control module. Full write up at:
hypertension-motorsports

I exchanged my UNI-COM, which did not fully work on the C5 platform, for a Hex-USB VAG tool. Really good purchase in my opinion.

I enjoy the fact that once I unlock the car using the remote, I am able to unlock all four doors. I also enjoy that I am able to open or close all car windows using the remote.

If you like this kind of functionality, then recoding the locking control module is for you.

I have only tried the recoding on a 2003 Audi RS6, which comes with the Symphony radio. Please note that
Audi of America (AoA) does not officially recognize the existence of this feature as of this posting. Although many dealers know this feature exist, most are unwilling to assist you in the recoding.
This modification can be done using Ross-Tech's VAG tool. If you don't have one handy, you might be able to find another Audi enthusiast that is willing to help you using the VAG Tool Locator.

Warnings:
1: Vehicle should be turned off and in 'Park'.
2: Please read instructions fully before attempting modification.
3: I assume no liability or responsibility for any damages that may arise either directly or
indirectly as a result of the application of the information provided herein.
4: Codes tested on US bound RS6 only.

Run a test to make sure the change took place. If the test is not successful, unlock the car using the key on the door
instead of using the remote. Change the settings back to default if you wish.
