Audi R8 headlight, new, part number 4S0 941 086 F, right side.

Part Number: 4S0 941 086 F (4S0941086F) Generation: Gen 2 (4S) Facelift / Performance (2019–2023) Position: Right Hand Side (Passenger Side for LHD / Driver Side for RHD)

The 4S0 941 086 F is the companion to the left-side unit mentioned previously. This is a New genuine Audi Laserlight assembly, featuring the iconic blue “X” design and the advanced Matrix LED/Laser hybrid system. This part is a direct factory replacement for the R8 V10 Performance and 2019+ facelift models.

Technical Specifications

• Light Design: Full LED with Laser high-beam spot.

• Range: Up to 600 meters (High Beam).

• Functions:

  • Dynamic Turn Signals: Integrated sweeping LEDs along the upper edge.

  • Matrix Beam: Selective dimming to avoid dazzling others.

  • Cornering Light: Speed and steering-dependent side illumination.

• Identification: Visible blue laser module internals and “Audi Laser Light” lettering.

Key Installation Requirements

Since this is a New unit, specific procedures must be followed to ensure full functionality:

1. Transfer or New Modules: If the unit is “bare,” you will need to install the LED control units and Laser drivers.

   • Note: Using old modules on a new housing is possible, but they must be flashed with the correct parameter set for the facelift software.

2. Calibration: The Laser module is extremely precise. After installation, the headlight must be calibrated using a specialized optical headlight aimer and Audi ODIS software. If the vertical/horizontal alignment is off by even a fraction of a degree, the Laser function may be automatically disabled by the car for safety.

3. Protective Handling: Do not touch the internal components or the rear vent membranes. These “New” units are vacuum-sealed at the factory to prevent internal condensation; breaking the seal incorrectly can lead to fogging.

Comparison: Standard LED vs. Laser Light

Inventory Note: This “F” suffix part number is strictly for the right side. Ensure your vehicle has the 8IZ PR-code (Laserlight) on the build sheet, as these are not a simple plug-and-play upgrade for cars equipped with standard LED headlights without significant wiring harness modifications.
