Hello, I’m having trouble figuring out the source of my indicated suspension fault, even after reading all the great discussion on the topic in this forum. Please let me know what you think. Here are the details:

1. Every time I start the LR3 the compressor comes on for about 30 seconds and then stops and indicates a suspension fault.
2. If I drive off while the compressor is running, I will at times not get the suspension fault indication but it turn on eventually.
3. It is at and rides well at normal height.
4. When the vehicle is left, it remains at normal height with no apparent drop over any tire (by eye)
5. At times, if I chose to heighten the suspension before the fault symbol comes on I can without issue. It can also be dropped without issue, until the warning light comes on of course.

Let me know what you think! Cheers.

 

OK so I did my homework! After checking all heights before and after overnight sit on level ground with and without the F26 fuse pulled. The Back does not move. Front drops 1/4 inch over night equally on both sides (with and without F26 pulled). So I gather it is something with the front valve block which appears to be an easy swap. My question now is that could a slow leak in the front end valve block cause the Suspension fault error code?

THanks for input. Cheers.
