Range Rover Sport Suspension Failure

[slf2012]

Hi all,

I’ve got a 2015 Range Rover Sport and today got a suspension failure warning within a minute of pulling out of my drive.

Went straight back home and parked up, and notice the rear passenger side corner is lower than the other coroners.

I’m presuming this is likely a failure of the air strut.

Is this an expensive/difficult fix?

Thanks in advance!

Could be any number of things really.

- Sensors
- Leaks in the system
- Failed valve blocks
- Wiring issue.

If it’s any consolation, it could be worse…

As bakerstreet says, it could be one of many things. Do not just assume it is a failed air strut. If you have a Range Rover / Landrover, and don't mind getting stuck in with your own repairs, it is well worth investing in a diagnostic computer. I have an iCarsoft LR LR V3.0 which cost about £160, but I wish I had spent the extra on the GAP IID, which is around £500. The GAP is Bluetooth and connects to a phone / tablet, and can be used to alter settings; it also has a very user-friendly interface.

There are other less expensive code readers that can give you some idea of the problem. I would always start by reading the codes; it will usually save you a massive amount of time and prevent you from just throwing parts at it.

Are you able to raise the vehicle still? If so, does it drop after it has been stood, and how quickly? If you can get it to off-road height, do so and remove the fuses for the EAS and watch for it dropping.

If it does drop, that suggests a leak. The RRS has three valve blocks; one in the centre and one at each end. If only one corner is dropping, I would look around the affected strut and the front valve block (located behind the o/s/f wheel arch liner to the front), spraying them with soapy water. If you find a leak, you can hopefully fix it.

If there are no obvious leaks, the valve block is worth looking at. You can buy an overhaul kit for £15: https://www.jgs4x4.co.uk/discovery-3-4-range-rover...

If it is not dropping when you do the above, have a look at the height sensor for obvious damage or poor connections. Beyond that, you really need a computer or to take it to someone.

I’ll raise you… well I’ll raise one end anyway

Out of interest, is the back at road height and the front at access height?

Air Suspension. Causing land Rover owners headaches since 1989.

Air suspension is great....when its working.

Yep!

Plastic pipe connecting the compressor to the valve body split on a hot day. Very common fault.

By default most newer LR stuff drops to access height automatically when stopping and raises back up to rideheight when you continue.

Helpfully it raises the rear first and there was enough air left in the accumulator tank to raise the back end to rideheight before it crapped out

It turned in sweet on the journey back home though

To be fair, I can raise three corners! From the hissing noise I've either got a shot airbag,knackered seal or there's a seriously pissed off boa constrictor living in my front offside wheelarch...

I’m in for this too.
Have a 2017 RRS AB Dynamic, and the suspension is playing up. Wife drove 250miles with no issues and then the battery failed. I’ve swapped that out, and now going round minor roundabouts and general corners. No pattern or consistency on side or wheel, but one side was at normal heights and the other was at access height. Amber warning on the dash.

AA have said no blown strut, and we replaced the centre valve block for the Dynamic piece at the end of last year. It’s now locked in access I think with the fuse pulled.

Will be getting it to the indie who did the valve block with an instruction to fix it. Then we’ll be getting rid as my wife has lost confidence in it. Just depends how far the scope change is: could be replacement RRS, could be Disco, could jump ship to BMW. Who knows, but this one’s days are numbered.
