No worries
Bingo , with ur finding that kind of height ref that rear suspension
U say u lowered the suspension , sorry to ask but that was in normal height , not the lower access or higher off road setting please, hope that doesn’t sound rude
Great tyres are all ok , just seen so many RRS sport tyres that have been put on and there not suitable for D3s, sidewall rating has to be a min of 111T for the D3 , so ur fine there
Try this , plse put the suspension into off road height , drive back and then forward a few metres
Then lower to normal height , the small symbol that u normally get for access and off road height should go out, orange light at the switch should stop flashing when u have it in normal height
Then with the engine running check the heights , then again with the engine off please
Just wishing to check a few things
Bless u and thks and will see if we can pin this down for u and hope the above makes sense
No worries mate , will check back in over the days and see what you’ve reported back
Hi again. Hope you had a good bank holiday weekend.
Just been in the car, highered to off-road mode, drove forwards and back a few times, went to lower the car and it faults on coming down. ‘Suspension in extended mode’ error come up in the screen.
Will attempt to locate the rear suspension exhaust and remove and see if there’s an issue with it. I will report back.

Right, spent the evening under the car with little success. Got to the compressor, and was about to remove it, then suddenly thought that there must be some sort of valve between front and back. So did a little google search and located it... that’s where it all went down hill - that’s a horribly fiddly piece of work. I got no where and will attempt again tomorrow, hopefully with more success.
Hi
Sounds like that’s the resevour valve that’s next to ur compressor
The compressor goes into that reservoir valve along with the air tank
There’s a full suspension manual somewhere , will try and find it for u as it’s shes the full system and may help showing how the system works
Here u go

Hope they help u
The extended mode is a fault height sensor or suspension needs recalibration, may even be a bad wire
Easiest way to test the exhaust , with the engine running, lower ur back passenger side window , wait till the compressor stops running , then turn the engine off, u should hear a quick hiss , this is the exhaust valve opening
If i may say there’s no point messing around with the compressor , when it goes into off road height , push the height selector lever down and it will drop
Have a read and see how u get on but can see it requiring plugging into a diagnostic , to see if any fault codes come along with what the calibration is saying
Shame ur not closer as I could have plugged mine in for u and gone through it between us

I am leaning towards taking it to a garage to get the codes read. Always like to make sure I’ve tried everything I can think of (and waste hours of time) prior to it.
The valve I’m on about is passenger side, mounted just in front of the air bag. Seems to be the valve that controls the air to either side? Read a couple of things about them becoming ceased.

Quite understand where ur coming from, indeed think a diagnostics is the way to go
I bought a reader soon after I got my D3 and best thing I ever bought and saved a fortune with not having to use a garage for diagnostics
Is the valve in front of the air compressor , if so that will be the reservoir valve block , the links will also show where they all are , there’s 3 x valve blocks , drivers front, passenger middle and passenger rear
Plse let us know how u get on
Also seeing the outrageous fees that a dealer wants for diagnostics
Ah i see the one u mean now , thought u meant the one next to the air compressor , that valve block indeed just controls the back air struts , gets its message from the back height sensors in telling it when to open and close ,all controlled by the ecu , which simply stores the calibration software etc , I replaced all 3 x valve blocks in the end but has to virtually rebuild my suspension system as it had been neglected
Have a read of those links , good bit reading , lol
There is also near the back a large connector block, can sometimes get a chaffed or broken wire , won’t hurt to have a quick look
Connector block is located near the back wheel on the chassis , has about 30 x wires in it
Difficult is not the correct word to describe how difficult removing and reinstalling that valve is. You have to be a contortionist and be wearing chainmail.
However, I did manage to get it off, disassemble the valve and find what I believe is the fault. The central piston seems to be stuck. It’s free now, and I’ll take it for a test drive tomorrow afternoon!

Hi
Apologises I can’t quite see, it may just be the outer casing , if there was any leak in the actual bag u would hear it and suspension wouldn’t raise with a hole in the side of the airbag
If u would be so kind to take a better pic plse , thks
Is the back still very high
Hi
Ah bless u, easier to see, that’s the rubber protection boot, u can buy them separately , have to remove the bottom bolt to get them on, they stop all the muck getting inside
May i ask plse , if u put the height into access mode do all four corners drop right down or is the back still high plse
If ur going to keep it for a while u could get ur own diagnostics , alas are £420 but they will do virtually everything that they do at a dealers, save u a fortune , can read and clear faults , does all the suspension calibration, live data , etc etc
Plus very handy to have , works via ur iPhone or iPad via Bluetooth
Indeed plse let us know how u get on , u might also end up with a new rear valve block but won’t know until u get the calibration software plugged in
