I found the easiest route is too jack up the rear and stick it on axle stands, remove the spare wheel and work from within the cavity. Take care with the pipe unions and make sure they can move freely before trying to remove them. getting them back in place without cross threading can be good for the swear box !!

I didn't spend any money all. Cleaning and rebuilding the block is not difficult, ensure you get every last bit of silica out; the middle valve can stick so take care here, it can easily pull apart if you tug it too much.

Let us know how you get on - I'd been threatening to do mine for over 18 months but just couldn't raise the enthusiasm, glad I did and should have done it sooner !

Hi Steve,

I presume you deflate the whole system first to release the pressure, then jack it?

I did see the video on youtube from that south african chap in bare feet which didn't look to hard, but as you say it's summoning the enthusiasm particularly on these colder damp days

Another thought whilst i'm motivated & considering venturing out to have a look this afternoon. Did you manage to use the existing Voss connectors or did you have to renew them when you removed the valve (like you do when you remove the air compressor?)

Good luck

Right, All back together & the feeling in my fingers has returned from trying to connect the Voss connector up again!

Re pressurised the system, soap tested the valve & it looks ok.

Taken it up the road set it to tight tolerance & re calibrated the rear again to 485mm.






let's see how it rolls.........

That was an impulsive afternoon, but at least it's done now.

Thanks for your help guys Thumbs Up

hi skegg

hope this resolves ur issues, it’s the only thing i can think off, seeing the reservoir valves sends air to both front and rear valves , also incorporating the pressure sensor

i’m more than likely totally wrong, lol

ref the voss connectors in place of them i used brass pushfits fittings, found them considerably easier to then install the pipes

fingers crossed all is now well and u can return ur straight jacket Whistle Bow down

Must say cheers to Bodsy for his video on valve stripdown. Excellent as ever.

I'm guessing the lack of any silica suggests the compressor is in moderate health.

24 hours later.

Well now it looks as though I have an air leak. Went out 12 hours later, everything looked good. Started the motor & both the front & rear rose immediately. Censored

Took it for a run & everything was ok. Left it on the drive for another 5 or 6 hours, started it again I think the rear rose but the front was ok. I have noticed now that the compressor seems to fire every time I start the vehicle after a period of rest.

I guess none of this is normal & somehow I've causes a slow leak with removing stripping & replacing the valve.

It's now sat on the drive with fuse 26 pulled to see if it reveals any clues in the morning.

I think a visit to the dealers is on the cards Big Cry

hi mate

do u think it’s now improved the uneven height issue

wonder if it may be worth just fitting a new rear valve block , know there pigs to get to

personally i used some brass push fit fittings in place of the voss connectors , then bubble tested the joints after

fingers crossed the end is in sight with this fault Thumbs Up

hope all goes well for u

So just over 12 hours later & I've measured the heights to compare with last night after pulling fuse 26.

Front OS
Was 816, Now 812 (diff 4mm)
Front NS
Was 816, Now 810 (diff 6mm)
Rear OS
Was 840, Now 838 (diff 2mm)
Rear NS
Was 834, Now 832 (diff 2mm)

These are measurements from the ground to the bottom of the arch so there maybe +/- 1 or 2 mm in my readings.

However, it appears the front dropped more than the rear overnight! I wasn't expecting that?

I'm really not sure where to go from here. I was expecting the rear to drop as it was the rear valve that was removed. The front valve or central reservoir valve haven't been touched.

Any pointers on how the whole system can drop albeit slightly in 12 hours with fuse 26 removed?

It wasn't dropping before I removed the rear valve. Could it be a leak on the inlet to the rear valve from the reservoir that is causing the whole system to depressurise slightly overnight?

Here's a thought or two......

Thought 1.

Could the overall drop be down to a cooling of the tyres & drop in overall temperature overnight & nothing to do with EAS pressure? The vehicle hadn't been far last evening before I measures only a mile or two around town at low speed. It could explain why the front dropped more than the rear as they would have more heat to dissipate in them from braking than the rear?

Thought 2.

When I exit the vehicle & lock it it automatically drops the suspension slightly I presume to try & level. if it's drop the suspension on exit it makes sense that it has to raise it back to where it should be on entry & start up? Perhaps it wasn't doing this correctly or as quickly prior to the rear valve removal & refit & now is working more in spec?

Thoughts, experiences & feedback welcome Thumbs Up
