This article explains the commissioning and repair process of the Audi A6L (2013) headlight lighting range control unit (J431). It details the mounting locations for both left-hand drive (LHD) and right-hand drive (RHD) models:

• LHD models: J431 is located behind the utility box on the driver’s left side.

• RHD models: J431 is located inside the glove compartment on the driver’s right side.
  For vehicles with bending lamps, the J745 control unit and its 26-pin black connector (T26a) should also be checked.
  Before replacement, verify the drive type (LHD/RHD) and consult the official Audi service manual for detailed guidance.
  The article highlights that although the control unit’s position differs from typical components, it can be easily located based on the vehicle’s configuration.
