as above had 2 days with no faults since checking the was ecu on the weekend, anyway popped up this morning, cleared it and checked voltages to height sensors using hawkeye so i'm hoping someone can shed some light on these.

LF voltage drops as car raises and increases as car drops height
RF voltage increases as car raises and decreases as car drops
RR voltage increases as car raises and decreases as car drops
LR voltage increases as car raises and decreases as car drops

not sure whats going on with these readings i either have one faulty sensor or 3, but not 100% sure how these should work as the car raises & drops is someone could confirm, i have a gut feeling i have a rear sensor issue. i did also have a code pop up RF sensor positive shorted to earth (or along those line) but i had just inspected the cables to it. after i cleared it, it never came back. it's a 2003 l322.

with the front left reading volts in the opposite direction it could be situated inward .
Either little elbow pointing in towards the engine rather than out towards the wing..

Good luck..

The sensor arms can go over centre and then they operate in reverse.

Thanks yes they can but however yo7 position the elbows, either inward#towards The block or outwards towards the
wings, it is not possible to get the hall sensor to read a range from 40+ volts right down to the more correct
1.5 v to 2.5 volts..

And of course right up at these voltage levels, once The fault cycle comes around you immediately get
Either ‘implausible Articulation’ and air suspension inactive and often the 3 amigos.
Also canbus fault from air sus is registered on the ABS ECU. Because the air sus has been disabled and switches off abs and hill decent etc.
