Air suspension fault am I right ? FIXED

dazer200 · Feb 2, 2022

Hi guys just a quick one, RR all Mot'd and just home now, as soon as I drive half a mile suspension inactive on display, I cleared all faults before coming home as so I could see what new ones may come on and when I got back read codes icarsoft and went into ride height sensors and all apart from the rear right are reading a plus voltage and height and rear right is reading a minus voltage and minus height would I be right that the diognosis is rear (this) right ride height sensor ?
Also codes say suspension validity fault hence why I checked heights and voltages, many thanks.

UPDATE, was car running to low needed calibration see thread https://www.landyzone.co.uk/land-rover/air-suspension-update-fixed.377784/

What car is it? L322 sensor arms have been known to flip giving negative readings.

Sounds like the arm could have come loose?

so sorry mate 2002 l322 yes, just been out in her and re-set suspension twice when stopped......this time had plus voltage and a decent height reading ? its after you have driven say 300 yards it comes back up suspension iactive

Thats a good point mate, have ordered a new sensor but worth a look, also new droneing sound from rear/front near side wheel so a bearing next !

The little bolts that hold the arm on can rust and snap or swell the plastic..

Thank you buddy that makes sence and as the last owner of 2 years lived down a green lane and there were traces of puddle plugging under the bonnet that could be it.
Will have to wait now until my mate is back as so can get up on ramps, I severed nerves in my back so can no longer crawl under cars, I try but end up non walking zombie !

Well taken out for 30 mile drive.......not sure if diesel leaks back ?
Reset suspension and monitored it and seems as long as I do not drive over 25 MPH its fine anything over and it brings up the fault, read suspension code and it says "articulation fault"
Reading ABS it says "Transfer gearbox CAN error" "Air suspension system CAN error" and 3rd "Tempory system deactivation"
Reset all codes drive over the magic 25MPH and they all come back up.
Supply voltage is 14.2V so all good there.

Any ideas ?
