Hi guys,

Got the infamous suspension fault on the way to work today and was on the high way so I could not slow down. When I finally had a chance to pull over and do a walk around, all 4 sides had lowered to the bump stops and yes it was an extremely bumpy ride. When I turned the car on it all went away magically and the car seems fine. Because I have had this fault before I didn;t think much of it until I was on the high way and then I realized it was a bit more serious than just a max speed warning and a red triangle. I had no choice but to soldier on until I was off the highway. the only thing I noticed was a burning smell coming from the rear but so far nothing has come up.

Has anyone run into this situation before???? Any issues afterwards?

Cheers and thanks

Not sure what the issue is (would be best to get the codes read) but for future reference if you knock the gearbox into neutral you can re-start the engine while still rolling. That way you can hopefully reset the system and be not have to limp dangerously up the highway

Thanks Socast, DONE!! Here's what I got:

That's quite a list..

Looks like it itself and decided that 3 of your ride height sensors weren't right..

So it could be that the control module is on the way out, a worn wire that's earthing (I did read somewhere either on here or the American forum that a chap had a similar issue and he traced it back to a worn wire running from one of the ride height sensors, well worth a search as he had images of where the wire had broken/worn) and causing the issue or it could be as simple as the battery needs changing.

Out of curiosity what was the weather like ? Had it rained the night before or during your commute ?

Very good question and there may be a connection there... It has been raining non stop for the past few days to the point where there is massive flooding all over Ontario. Ottawa hasn't been hit too hard but I'm rambling. Needless to say I see how you might be thinking that all this moisture is creating an onslaught of electrical issues.

Aside from checking under the car for worn wires and such, is there anything else that can be done before I drive this thing through the dealership and shoot myself?

My next moves are going to be fuses, then get under the car and have a good look around.

Update:

So I finished work and had a look at the car. Driver's side is higher than the passenger side. Got in and lopsided my a$$ back home and used the IIDTool to re calibrate the height. It was quick and easy and it seems to have worked but I can't see this "honeymoon" lasting. I ran the codes after the re calibration and a brief test drive and here is what came up.

Might've been as simple as a re-calibration haha

Fingers crossed

Suspension on the bump stops is what happens when the suspension thinks it's got a cross articulation error. Calibration sorts that - been there, done that. 2012 SDV6 - it's missing a couple of cylinders
2008 TDV8 - it was a labour of love and is much missed

Bah!!! You think???? Dude it's a Range Rover lol, this is just a band-aid. At the least, it will buy me time.

In the meantime I am now getting some weird smell coming form the rear left area.... Yesterday morning while it was limping on the bump stops I was on the highway jumping around at around 100KPH so I'm wondering if I may have blown a seal somewhere. If I remember correctly, the air bag provides the cushioning while the internal pneumatic shock does the rest.... Just a guess.

Is it possible the smell (smells a little like burnt brake pads) is coming from the pneumatic half of the strut? I checked the rear discs and they are fine.

The air suspension on the RRS works the same as a MacPherson Strut, theres a hydraulic damper in the centre with the air bag replacing the coil spring. So I wouldn't have thought the smell would be coming from the suspension. I'm not sure what size wheel/tyres you're running but when on the bump stops they could've been fouling on the body somewhere. The other possibility is that the geometry is all wrong when dropped that low, so you will have been scrubbing your tyres so it could be that.

You know what? I have to say these trucks are pretty poorly designed underneath. a few days ago I had a look underneath and the amount of exposed wires is incredible..... All that's required is a simple plastic cover or cowling to cover it all up and theses parts would last so much longer. It really is astounding how such a prestigious and high priced vehicle lacks this simple forethought.

I don't know what the Brits and the Europeans used for traction on the roads during the winter but here in Canada we salt the crap out of the roads and you should see how incredibly corrosive all that salt is. What's worse is that it gets into every nook and cranny making sure to kill whatever isn't protected. Very sad
