Suspension not lowering nsr corner

Hi All.

Odd one amongst the regular suspension woes. My 2012 s/c isn’t lowering to access height only on the nsr corner. Also, separately, occasionally the front will lower momentarily and pick back up again immediately usually in slow traffic. No warning lights coming on. Any ideas what might be going on here?

All thoughts appreciated. Cheers,

Stuart.

Hi Stuart, I had a similar issue on mine when I first bought it. The offside front corner would not lower when going from normal to access. The vehicle would then think it was stuck on an obstacle and go into extended mode.

Through analysing the live data through my IID tool and the 4x4 display, I concluded that the faulty component was the offside front strut assembly.

I replaced both front strut assemblies, the ride was much-improved and the problem was resolved.

There are also other potential causes however:
- a faulty or clogged valve block (front, rear or reservoir)
- a trapped, kinked or blocked pipe
- blocked exhaust valve on the compressor
- broken down compressor drier media
- faulty height sensor(s)

You will need to work through the problem logically in terms of analysing the problem and inspecting components in order to find out where the fault lies. Kev

Thanks Kev, interesting possibilities.

I did some tests with my wife raising and lowering the car. All 4 corners raise and lower but the nsr is higher than the other corners at all times. I can also hear a compressor running after it’s settled. Would this suggest a sensor or calibration issue? No leaks, everything dry as a bone. Cheers,

Stuart.

If it's like it at all times, I'd definitely recommend running a calibration routine in the first instance.

Have a look at the 4x4 display too and monitor that when you are raising and lowering.

Does it go into extended mode when you attempt to go into access mode? Kev

Had another monitor Kev. Not going into extended mode. All green lines on the 4x4 screen but not level. No warning lights at all.

Do I need an IID to calibrate? I can’t feel anything when driving apart from a slight pull to the left. I put this down to the tyres coming to the end of their life. Probably unrelated. Cheers,

Yes, you'll need an IID tool to run a calibration.

So what actually happens when you try and go into access mode? Kev

It lowers all 4 corners. Just looks like it’s cocking it’s leg. Cheers,
