About a year ago, I had an intermittant problem with the front right height sensor. Whenever it faulted, the connector was full of water. This happened even after I waterproofed the connector, so I fitted a new sensor, no more problems.
I was curious as to how the connector kept filling with water, so I eventually got round to dismantling the sensor. Turns out the water was getting in due to a failed O ring on the shaft. Yes another O ring failure which you can see below.
You can see from the next photo that the resistive tracks are very dirty with rubber bits from the O ring
Next photo shows the resistive tracks cleaned up. You can see the grooves where the contacts move over a very small area halfway round the arc. This shows that swapping from side to side is unlikely to be a lasting solution as the wear area will be almost the same.
Just posted for anyone who wonders what is inside a height sensor, not much use otherwise.
