I was under the car today trying to diagnose an airmatic issue (passenger side dropping even after replacing the air spring). I think I've narrowed it down to the solenoid valve so I wrote down the part number for the valve currently installed on the car to order a replacement.
Funny thing is, the valve that is currently on the car comes up in a search as notcompatible with the car.
My car is a 2014 E350 wagon with airmatic rear suspension. The part # is A251-320-01-58 which is apparently the valve block for 2006-2012 R-Class without airmatic.
It seems the correct part # for the car is 212-320-06-58.
