Detailed Description

The Arnott RH-5047 is an aftermarket ride height sensor that helps the vehicle maintain proper suspension level by reporting ride position changes to the ECU. When the sensor signal is accurate, the air suspension compressor can add or release air as needed to keep ride height within specification. This part cross-references Volkswagen/Audi OE number 5Q0412521C for the same application. It is a direct-fit solution for front left applications on models such as Audi Q2, Audi Q3, Volkswagen Jetta, Volkswagen Taos, Volkswagen Tiguan, Volkswagen Atlas, and Volkswagen Golf variants that use this sensor location.

What It Helps Address

• Incorrect ride height readings from a worn sensor
• Uneven vehicle stance caused by faulty height feedback
• Air suspension compressor cycling from bad sensor input
• Suspension warning lights related to height sensor faults
• Damage from road debris, water, salt, or impact exposure
