Voltage on height sensor
Hi guys can someone answer a question about height sensors?
My 2015 Disco 4 is riding very harsh at the moment, it is normally very smooth I feel every bump in the road. (tyre pressures are all correct)
I have taken readings of the suspension height and all seems fine, no warning lights or faults on the IID however when I look at the voltages on the height sensors I have 2.4 to 2.9 on three sensors but 0 on the front right!
Could the sensor be faulty as having no reading voltage wise? and could this be the fault with the bumpy ride?
The suspension does go up and down ok and if left in high it will warn me and drop to standard above 30mph.
Thanks for you input as always.

Do you have access to a diagnostic tool for live values? Failing that what does the 4wd info display show? Is that sensor out of kilter with the others?2016 Skoda Octavia VRS Estate

I have taken the live voltage values from my IID tool.
The other 3 sensors show a value but the front right sensor is 0.0volts..
4x4 screen shows everything in line.

Ah, sorry, re-reading I see you mention IID. Have you checked the calibration mode to see the readings (rather than voltages)? I recall there being values around the 1000 mark. You could try a calibration on just that corner to see if it has the expected effect? ie the height changes in the expected direction. The change is not always immediate / obvious though. And make a note of the original value (the IID may do this for you). Or measure the voltage at the sensor itself. Both feed and output?2016 Skoda Octavia VRS Estate

I will try to take readings from the plug when I get it on a ramp.
Always a bit nervous of altering any settings especially on EAS, just incase I make a pigs ear of it. Thanks Mike............One life live it..........
