If you park the X on level ground, take a tape measure from the bottom of the rim in the center of the wheel and record your measurements to bottom of the fender on each corner and let me know what the corners read it would give us a good benchmark.

Recently my left rear was extremely low for no apparent reason, I thought it was leaking because it was 1.25 inches lower than the front right corner! I hooked up DIS and cleared the error (EHC 64 - Distortion, plausibility), and reset the corners to be evenly height and no issues since.


The system is very sensitive to having ride heights be within specified value of each other, I think the system tolerance is say 15-20 mm, if a corner reads a higher value difference, then it trips an error.

if you don't have someone local with DIS (I have it on my laptop with the Romanian software and OBD cable) you'll have to get a calibration done at the dealer.

The code you posted in post #1, sounds strangely familiar to my code, what software was used to read the errors? It says "ride heights invalid" so I'm guessing you need a recalibration of the suspension especially after replacing the rear bags and height sensor. Should be good to go after that as long as you don't have leaks in the front.
