Arnott Industries RH-3718 ride height sensor for the 2012-2018 BMW 320i and other vehicles measures the distance between the road and the chassis. The ECU uses that reading to signal the air suspension compressor to add or release air in the air struts.
- Precision sensing for accurate suspension calibration
- Helps restore ride height sensing for suspension adjustment and vehicle stability
- Lab tested up to 1 million cycles
- Increases ride comfort and dynamic capability
Quick facts

A suspension ride height sensor can wear out, and road debris, accidents, water and salt can damage it. A car that sits at the wrong height or shows an air suspension warning can mean the sensor is worn, though a failing air suspension compressor or a leaking air strut can also be the source, so find the cause before replacing the sensor.
Fits
The 2012-2018 BMW 320i, the 2018-2025 BMW 118i and the 2017-2021 BMW 230i xDrive all take two of these sensors, and many other BMW, MINI and Rolls-Royce models fit too; this listing is one sensor. If your car isn't named here, look it up in the Vehicles it fits section.
