Description
AFIL Lane Departure Monitoring Sensor Number 1 For Citroën And Peugeot Vehicles. A screw that secures the unit to the wheel arch may be seized – it will need to be drilled out.
High-quality AFIL lane monitoring sensor designed for Citroën and Peugeot models. This unit restores the lane departure warning functionality and supports ADAS safety features. Ideal for professional garages and DIY mechanics who need a reliable replacement part identified by common product numbers (e.g. 9663116180, 6590W1).
Function
The AFIL sensor monitors lane markings and supplies input to the lane departure warning system. Proper operation helps the vehicle detect unintentional lane drift and provide driver warnings or corrective assistance, improving active safety on the road.

- Tips: Protect connectors from contamination, avoid bending or straining wiring harnesses, and check surrounding components for damage after impact.
Why This Part Commonly Fails
- Seized Mounting Screw: Corrosion often causes the screw that secures the unit to the wheel arch to seize — a frequent workshop observation requiring drilling out the old fastener.
- Corrosion And Water Ingress: Exposure to road salt, moisture, and debris can corrode contacts and compromise the sensor electronics.
- Mechanical Damage: Impacts from road debris or minor collisions can damage the sensor housing or mounting, affecting performance.
- Electrical Issues: Connector corrosion, damaged wiring, or poor grounding may cause intermittent faults or complete failure.
Choose this AFIL sensor when you need an exact-fit replacement identified by OE numbers like 9663116180 or 6590W1. Suitable for both workshop professionals and competent DIY mechanics who can perform removal, replacement, and necessary diagnostic checks. Replacing a faulty lane monitoring sensor restores ADAS functionality and contributes to safer driving.
