Evening all. I have just started to get a bong when starting and the yellow ‘Suspension Fault’ message. Ran the IID and got the attached message. There was another fault message that cleared something like height sensor physically inoperative or out of alignment but that cleared. This only started after I jet washed the arches on Wednesday. Is it time for a new height sensor?

Thanks

Just checked the live values, 5 ish volts going in, 0 volts output so am I right in thinking that the sensor has failed?

Sensor or damaged broken signal wire from the sensor back to the ecu. Just had this on my L405, broken signal wire; much tracing later and found a damaged wire in the loom just below o/s/f headlight.

Sensor signal should be between 1.2v - 4.8v (though extents of wheel travel).

Thanks - I'll have a trace of the wires into the car first and see what I can find, if anything. Dec 2021- 2010 Facelift TDV8 4.4 AB in Stornoway Grey.
