Arnott RH-5043 Suspension Ride Height Sensor - Front Left

Arnott RH-5043 Ride Height Sensor

Arnott RH-5043 is a new suspension ride height sensor for vehicles equipped with electronic struts. It measures chassis-to-road distance and sends that signal to the ECU, which then adjusts air suspension compressor output to maintain proper ride height. This front left sensor is a direct-fit service part for select Audi A4, A4 Quattro, A5, A5 Quattro, S4, S5, and RS5 models.

Detailed Description

The Arnott RH-5043 ride height sensor monitors suspension position so the air suspension system can respond to changing load and road conditions. On Audi A4, A4 Quattro, A5, A5 Quattro, S4, S5, and RS5 applications, accurate sensor input is critical for maintaining correct vehicle stance and proper air strut operation.

What It Helps Address

• Incorrect ride height readings from a worn sensor
• Uneven suspension leveling on the front left corner
• Air suspension compressor cycling caused by bad sensor input
• Suspension warning lights related to height sensor faults
• Damage from road debris, water, salt, or impact exposure

Installation Notes and Tips

Verify the connector style, terminal count, and front left mounting location before installation. Inspect the linkage and surrounding suspension components for corrosion or physical damage, since a failed sensor can be caused by debris impact or moisture intrusion. After replacement, clear any stored fault codes and confirm the system levels correctly with the vehicle on level ground.
