Could you gaffer tape the rod to the sensor arm just to see if the car would settle at about the right height out of interest ?

Hi guys I had the height sensor fitted today, pleased to say as soon as I cleared the fault codes with the i930 that the suspension returned to normal height all round. I checked each wheel height and they were all the same (4mm difference on rear axle) so no calibration required.

I tested the suspension in off road and lowered mode and all is well, the live data on the i930 was also very useful - compressor temperature, resevoir pressure, height sensor voltages etc were all displayed.

Happy bunny then.
