Hi guys had amber light last night saying lean when cornering to left scanned with IID and got the following any ideas?

any update? I get the same when cornering hard to the left....only the left. Goes away if you turn off/on.....but will come back again after letting vehicle sit for a few hours then cornering left again. 2014 FF Autobiography 5.0 SC

Did you ever get this problem resolved? I have the same warning "Suspension Fault-Vehicle Lean when Cornering" message on my dashboard screen. I used an Autel scanner and received these codes (see pic). Does anyone know if this is the REAR AIR SUSPENSION VALVE BLOCK that needs replacing or is it something else? Any help would be greatly appreciated. My ACE reservoir is good and I don’t see any leaks or otherwise.

LR said they needed to replace valve block etc. I decided to live with it. RR rides great and very smooth. Only on cold starts I’ll get the light “thump” on the first sweeping left turn that triggers the light. Then rides as normal. 2014 FF Autobiography 5.0 SC

Thanks, I appreciate the update. I agree, and with the holidays around the corner, I don’t feel like sinking in $500. Mine also rides great and other than the error popping up when I start it, I can’t really tell a difference. It raises and lowers fine and the only feature that’s affected is not being able to change the custom driving modes. I was also concerned about whether or not I’m potentially causing more damage by continuing to drive it, but sounds like as long as I go easy on her, I should be good.

I can still use the rotary knob and change the terrain settings…that’s odd that you can’t. 2014 FF Autobiography 5.0 SC

It says terrain settings are unavailable. You think it’s something other than the pressure relief valve? A friend of mine mentioned the ACE system but just a theory.

Hi my warning light was only coming on intermittent at first and once I cleared it with IID tool it would stay away for a while but now it’s constantly on and I can’t clear it but car drives completely fine I think this issue is definitely related to a sensor or bad earth maybe. Range Rover Vogue SE 4.4 SDV8 SVO Stying Pack

So the error reads as though it's the ace system valve block. Pressure is generated by the pump at the engine, and there are valves in the ACE valve block which will release that pressure into the hydraulic units on the anti-roll bars.

As I understand it, each of the front and rear units is a loop circuit, and the valves can send the fluid in either direction around the loop to counter leans to either side. This may likely be why you're only seeing it happen on one side of cornering.

When I did my ACE pipe replacement, the area around the valve block was filthy, and the connectors and top of the valve block were caked in mud. It might be worth getting access to the valve block and cleaning out that whole area ( take the sill tray off basically ) and making sure the connectors are all clean and working well. It could be as simple as some moisture in there. V8 or else ...
