The front right airmatic strut will not inflate. I have replaced the strut and the compressor and air valve block. I have also replaced the height leveling sensor. The strut remains deflated.
Help! Michael

I would check the connection between the strut and the Airmatic control module, here is a guide to help you and the wiring diagrams for the system so you can see how it works and which wires to test. If the connections are good, I suggest replacing the control unit.

I have included the Airmatic control module replacement instructions just in case. Check out the images (below). Let us know what happens and please upload pictures or videos of the problem.

Wow, I have never seen that, it looks like someone tried to cut it. This will account for the uneven stance of the car, good find.
