Detailed Description

RH-3588 is an Arnott aftermarket ride height sensor built for Audi vehicles equipped with air suspension. It measures the distance between the road and the chassis, then relays that information to the ECU so the system can command the compressor to add or release air from the struts. This helps maintain proper ride height and suspension response on models such as the Audi A6, Audi A7, Audi A8 Quattro, RS7, S6, S7, and S8.

This part cross-references Audi 4H0941285G for the same application.

What It Helps Address

• Incorrect ride height readings
• Air suspension warning lights or fault codes
• Uneven vehicle stance at the front left corner
• Delayed or improper air suspension adjustment
• Sensor wear from road debris, water, salt, or impact damage

Installation Notes and Tips

Verify the connector style, terminal count, and front left mounting location before installation. Inspect the surrounding suspension linkage, wiring, and mounting points for corrosion or damage, since a failed sensor can be affected by debris or moisture intrusion. Confirm the vehicle is listed in the fitment data for your exact Audi model and year before replacement.

Quality Assurance

Arnott backs this aftermarket ride height sensor with its industry-leading warranty. The part is built from quality components and tested for extended cycle life to support long-term use in Audi air suspension systems.
