Audi A6 (4G/4H) Advanced Front System

This page applies to Audi A6/A7/A8 (4G/4H) Chassis vehicles with Advanced Front System Xenon headlights. This can be identified by evaluating the data in the Auto-Scan:

  Part No SW: 4H4 907 357 C    HW: 4H4 907 357 A
  Component: ....AFS13.... H01 0020  
  ASAM Dataset: EV_AdvanFrontSyste 005001
  ROD: EV_AdvanFrontSyste.rod

Coding

Coding is lost when the Subsystem/Slave Headlights are unplugged so it is necessary to save the complete Auto-Scan prior to repairs. If the original coding is unknown registered users can contact us directly on a case by case basis.

• Free resources include Ross-Tech's own Forum and email.
• Paid resources include Live Telephone Support

Either way, direct inquiries must include a full Auto-Scan in addition to vehicle repair details. For example, Which parts were replaced and why.

Note: Replacement LED headlights communicate as Subsystem (Slaves) under address 09-Cent. Elect. (J519) BCM1 using Component: LED Mod1L and LED Mod1R. They must be coded per the original value in the saved Auto-Scan prior to repairs.
