Hello all, I have a 2003 disco and I will be changing both height sensors. Actually installing them looks really easy but Im not sure if they have to be calibrated or if there is anything special i need to do.

 

yes, they should be calibrated, itll work if they arent, but the height might not be level or correct, to calibrate them you need special rover calibration blocks and a testbook

 

Just out of curiosity, why are you changing both sensors?
I have been using the same set for over 9 years and lots of Colorado trails.
Ye, I also agree they are plug and play, the ECU actually sets the height not the switches.

 

Im changing them because my LR dealer came up with faults in both sensors. Thought I could save money and do it myself but it looks like it is another trip to dealer. Thanks for the info.
