02657 - Power Output Stage for Right Headlight (J668); Not Coded

Possible Symptoms

• Malfunction Indicator Light (MIL) active

Possible Causes

• Control Module or if Subsystem, Master not coded

Possible Solutions

• Check Control Module Coding
  • Cross Reference Control Module Coding with related Control Modules (e.g. for Country or Powertrain Settings)

Special Notes

• In case an Output Stage is being replaced, the Subsystem/Slave often cannot be coded directly. Instead recode the Headlight Aim Control Module with the proper/current Coding, this will also code the Subsystems/Slaves.
• When found in Audi A8/S8 (4E): Headlight Aim Control (Adaptive Light), perform Coding.
• When found in VW Passat (3C): Headlight Aim Control, perform Coding.
