My 2020 L405 has suddenly started displaying “suspension fault detected” yellow message, this is very intermittent can come on several times a day then doesn’t appear for a week - it always clears when car is restarted. There doesn’t appear to be any fault at all with the suspension. Has anyone any idea? 2020 MY Vogue

You need the codes reading, just changing bits because you saw it on a forum is a great way to bankrupt yourself...  Pete

Many thanks for your answer, diagnostics have been run, the result showing that the fault is the compressor, what I can’t understand is why it’s ok for most of the time then the massage flashes up on the dash which then doesn’t appear after restarting the car and may not appear again for over a week.
There is absolutely no sign of any fault in the suspension of the car at all. I don’t mind replacing the compressor but don’t want to find that it is a problem with the software or something else.
I am quite happy to run the car until it decides that there. Is a definite fault that requires attention.
Just wondered if anyone else had had a similar problem. 2020 MY Vogue

Do you have the specific fault code/s you can share? That will likely help pinpoint the component/s that aren’t happy.

The fact it’s intermittent is a bit of a red herring as the suspension system is complex and takes inputs from many sensors etc combined with road conditions that can obviously vary - there’s a combination of these that’s throwing the error that may not be immediately obvious.

With that said, one thing you can quickly check is the brass ‘exhaust’ filter that can seemingly become clogged and slows the release of pressure from the compressor. It’s screwed into the compressor and is easily accessed with the cover removed.

As said above though, the specific codes will avoid a wild goose chase

This is what you’re looking for -

You bought a Range Rover, you have to get used to this happening....!!!!

As JCW says there are many sensors in the system, incl heat and pressure, the two have to follow a strict regime to work properly, if they vary from the expected then a fault is shown...

Just look at it as the Range Rover has given you fair warning that something is amiss and needs attention. As said, the filter is the first thing to check but that usually gives a different fault, it's a good starting point, it's free, and something you can do yourself....

32,000 and no I don’t have a warranty. This is my 5th Range River and probably the 12th LR vehicle.
Over that period of ownership the costs of warranties would probably equal the cost of a new Range Rover!! 2020 MY Vogue

The car was examined by an independent and according to their diagnostics the fault was the compressor - “that’s about £850 plus fitting” now I’ve looked online and found aftermarket compressors for less than £400. I don’t mind paying to maintain my Range Rover but I’m not going to be treated like an idiot! That’s why I was asking for other peoples experiences as usually these issues with JLR vehicles are not isolated. 2020 MY Vogue

If you are going to keep it then can I suggest you buy a GAP IID and you can diagnose most things yourself or put the codes on here to get some help...  Pete
