Arnott RH-5203 Headlight Level Sensor - Front Left

Arnott RH-5203 Headlight Level Sensor

Arnott RH-5203 is a new headlight level sensor for vehicles with air suspension height monitoring. It measures the distance between the chassis and the road surface and sends that input to the ECU so the system can adjust ride height as needed. This replacement is built for front left applications on select Jaguar and Land Rover models.

Key Features

• New Arnott headlight level sensor for ride height monitoring
• Square female connector with 3 male terminals
• 1 connector, blade terminal type
• Standard grade replacement with mounting hardware included
• Fits front left position on select Jaguar XF, Jaguar XE, Jaguar F-Pace, and Land Rover Range Rover Velar applications

Fitment Details

• Fits 2016-2024 Jaguar XF, front left.
• Fits 2017-2020 Jaguar F-Pace, front left, w/o CVD (Continuous Variable Damping).
• Fits 2016-2020 Jaguar XE, front left.
• Fits 2018-2020 Land Rover Range Rover Velar, front left.

How It Works

The Arnott RH-5203 helps the vehicle’s control system read suspension position accurately so the air suspension compressor can add or release air as needed. When a ride height sensor becomes worn or damaged, the system may lose accurate leveling input, which can affect suspension response and headlight leveling behavior. This part cross-references OE numbers GX733C279AA and LR090678 for the same application.

Common Problems It Can Address

• Incorrect ride height readings from a worn sensor
• Suspension leveling faults on air-suspension-equipped vehicles
• Uneven vehicle stance at the front left corner
• Sensor damage from road debris, water, or salt intrusion
• Reduced system response after accident-related suspension damage

Installation Notes

Verify the front left mounting location and connector style before installation. Inspect the linkage, wiring, and surrounding suspension components for corrosion, impact damage, or binding before replacing the sensor. On Jaguar XF, Jaguar XE, Jaguar F-Pace, and Range Rover Velar applications, confirm the vehicle does not have Continuous Variable Damping where noted.

Quality Assurance

Arnott supplies aftermarket ride height sensors built for direct replacement use on supported applications. RH-5203 is a new part and is intended to restore accurate suspension height input when the original sensor has worn out or been damaged.
