At first after I bought it and the dealer raised it manually (still inactive on) it held ok for about three/four weeks. After that and the cold weather the front left went down. After that I installed INPA and managed to do an ECU reset and air susp activation in INPA which re-enabled the physicial up/down susp button in the car. When that happened I hit the up button and both front wheels elevated to about the same level. The back axle has always been ok, consistent and a high height.


So after my button elevated the front wheels finally I took a test drive and nothing went down, all was good.


Then I tried to go back into INPA and make the heights more perfect. I saw the suggested values for the wheel rim to the wheel well and tried to next, set offsets in the INPA calibration.


This is where I think I went wrong. I have a feeling I'm mis-interpreting the translations for the air suspension. When you're inputting the "offset values" they give you an example equation. This - this = this. It doesn't really seem to be completely clear. You need to set -100 from what I can tell to make the suspension RAISE, a little counter-intuitive.


So after setting the offset values again, I took a drive out to the main road an in that time the front bottoms out and the wheel locks, CV with pressure applied to lock wheel blows things apart. I'm a dolt, I think?


My main concern right now is if people think that my failure here would have potentially ripped apart the front diff. The CV is definitely split where the boot is so I'm hoping that the diff is generally tough enough to deal with the "no movement" jolt it got because of my ineptitude.
