Headlight Level Sensor for Audi A4 S4 B8 A5 S5 Rear Left Automatic Headlight Leveling Part 8K0941309D

The Rear Left Headlight Level Sensor for Audi is a precise, OEM-replacement part designed to keep your A4/S4 B8 and A5/S5 headlights correctly aligned as the car’s weight and suspension change. This sensor, built for vehicles with automatic headlight leveling, ensures your beams stay aimed where they’re needed most—reducing glare for oncoming drivers and improving visibility for you in all driving conditions. Engineered to fit the exact specifications of the Audi A4/S4 B8 and A5/S5 range (2007–2017), it delivers reliable performance without compromising ride comfort.

Key benefits include consistent headlight alignment across different loads ( passengers, cargo, and uneven road surfaces), improved night driving safety, and seamless recalibration of the lighting system after maintenance or part replacement. This sensor is a direct, plug-and-play solution that mirrors the original component’s behavior and response, so you can trust it to work with your existing headlight leveling setup.

Compatibility and fitment are verified for Audi A4/S4 B8 (2007–2015), A4 Allroad B8 (2009–2016), and A5/S5 (2007–2017). OEM No. 8K0941309D, it’s designed as a rear-left mounting solution for vehicles equipped with automatic headlight leveling and optional air suspension, ensuring a precise match to the original part’s performance. The sensor features a D-shaped 4-pin connector, GRP housing, and comes with the necessary holder, coupling rod, and holding frame for secure installation.

Benefits & Tips

• Replace in pairs when both headlights show misalignment to restore balanced beam distribution and avoid uneven glare.
• Have your vehicle’s VIN ready to confirm fitment and avoid incorrect parts during installation.
