Has anyone replace the rear Ride Height Sensor on a 2014 - 2016 GL350? If so, is there one or two sensors in the rear and what is the part number for the sensor and the linkage. The dealer says my linkage is seized.

 

Like the front suspension, there are ride height sensors for each wheel in the rear on the 2012 - 2016 GL350. Before replacing the linkage, try rotating it with a plier to see if it is seized/stuck. I unfortunately replaced the linkage unnecessarily and it did not fix the problem as diagnosed by dealer. My GL350 with 60K miles continues to get the airmatic malfunction warning each time it is driven. Compressor, valve controller check out OK and there are no leaks in the air springs. Suggestions/clues on how to resolve will be appreciated.
