LR4 2010 Suspension height issue

[Chrisarobin]

I have been fortunate and had minimal repair issues with my 2010 LR4 which now has close to 240k miles. General maintenance and just a good deal of TLC.
I did just notice t Mack driver side suspension was about an inch higher than all other wheels. The suspension is throwing no errors and adjusting fine for access height and off road height not in all instances the back drivers side is higher.

went to the dealer and they asked for more time with it. I couldn’t leave it and wanted to know if anyone had a quick fix which didn’t require a diagnostic tool. I am concerned that if we drive it tomorrow on the highway it will cause damage or be unsafe.

I meant to say the Driver's Back side suspension is 1" higher - any suggestions on how to correct this without going to the dealer...

Have you tried the guided suspension calibration routine in the Gap tool? It guides you through calibrating the height of each corner by measuring from the center of each wheel up to the wheel arch.

If calibration doesn’t solve it, perhaps a height sensor needs replacing?

Probably the height sensor. What does the dashboard screen show you when in suspension setting (wheel position)

I had no suspension fault errors until…today!

Now it says Suspension Failt and the rear suspension won’t inflate. It started to but didn’t finish. At first it was an intermittent error but now full time.

Any suggestions? I be not have a decent shop here that will address this. One code indicates that there was an electrical interference issue with the center ice box (which I don’t have).

What are your exact codes?

Thank you for the link. This guy is great. However I do have an error on the dash indicating SuspensionFault. I’ll start with the fuse. Other suggestions?

Again, what are your exact codes? You need to pull the CEL code that will tell you what the problem is. Otherwise, we're throwing darts in the dark.

SSM72146 - see attached - by the way, thank you all in this community for your support over the years! my guess is that I should buy a new compressor and self install it with the original so I don't need to re-code.
