After replacing the front right-hand air spring, I am still getting the "Air Suspension Fault" message on the dash.
The car is now unbalanced at the rear with different ride heights.
My iCarsoft CR Max scanner shows the following ride heights:
Front left height sensor -39 mm
Front right height sensor -39 mm
Rear left height sensor -27 mm
Rear right height sensor -65 mm
What does the measurement, in mm refer to?
What is the reference?
Should I remove the actual rear ride height sensors and check and compare their outputs?
Could the valve block be the cause of the problem?

 

Hi Paul,

You seem to be getting ride height signals from your relevant sensors, so I assume the right rear corner of the car is the high corner?
I doubt the sensors are the issue in your case, but seeing you had the car jacked up to replace the right front strut (presumably just jacking up the RHS of the car) the right rear strut will have risen as well due to the weight being lifted off it.
Normal driving should give the car the opportunity to re-level itself after a few minutes.

This thread might be of some help if you are wanting to manually manipulate the ride height to test your system and valves.

Note: The rear valve block directs air reservoir pressure to the correct strut, but the venting process is done by a separate valve up near the compressor unit and is controlled from by the suspension module but not via the same connector you are accessing at the valve block.
You might decide to undo the plug to the valve block then let the air out of the struts manually at the air lines, then see if the car will re-level itself when reconnected.

 

Hi Mark
The left rear corner of the car is high, right is low.
I will have a closer look at the valve block next week upon my return from a long weekend away.
Thanks for your input.
