Arnott RH-3590 Suspension Ride Height Sensor - Rear Left

Arnott Rear Left Ride Height Sensor

Arnott RH-3590 is a new suspension ride height sensor for the rear left side on select Audi, Porsche, and performance models with air suspension. It measures chassis-to-road distance and sends that signal to the ECU so the system can adjust air strut pressure as needed.

Built with durable injection-molded resin, a black female connector, and rugged mounting points, this Arnott NEW sensor is tested to 1 million cycles for long service life. It is a direct-fit replacement for rear left applications on the Audi A6, A7, A8, Q5, RS7, S6, S7, S8, SQ5, and Porsche Macan.

Detailed Description

Arnott RH-3590 is a suspension ride height sensor that monitors the distance between the vehicle chassis and the road surface, then relays that information to the ECU for air suspension control. On applications such as the 2012-2018 Audi A6 and A6 Quattro, 2012-2018 Audi A7 Quattro, 2011-2018 Audi A8 Quattro, 2009-2018 Audi Q5, 2014-2018 Audi RS7, 2013-2018 Audi S6, S7, and S8, 2014-2017 Audi SQ5, 2016-2017 Audi A7, and 2015-2025 Porsche Macan, this sensor supports proper rear left suspension feedback. The RH-3590 part number is also useful when cross-referencing OE-style replacement needs for the same application.

Arnott’s NEW product line focuses on replacement suspension components built with quality materials and application-specific fitment. For shops and owners servicing Audi A6/A7, Audi A8, or Porsche Macan rear left air suspension systems, RH-3590 provides a direct replacement option for a worn or damaged sensor.

What It Helps Solve

• Incorrect ride height readings from a failing rear left sensor
• Air suspension compressor cycling caused by bad sensor input
• Uneven vehicle stance or suspension leveling issues
• Warning lights related to suspension height control
• Damage from road debris, water intrusion, salt exposure, or impact

Installation Notes and Tips

Verify rear left fitment by year, make, and model before installation. Inspect the connector, wiring, and mounting points for corrosion or damage, since sensor faults can be caused by related harness or bracket issues. After replacement, clear any suspension fault codes and confirm the vehicle levels correctly through the full range of ride-height operation.
