Yes, call me a dumbass up front so we can get that out of the way.
I picked up the iCarsoft LR v3.0 because I needed to calibrate my suspension after changing the compressor on a 2008 Jaguar XJ8 (4.2 NA). When it finally timed out, it had set my wheel heights as follows: 464mm, 413mm, 483mm, 387mm.
To the best of my knowledge, there is no shop in Montgomery, Alabama running SDD. And, if you’ve ever had your suspension this jacked up, you definitely can’t drive it anywhere on hilly terrain without slipping all over the road.
Any suggestions for getting this somewhere close to normal again?

 

If the only thing you did is changed compressor, I do not believe there is a need to calibrate suspension height!
This is goes together with getting things out of the way.
@Amazon this scanner costs over $200. I spend less on cloned mongoose cable and SDD..
Have you tried to lower car with you shiny brand new scanner? It should have capability to command system to let air out. Then try to calibrate it again.
BTW when I was calibrating mine (with SDD) it would not let me enter values above 400mm. I want to say it is a physical impossibility for suspension to reach numbers you posting..
If it does not deflate automatically, you can deflate it manually by loosing cap on supply air hose to each air spring. and try to calibrate it again.
Good luck!

 

Thanks for the insight. The car was riding very low after the swap, hence the calibration.
The current height is out of range for iCarsoft (it maxes out at 435mm), so I am not sure how it got that high. I haven’t found the deflate command yet, but my next step is to disconnect the lines at the block in the trunk to get it back into a manageable range.
