So just to conclude this episode, I ordered another sensor which this time had the same part number as the original, 1 093 700 instead of the newer type 1 093 697, sadly this gave exact same symptoms. Sensor output lost when engine not running or lights off. Leaving the lights on when starting and stopping is fine, but not practical in everyday use, as the EHC system monitors the height regardless 24/7. so even if you have the lights on when you finish your journey and get out without the error message being displayed, as you walk away from the car and the EHC doesn't see an output from pin 6 from the rear rh sensor, the compressor kicks in and jack the car up to full height and logs a fault. You could change the wiring so the ehc used pins 1,4,5 of the sensor instead, but seems a bit pointless when I dont know what effect that will have on the LWR module seeing a constant output, I am sure the 5v feed to pin 5 of the (LWR)sensor was switched for a reason.

I dug out the oem sensor, pulled it apart and verified that there was absolutely no electrical connection between the 2 halves of the sensor (pins 1,4,5 & Pins 2,3,6), by contrast the Chinese sensors have internal connections between these 2 sensor circuits.

Here's a video which shows that. Reluctant to spend any more money on this and to buy a new oem sensor from BMW until I knew for sure (lets be realistic here, the price of the oem sensor is about the same as a spring conversion kit!), I managed to get the old sensor freed off and put back together. Stuck it on this morning and everything is working as it should. Made this post and videos to help others in the same boat, I am sure there has been many people who have replaced the sensor, not fixed the problem and then ended up moving the car on or converting it to springs. I know of a 04 Range Rover near me that had endless issues, and the guy gave up and sold it in the end. I am now sure this was his issue.

To sum up. You may get away using the much cheaper chinese sensors on the other corners, but go for a oem on the rear right, or be prepared to at least change the wiring.
