I replace four used Arnott air suspensions (Dec 2015 made, used for only 14000KM) and an used compressor on my Jag.
Also I reprogram the ASU and reset the ride height Front 386mm Rear373mm.
But after the SDD told me reprogram is done, I found out my car is not even. (lower right side)
Of course I have replaced the O rings on four air connectors. And check the reservoir by boble water, theres no leaking.
Theres no air suspension fault and SDD shows my car is fine. No code for ASU.
But I feel the suspension too soft so that my car shakes a lot.
Is my compressor's problem? If the height sensor's problem, it should be some error codes but they are not show up.


Now I pull off the fuse No.F12&F52. I will check it tomorrow.
