Front Left Headlight Level Sensor with GRP Housing for VW Arteon Automatic Headlight Leveling and Air Suspension
Upgrade the VW Arteon’s headlight accuracy with this genuine front left headlight level sensor from MAX NOLOGY. Specifically designed for vehicles with automatic headlight leveling and air suspension, this sensor continuously monitors ride height using magnetic induction, feeding precise data to your vehicle’s leveling system. The GRP (Glass Fibre Reinforced Plastic) housing delivers durability without adding unnecessary weight, ensuring long-lasting performance in varying road conditions. This is a genuine part built to fit the front left position on Arteon models and compatible with related VW platforms, helping maintain proper headlight aim for safer night driving and reduced glare for oncoming drivers.
Key features include a D-shaped 4‑pin connector, OEM-standard measuring range, and robust construction that keeps your headlight leveling system stable even in demanding conditions. The sensor is paired with a holder, coupling rod, and holding frame for a straightforward fitment and reliable operation. Part number 3Q0412521A (OEM 3Q0412521A) is the reference you’ll want to cross-check for compatibility.
