Arnott RH-5055 Suspension Ride Height Sensor - Front Left

Arnott RH-5055 Front Left Ride Height Sensor

Arnott RH-5055 is a new suspension ride height sensor for vehicles equipped with air suspension. It measures chassis-to-road distance and sends that signal to the ECU so the system can adjust air pressure in the struts for proper ride height. This front left sensor is a direct replacement for worn or damaged units on Audi, Bentley, Lamborghini, and Porsche applications.

Detailed Description

The Arnott RH-5055 ride height sensor helps maintain correct vehicle leveling by reporting suspension position to the ECU. When the sensor signal changes, the air suspension compressor can increase or decrease air in the struts to restore the proper stance and ride height. This part number, RH-5055, is built as a new replacement for front left applications on the Audi Q7, Audi Q8, Audi RS Q8, Audi SQ7, Audi SQ8, Audi e-tron models, Bentley Bentayga, Bentley Bentayga EWB, Lamborghini Urus, and Porsche Cayenne.

Compatible with 2017-2025 Audi Q7, front left; 2019-2025 Audi Q8, front left; 2024-2025 Audi Q8 e-tron Sportback, front left; 2020-2025 Audi RS Q8, front left; 2020-2025 Audi SQ7, front left; 2020-2025 Audi SQ8, front left; 2017-2025 Bentley Bentayga, front left; 2023-2025 Bentley Bentayga EWB, front left; 2018-2025 Lamborghini Urus, front left; 2024 Audi Q8 e-tron, front left; 2024 Audi S8, front left; 2024 Audi SQ8 e-tron, front left; 2019-2024 Porsche Cayenne, front left; 2019-2023 Audi e-tron Quattro, front left; 2022-2023 Audi e-tron S, front left; 2022-2023 Audi e-tron S Sportback, front left; 2020-2023 Audi e-tron Sportback, front left.

What It Helps Address

• Suspension warning lights related to ride height sensing
• Uneven vehicle stance or incorrect leveling
• Air suspension compressor cycling caused by bad sensor input
• Incorrect chassis height readings from a worn sensor
• Damage from road debris, water intrusion, or salt exposure

Installation Notes and Tips

Verify the connector style, terminal type, and front left mounting location before installation. Inspect the linkage and surrounding suspension components for wear or impact damage, since a failed sensor can be caused by corrosion, debris, or accident-related damage. After replacement, confirm the vehicle levels correctly and the air suspension responds normally.

Quality Assurance

Arnott supplies aftermarket suspension components engineered for air-suspension service, and RH-5055 is a new replacement part built for the listed applications. Use the OE cross-reference numbers 4M0941285C and 4M0941285D to confirm application match before ordering.
