This page applies to 7L Touareg models with AFS. The following example is from a 2009 Touareg:

Address 55: Headlight Range        Labels: 7L6-907-357-A.lbl
  Part No SW: 7L6 907 357 C    HW: 7L6 907 357 C
  Component: AFS-Steuergeraet    0136  
  Coding: 1290371

  Subsystem 1 - Part No: 7L6 941 329 B
  Component: AFS-Lst.-Modul l    0004  
  Coding: 00000019

  Subsystem 2 - Part No: 7L6 941 329 B
  Component: AFS-Lst.-Modul r    0004  
  Coding: 00000019

If Address 55 is not installed use the pages for addresses [29] - Headlight Aim Control Left and [39] - Headlight Aim Control Right instead.

Coding

This control module supports conventional short coding. When VCDS is connected to the control module a coding chart should appear in a pop-up balloon.

When replacing the 55-Headlight Range control module the original factory coding should be used. If the original coding is not known each coding inquiry has to be configured per vehicle based on the complete Auto-Scan and vehicle repair history. Registered Customers can email directly.

Basic Setting

Headlight Adjustment

[Select]
[55 - Xenon Range]
[Basic Settings - 04]
Group 001
[Go!]
Activate the Basic Setting.
[ON/OFF/Next]

  • The meas. block field now shows "Wait" and should switch to "Adjust Headlights" then (this may take up to 10 seconds).
  • Adjust the headlights using their manual adjusting screws as referenced against a suitable aiming target.

[ON/OFF/Next]
The adjustment should now be learned.
[Done, Go Back]
Don't forget to check/clear fault codes afterwards.
[Close Controller, Go Back - 06]

Special Notes

The AFS modules (7L6-941-329-B) are communicating properly in this example:

 Subsystem 1 - Part No: 7L6 941 329 B
 Component: AFS-Lst.-Modul l    0004  
 Coding: 00000019

 Subsystem 2 - Part No: 7L6 941 329 B
 Component: AFS-Lst.-Modul r    0004  
 Coding: 00000019

The AFS modules are Not communicating properly in this example:

  Subsystem 1 - Part No: ID-L fehlt
  Component: AFS-Lst.-Modul l    ....
  Coding: 00000255 
  
 Subsystem 2 - Part No: 7L6 941 329 B
 Component: AFS-Lst.-Modul r    0004  
 Coding: 00000019

The Coding cannot be changed in the above example. The cause of the fehlt / missing message for the left light must be corrected first. This includes Fuses, Power, Ground, Wiring Problems, Wiring Connectors plugged into the wrong locations and the actual AFS module(s).

  • When fault code: 01042-Control Module; Not Coded alone is stored after AFS module / headlight control module replacement:
    • Recode the master 55-Xenon Range module to the same value and cycle the key. The new slave module should automatically be coded.
