Hi,
we had a L322 Rangerover in for MOT. Air suspension light came on after jacking up.

Found o/s/f suspension bag split, replaced strut assembly but light still comes back.

Using Maxidas code 64 articulation validity fault.
(levelling sensor fault )
on live data I'm getting voltage readings and height measurements on all sensors except OSR.
Pressure in system 11.5 bar.

Tested voltages at sensor and ok.The odd thing is when its connected to the axle, I"m getting 2.08 volts but no height reading, but if I disconnect the arm and raise the arm I start to get a height reading at 1.3 volts or lower.

Tried new LR sensor and still the same.

I"m suspecting module fault? or am I missing something.

Any thoughts appreciated.

Thanks Joe

Tried recalibration first.

Re checked live data, all voltages about 2 volts except n/s/f 26.5 volts !
Checked voltage at the n/s/f sensor and reads 2 volts, if I disconnect the sensor and manually operate the sensor I get a smooth voltage rise and fall 0 -3 .5 volts.
It seems that the ecu is interpretating the 2 volts as 26 volts.

I did have another range rover in last week ( which has an suspension compressor fault ) and checked live data on sensors, and this one also read 27v on one of the front sensors, and 2v on the others.

I would expect 2v on all sensors, is this correct?

This has only happened since Mot, cant see how the split bag has caused other issues


Any further suggestions would be appreciated

Thanks Joe
