Arnott RH-5046 Headlight Level Sensor - Front Right

Arnott RH-5046 Headlight Level Sensor

Arnott RH-5046 is a new front right headlight level sensor for vehicles equipped with air suspension height monitoring. It measures chassis-to-road distance and sends that signal to the ECU so the suspension system can adjust ride height as needed. This replacement is relevant for Audi Q2, Audi Q3, Volkswagen Jetta, and other VW/Audi applications that use a front right level sensor.

Key Features

• New aftermarket headlight level sensor from Arnott
• Front right position
• Pin terminal type with 1 oval connector
• Male terminal design
• Standard grade type
• Direct replacement for vehicles using this sensor location
• Cross-reference: URO 5Q0412522C

How It Works

The RH-5046 monitors suspension position by tracking the distance between the road surface and the vehicle chassis. That input is sent to the ECU, which then signals the air suspension compressor to raise or lower the air struts. On Audi and Volkswagen models, a worn sensor can affect ride-height control and trigger suspension-related faults. Arnott RH-5046 restores the signal needed for proper leveling on the front right side.

• Delayed or improper compressor response
• Damage from road debris, water, salt, or impact exposure

Installation Notes

Verify connector shape, terminal type, and mounting location before installation. This sensor uses a single oval connector with male pin terminals and does not include mounting hardware. Confirm front right placement and match the original sensor configuration on the vehicle before replacement.

Quality Assurance

Arnott supplies aftermarket ride height sensors for air suspension systems, and RH-5046 is a new replacement part built for the specified application. It is engineered to restore the signal used by the ECU for suspension leveling on compatible Audi and Volkswagen models.
