I replaced all my shocks (ADS aka switchable sport/comfort/regular) with Arnott units about a month ago. I've been getting a suspension fault "Malfunction!" notice in the vehicle (2007 P3 ML320CDI) since shortly after the install.

Airmatic seems to work fine, car levels just fine, but message keeps recurring.

Anyone have thoughts? Carly for Benz readout enclosed

I replaced my left rear adjustable shock with a Bilstein OEM and it worked fine. The ride height and leveling is accomplished through the airmatic system not the adjustable shocks. I have also replaced both rear air springs with Arnott units and they work fine as well. Don't be offended by my stupid question, but did you reconnect the control wiring properly to the right rear shock?

If you meant to say you replaced the air spring, verify that the air hose was pressed in properly and the air spring is inflated. While parked you can reach up and feel that the air spring is inflated hard.
