I'm sure that's your problem. I screwed up mine once too... During the calibration it will ask you to take measurements. Make sure you pay attention and take the measurements at the right point and use the the correct units
I screwed it up and the ride height was maxed out and hard as a rock. Then I ran over the AC adapter for my laptop and shorted out the laptop. It was a week before I could get another laptop and reload the software so I could fix it.

Using TwinPoppa's guide, I enter 707mm (stock sport front with 20" wheels) + 25mm (I want to lower 1 inch all-around) = 732mm for the fronts. For the rear left, it's 709mm + 25mm = 734mm. Since the rear right is 1" higher, I entered 709mm + 50mm (2" lowered) = 759mm.
Now they are even 1" lowered all-around. Remember you have to be on level ground.
I send you a PM with my number if you need help.
are you using DIS 4.4? I dont see this option in DIS 5.7.
INPA allows me to put in values to raise my rear end but nothing happens after I press OK.
INPA/DIS4.4 & 5.7 allow me to manually activate the compressors but as soon as they finish raising the vehicle begins to drop back to height it was.
I'm convinced I screwed up some ride height values last time (2 weeks ago) I was INPA now. now to fix them (phew, at least its not a mechanical issue). but new air bags wont hurt either. the old ones looked cracked and very soft.

i cant track this down for some reason in DIS. will look further.
Will also look at Jopecasa's suggestion too but INPA was not allowing me to change ride height.
EDIT: it was allowing me to input values BUT nothing was immediately happenning after I pressed OK. It required me to restart the vehicle and THEN it adjusted the ride height. what a pain in the butt.

so using DIS 4.4 I managed to manually adjust height by activating the raise left, raise rear axel features to the same matching heights then EXTREMELY QUICKLY I pressed the Set Zero Point which then held the suspension at this new height of 710mm in rear. Fronts are not adjustable and sit about 700mm. then I needed to perform a Error Delete using INPA or DIS 4.4/5.7 (which I use as I've never done it with INPA before)

can you post a link to Twins Poppa's guide for DIS please? I'm using a tablet and tapa-talk app and this is garbage for searching compared to a real PC/laptop. Even a google search shows no link for a guide by Twins Poppa

INPA allows me to put in values to raise my rear end but nothing happens after I press OK. System says the ride height will be calibrate during next drive. Sometime you can see the SAv raised or lowered right away.
INPA/DIS4.4 & 5.7 allow me to manually activate the compressors but as soon as they finish raising the vehicle begins to drop back to height it was.
I'm convinced I screwed up some ride height values last time (2 weeks ago) I was INPA now. now to fix them (phew, at least its not a mechanical issue). but new air bags wont hurt either. the old ones looked cracked and very soft.

thanks TMV. I cleared the SLI.
So i dont know where in DIS 4.4 you get to type values in for ride height. I only see that option in INPA.
so i replaced my airbags for no real reason i guess. BUT I have to say the rear suspension seems so stiff/new again. I'll keep the cracking airbags for emergency tho as they still work, just a bit tired.

You'd be better off throwing the old airbags away. Even though they may look ok, As they wear, they become porous. When that happens, the compressor runs more than it should and burns out. I went though this with our 4.8is it was an expensive night mare.
I think I had a newer version of DIS. There is a diagnostic routine that tests the whole air suspension system. During the test, you measure the height of the vehicle to make sure all sides are equal. It was during that portion of the test where I lowered the vehicle using false values...
I still have DIS but we sold the X5 years ago so I can't tell you exactly how to do it...

i will have to connect DIS 5.7 and try to track that down. i couldnt find it anywhere.
