Arnott RH-4268 Headlight Level Sensor - Front Left

Arnott RH-4268 Headlight Level Sensor

Arnott RH-4268 is a new front left headlight level sensor for Volvo vehicles with air suspension leveling systems. It measures chassis-to-road distance and sends that input to the ECU so the suspension can adjust ride height and maintain proper vehicle leveling.

Key Features

• New aftermarket headlight level sensor from Arnott
• Black connector color with oval female connector
• 6-pin male terminals, 1 connector
• Standard grade type
• Front left position
• Direct replacement for Volvo applications that use OE-style leveling input

Detailed Description

This Arnott RH-4268 sensor is built for Volvo S60, S60 Cross Country, V60, V60 Cross Country, XC60, S80, XC70, and V70 applications that require front left ride height sensing. By reporting suspension position to the ECU, the sensor helps the system command the air compressor and air struts to raise or lower the vehicle as needed. This part cross-references Volvo OE numbers 30782818 and 31288271 for the same application.

Use RH-4268 when replacing a worn or damaged headlight level sensor on a Volvo S60 front left, Volvo XC60 front left, or other listed Volvo models. Arnott RH-4268 supports accurate leveling input for vehicles equipped with air suspension control logic.

What It Helps Address

• Incorrect ride height readings from a worn sensor
• Suspension leveling faults caused by road debris or impact damage
• Water or salt intrusion at the sensor housing or connector
• Uneven vehicle stance from inconsistent height feedback
• Air suspension control issues related to faulty chassis position input

Installation Notes and Tips

Verify front left placement before installation and confirm connector style, terminal count, and mounting points match the original sensor. Inspect the linkage, wiring, and surrounding suspension components for corrosion or damage before fitting the new unit. After installation, clear any stored fault codes and confirm the leveling system responds correctly.

Quality Assurance

Arnott supplies aftermarket ride height sensors for vehicles that rely on electronic leveling control. RH-4268 is a new part built to replace the original sensor on the listed Volvo applications.
