Air suspension gets confused? Randomly goes to extended mode

Hi - has anyone had this issue before?

My air suspension seems to be able to maintain standard height, but if you try and raise or lower the suspension it seems to get confused and randomly go to extended mode - when you try and lower it, it starts to go down then gets confused again and goes back to extended.

Some times the front will lower down and not the rear, and sometimes it will be leaning to one side when left unused.

Any clues?

it thinks its hit a rock as it was lowering too slowly, so raises again

Had exactly this, developed into a 'suspension fault' message and accompanying bong

Turned out to be front right suspension sensor seized, partially fixed with some WD40, fully fixed with a new sensor

When you say recalibration is this a digital process with the ECU? Guessing dealer/specialist only?

Have you got any more info on that mate? Not sure I've heard of that before

Can be calibrated yourself with a GAP IID BT £425 + your smart phone.

The tool can do pity much everything else, apart from make Tea.
Program keys, upgrade software, read ALL fault codes, edit CCF

And if you do go for a GAP IID, Dan is selling them at a very reasonable rate considering you will avoid all the import duty etc from Canada:

Had this and it turned out to be a seized ride height sensor.

(Only on movement up or down resulting in extended mode. No leaning to one side!)
