We generally mess things up a couple of times before we get it right. That's L322 ownership.
You could still have the sensors 180 out iv done that twice now working on my car. Rotate the arms. Yes the sensors can only go on one way but the arms can go either forward or backwards
@steveeasyHi All,
Im a new member whos wife has a L322 2002 TD6. She has had it a couple of years and its been great, suspension has always been inactive. Anyway, it went for its MOT in November and failed on both subframes and almost every bush on the car and yes the suspension. I decided to fixit for her as she really liked it. So I found second hand subframes, replaced all bushes on rear as well as drop links, camber bolts and arms. put it back in and everything seamed fine. Removed front subframe fitted new front subframe, new track rod arms and put it all back together. id been getting various codes for the suspension such as can bus, static air pressure when filling and had cleared these.
Anyway went to take it for a MOT and the car was very low on the left hand side. Of course Garage decided not to look at it and ive got it back to fix. New codes 32 can bus fault and 64 articulation validy fault. So reading up I thought the ride height sensors were wrongly fitted easy fix. but they are not wrong. Looked in the live data and the following stands out that I don't understand.
Front left volts 35.5. front right volts 3.8. rear left volts 2.2. .rear right volts1.9.
So I got another height sensor thinking the front left was faulty and plugged it in, still very high reading 35.volts. none of which means anything to me other than it stands out. the front left strut is covered in grease, so thinking is the shock inside faulty, but not sure if it even has grease in it. its not from the drive shaft gaiters though.
2 months in now and ive no idea why its sitting low on the left hand side. but today it then went up on both sides then I get code 32 can bus fault. I don't like passing it on to a garage but wonder if they will just chuck new parts on and still not function properly. also strange unit on rear subframe with two airlines connected with an electric plug connected. Looks in a bad way. not been able to identify it.
Any help appreciated

@steveeasyOK.
this morning before I left car sat perfectly. cleared codes and it dropped. took the day off work, drove 30 miles and when I got there told me could not reconfigure suspension today now but would read my codes instead. whats new !!. Still He thinks the problem is not the front left but the rear right. Said had to do continuity tests on wiring. Still not sure what the valve is on the rear subframe. when I removed the rear subframe it was attached to the top of it but the two pipes had rusted and fallen off. I thought it was the crossover valve but not sure.
The heights were all mad on his machine but he says due to the potential faulty sensor on rear. The volts issue actually was not shown on his reader . Car drove like a crab. think I need to get the camber bolts set properly. put new ones in so should be relatively easy.
So some progress. Think im going to look at the rear height sensors then.

May be the cross-link valve, this I believe opens/operates only in off-road mode and allows more suspension articulation.Dwarfer,
Thanks for the advice. Ill see if I can pick up some of that spray. Seams like im going to be paying a bit more attention to the system now. Its my wifes car and she was happy with it in inoperative mode. Still don't know what this valve is on top of subframe. the Guy at garage did not really know either and they do nothing but RR. When the RR failed its MOT on subframes, both LR Garages near me had never replaced a subframe. Probably why they don't know about this valve.

I've never checked the whole system, I just clear the faults and do the calibration which just involves a few simple steps.
My foxwell set the car at a calibration height then you measure all wheel heights from the bottom of the rim to the bottom of the wheel arch and enter them into the foxwell which then works out the rest.
Not sure I understand this bit but im sure its relevant ,could you make it clearer for a L322 numpty please.Oh and the tracks on the sensors wear at the normal ride height bit so if the suspension is off the car will be reading a good part of the sensor.

That's sounds great. I wonder if that is all that is needed. have you had similar issues then to alter settings.
Steveeasy
ok, understand now. your saying if it is in a different position it may not be throwing a code, but if when it returns to its normal ride height it might well do. is that correct ?. good point would not have considered that.Oh and the tracks on the sensors wear at the normal ride height bit so if the suspension is off the car will be reading a good part of the sensor.
