Happy New Year everyone.

You were a massive help after my P38 conked out on the M1 last year.

The car has had four new air bags and a new compressor under 2k miles ago.

Last week the car went into limp home mode after the full light display on the dash.

I got home ok. Suspension still up when I parked and still up several days later.

I have now plugged in the EASUnlick software and it is producing the following codes.

Please can someone kindly help make sense of this for me?

Is this a valve block issue? Or ride height sensor fault?

Last time I did give the connector on the FR sensor a quick squirt of contact cleaner.

So please, would this code suggest a sensor fault or valve issue?

I'm planning on taking this to the garage to fix, so I'd much rather change just one thing that's b#ggered rather than swap out both and chuck away a perfectly working part.

The car is MY2000 with 105k miles on the clock.

Your expertise, as always, gratefully received.

I believe that Vehicle has moved can be ignored, the fr valve stuck closed is in the valve block not sure about the first one, but if the front right valve is stuck, the signal will be incorrect

The fault means the height has not changed according to sensor. If the height has not changed within a set period the valve is deemed to be shut. As said check the height sensor first.
 
Thanks all.

I'll try a bit of first aid on the height sensor to see if I can crawl the motor 2 miles to my 4x4 garage and get him to fit a new sensor.

While I appreciate it should be a DIY job, swapping out the air bags took the guy four hours last time as everything was seized solid underneath, and I'm sure something will go snap if I try to crawl under the car myself on the side of the road!

Cheers chaps
 
Update.

Bl##dy stupid car is now behaving itself. All started up no drama or fault codes. Took a while to get pressure up and lift to normal height, but we got there. ECU seems to be doing its job as I could feel it working out the levels for each corner as it settled comfortably.

Will pop back with axel stands so I can crawl under and give the RF sensor contacts another spruce up.

RF sensor has nothing to do with EAS.

If the sensor is changed, the EAS will need to be re-calibrated.

Thanks DT.

Yes, that's understood.

I was trying a spot of self-help before posting this thread and found a chap who wrote on here in 2014 about the mare he was having with his EAS going into fault mode, when it apparently self rectified a week or two later (either battery was less cold or wet electrical contact had dried out).

Hope this will be a straightforward swap out. Fingers crossed.
 
If it took a while to get pressure up you may have a leak somewhere, and if you have it will be wearing out the pump piston seal pdq.
