O.K. I'm new to this and am quite willing to get shot down but has anyone tried to repair a height sensor?

As far as I can see, in electronic terms, these are very simple devices. For those of you who aren't into electronics, if you've ever turned a knob to change, say, the volume on a radio then you've done what a height sensor does.

So, in my simplistic thinking, if you could replace the bit in the middle then you could refurbish a height sensor.

When a replacement costs £50 - £60 each it's got to be worth a try.

Furthermore, since the Range Rover was designed electronics have moved on and there are now totally sealed versions of these with guarantees of 40,000 actions.

Does anyone out there have any faulty height sensors that they'd be willing to post to me and I'll give it a good try and report back. If so PM me and I'll supply address. Don't worry if I don't get back quickly I'm not on here daily.

I'm also wondering if it would be possible to create or modify a height sensor to prevent, or delay, the 'out of range' fault.

Not too difficult I think to machine out the back of the housing on a lathe to remove the pot. I could not be bothered, they don't fail that often.

One thing I have learned from producing devices for sailing boats is that there is no such thing as "totally sealed"

The whole design is poor from the location of the sensors to the connector being placed where it can't fail to get wet.
Sensors inside the airbags might make more sense.

If you want to play, design a new height sensor using a strain guage:D

Well it didn't take long to get shot down.
I'd thought of strain guages but with the range of travel I couldn't picture that.
But if they don't fail that often I'll leave it alone.

The other trick is when the sensors start to wear with age,swop them over to opposite sides and then they move on a different part of the carbon track which has not been used before.;)

Does this mean you still have to calibrate the sensors using rswsolutions software?
