Can any one give me a heads up as to what the correct voltage reading should be on the height sensors on a TD6.

I have replaced both rear sensors as one arm broke when i hit a pot hole suspension works fine. In fact I was able to calibrate it the other day without any issues however occassionall the suspension turns its self off It can run for days sometimes weeks and then all of a sudden suspension inactive.
Put the inpa on it and all seems to work fine recording correct suspension height etc the only odd thing is the voltage reading from the sensors which is :-

fr 2.87
fl 2.88
rl 1.86
rr 1.04

checked wiring no damage plug seems fine not corroded pins look good. I am wondering if the sensors faulty they were after market ones.
Any thoughts would be greatly appreciated

There's a procedure for testing them in the workshop manual which may help. See this thread : http://www.fullfatrr.com/forum/post482719.html#482719 2016 Skoda Octavia VRS Estate

Reading that I think its probably the sensor then. I have just calibrated the suspension and both fronts are showing around 2.8v which leeads me to believe that both rears should be showing a simaarl voltage to each other ie if one is at 1.86 the other should probably be the similar for the same height setting.
1.04 volts seems way low.
They were after market sensors so I will try replacing it.

Update I finally got round to swapping the offside rear sensor out yesterday and that seems to have done the trick. Recalibrated the suspension to 490mm front 480 on the rear and both rear sensors now showing 2.11 volts so must have been a duff sensor. Lesson learnt don’t buy the cheap ones!
