Bottomed out E53 via INPA susp changes, blew CV.

[jayarc]

Hi there, normally I'm a smarter human than I was today for a period of time. I bought a 4.8is which I love and the dealer manually calibrated the air susp before I left, leaving me with "Inactive susp" message etc...


I managed to install INPA and got things connected and tried many ways of figuring out the calculated ride height, the added feature that you need to drive it a little bit before it adjust got me, bad.



Eventually I noticed resetting the ECU around the suspension and then using the buttons in the car to raise it would work. I got it raised and then attempted to calibrate the car further down off the raised numbers with INPA.


I was happy to see after the "too-high" settings I had calibrated it down a bit. I grabbed my wife so she could come and test drive our new truck with me after a bunch of fixes....


We get out to the main road and it feels good so I give it some gas, the front only of the suspension had been lowering, apparently beyond regular ranges. The front of the X5 bottomed out, causing the tire to grab, the CV still trying to apply pressure blew itself out in particularly loud fashion.


First, I know I'm an idiot who has not paid enough attention and care to another great car. Normally I'm very careful and felt like I was being. Dammit.


My questions are for you guys:


1) If you can imagine the bottoming out, and CV blow out... What would you expect should be replaced. CV only, other things that got hurt in the process?


2) If any of you have more in depth details about the air suspension and INPA please link me. I've searched thoroughly and found information that lead me down the wrong road so now, after my first INPA experience I'm a little scared to proceed.


I'm a software developer so getting the computer things situated was not too hard, I really appreciate any time you take to help out. This forum has been my savior so far in getting this X5 sorted.
