So I was driving round he country lanes today which I do everyday as part and parcel of my job went over a hump back bridge not at a crazy speed and message came up "off road dont exceed 30 mph" or similar then the lights went out on the suspension controls and "air suspension inactive came up on dash".

Suspension appears to be at noormal ride hieght and car is driving normally not had any problems prior to this air bags have been replaced a while back so should be ok. Tried disconnectng battery no luck.

Any ideas how I can clear and reset it all functions were working fine all day access hieght motorway hieght etc.

need a scan tool to remove the fault code pal , snap on solus or similar or a member close by with IId tool
?

I had this problem on my L322 and after much stress found the source of the problem was a blocked pressure relief exhaust on the compressor. Removed it and had no fort her issues.

did your suspension still function ok then??

Absolutely perfectly. Seems to be a well known problem see thread

Can it be cleared with any of the diagnostic programes via a computer?

Worth checking all your height sensors are still connected and working.

You will need diagnostic equipment to reset the hard fault on the EAS. You should also be able to read the faults and thus understand the problem a bit better. .

Ok guys thanks for the tips found the problem rear offside sensor has become detached at the hinge point rubber grommet that holds the rod in is perished. New sensors on order the fault is in the height sensor so I can turn it off with navcoder no fault codes on eas friend checked it all with snap on.

Same happened to me on the rear a while back. At least the rear sensors are an affordable fix with a new one, unlike the fronts! .

New sensors arrived so looks like a couple of hours under the truck Sunday morning.

ive recently renewed both rear sensors on mine , remember to disconnect the battery while you change them pal

Well new sensors fitted but suspension still all over the place getting the snap on hooked up to it later if that don’t sort it think I will have to get it recalibrated. When it’s at standard height it thinks it’s at access mode so puts its self into off road height when I drive off?

Allcomms has a calibration feature to reset the heights and faults if someone has one near by and I'm guessing IID tool as well. The fronts can go on back to front with the elbow facing the wrong way but not sure about the rear but as long as they went on the way they came off you are ok.

All sorted was a pig it had lost its reference point for some reason when it was at normal ride height it thought it was at access height. Consequently when I drove off it went to off road height then threw a fault again. Reset and reflashed the ecu with factory settings now all working thank goodness took several goes to clear it.

reads like it was in transport mode to me , like mine was pal
