Also I think the link worked you just didn't scroll down. The top of the page has a set of selector choices ignore that Ana scroll down.
The only reason to post the link was for the top section of 4 steps to Troubleshot air suspension. Sorry it won't open for some. I did check to see if it would open after I posted it.

Link doesn't work for me either - 404 Access Denied. The CDN (Cloudflare) is doing something funky...

And sorry but the link didn’t work when i clicked on it
Thats a good point about the sensor being over rotated but how will i know how to get them to their correct point if that makes sense or should i just look into getting these calibrated?

I have seen where one air spring is leaking and the other is good. The bad side will drop all the way down and the good side stays up. As the leak gets worse the good side will start dropping. Can take a day or more to show any good side drop but as the leak gets worse both sides will drop all the way down in a few hours.

If compressor isn't running normally calibration is not going to be of help. It doesn't take long for the compressor to go bad if it has been running constantly trying to inflate a bad air spring. In other words-- the problem may have started with a leaking air spring and now has damaged the compressor.

IMO the first step is to get the compressor running normally. Depending on the year it should come on when you open a door or when the key is turned on. Normal operation is to run until it reaches normal height. There are two fuses for the compressor if you haven't checked them.

Thanks for all the input and help,
My compressor no longer kicks in at all
Ot was kicking in once ignition was on but when i had the codes scanned the bloke went to calibrate the system then cancelled out of it when he noticed the air spring was flat with no air at all
Ever since the compressor has stopped working and the self level warning comes up as soon as ignition is on now.
Ive checked the fuses in the boot they seem fine is there any other fuses?
Whats your advice on getting compressor to work normally?
And its an 2002 x5 if that makes a difference
Thanks
John

Compressor won't run if there is a fault code logged. Possibly from the incomplete calibration?

You'll need to get it scanned and the codes erased before it will run again - aside from any electrical or mechanical issues.

+1

You need to read codes to understand what's going on. After replacing the air spring you would need to use a scanner to clear the codes (calibration not needed unless sensor also needed replacement)

Could i have somehow accidentally pit it into transport mode then ? Or when it was plugged in to scanner last accidentally put it into transport mode?
And i will hopefully be having it scanned at weekend to try to get to the bottom of this
Thanks john

You must certainly could have, especially if ride height calibration was stopped before completion.

Trust me that you don't want a Zamboni ride with an eight month pregnant wife in the car.... like mine did


You really should buy a Foxwell NT-510 or ista-d and laptop/cable if you want to save money on a BMW.

There are 3 fuses for the air system, The two in the luggage area are numbers 79-7.5amps and 87-30amps. There is a third behind the glove box which is 57-7.5 amps. There is also an air system control relay there.
