I am getting the suspension fault light and message. It only happens when the the LR3 has been sitting idling for a few moments and not every time it sits and idles. Does not happen when driving or using the terrain select. I am thinking a ride height sensor is going bad but it is not showing its face. It has been doing this a couple of months. Please help

 

You'll need to pull codes to see what the fault is.

 

Codes.

-Compressor too slow to fill is the most likely. Ive only replaced one sensor in all the LR3s Ive worked on and it was usually not always but a front strut and an update to the compressor design.
