Disappointed in the D5 / waiting for the Defender

So I crossed palm then crossed back (winching of course)
And then we all drove around to the next bypass into the OTL

No stock wagon would have driven or winched down that entry without removing a few kilos of plastic rear bumper....
As it was the Pajero modified its bumper and the 200 it's rear flaps on the track from the Bramwell servo to palm .....

Anyways

If someone parked their D5 in that first drop I then could have driven over it and down to the creek without needing to winch 😀 Picture doesn't really show it too well but that first drop in is over a metre into soft intractable mud....

PS an hour with a mattock and shovel could have made a ramp down into the first slop . Which would have preserved rear bumpers on wagons but then would still need to winch through that to get down to the creek
A week later this was driveable

Yep,that's about how I remembered the tele track,have fun doing that in a stock 4wd running factory HT tyres. Pat

There are also smarts that take into account wheel spin and steering angle i believe, but i dont think there's a pressure sensor.

My assumption is the D5 uses similar logic, though i don'tknow if additional sensors are used.

The bag is part of the sensor [emoji6]

My coils have been.

I would be guessing they are quite sagged by 300kk! Measure them

Height sensor signals not changing as air is exhausted from 1 or more corners yet the sensor signals are not at their lower limit(s) indicates that the vehicle is not lowering when it should be able to go lower.

Wow...is there really a debate about reliability between coils and air...really (now some like air for other reasons...all good...but one thing they (and by that I mean bag and all the kit to keep it in the air) are not is as reliable as heat treated spring steel.

Wow what a discussion.

I have to add that on many if not the majority of Range Rover Club of NSW trip , one or more air suspended cars has a problem.

The RR club has actually bought a Testbook to take on trips.

The most recent one I know about was Geehi over last Christmas, where a RRS dropped on the left. The testbook was able to show it was the front left and eventually the owner found a screw that located the air line into the air bag had departed.
On a previous trip to SA a RR L322 lost all suspension and had to drive to Adelaide to a dealer .

Now does every owner have to buy a testbook? What happens if you are out in the desert and the suspension goes down?

IID will sort it.
Springs sag quickly, heat treated steel collapse or breaks.
An airbag can come loose or a sensor read bad.
All comes down to maintenance.

Air is better for the occupants, the vehicle, the tracks.

Then my apologies for the misinformation. [emoji29]

Have a look at the number of air suspension threads about faults on this site.

It is pretty obvious they are no where near as reliable as coils or leaves.

When working correctly air suspension is fantastic,but when it isn't working correctly it is often expensive and often frustrating to repair,trying to locate leaks,etc.

Coils or leaves are also much cheaper.

A corner valve failed on my D4,at approx 4 yrs old,50K.No amount of maintenance would have prevented the component from failing.Due to it leaking very slowly,it was very difficult to locate the exact fault.
