What is it and what is it for?

The acronym identifies a power module for LED headlights (LED Power Module). Specifically, it is the control unit responsible for managing Matrix LED headlights.

Its main functions are:

• Power Management: Powers the individual LEDs inside the headlight.
• Adaptive functions: Allows the light beam to "cut out" other cars in traffic (selective anti-glare) and follow curves.
• Depth adjustment: Manages the automatic leveling of the beam based on the vehicle load.
• CAN/LIN communication: Receives data from the car's sensors (cameras, steering sensor) to decide how to direct the light in real time.

Technical note: Although the physical form is identical to other control units, the "AF" suffix indicates a specific hardware/software revision. It is essential to follow the code exactly to avoid communication errors on the vehicle's bus network.

Why replace it?

• Replacement is usually necessary for three main reasons:
• Moisture infiltration: This is the most common cause. If the headlight seal fails, condensation seeps down to where the control unit is mounted, oxidizing the contacts.
• Internal electronic fault: The headlight LEDs stop working or work only partially (for example, the daytime running lights work, but the high beams do not).
• Collisions: Even a small bump can damage the connector pins or short out the module's internal circuitry.
