Hi all, thought I should bring this to your attention...while rebuilding the eas valves I had this
Temp set up...


All 4 bags bypassing eas and individually inflated.

As I stood looking at the front of the car today the front off side suddenly dropped 4 inches, there was no escape of air and there was nothing touching it.
I checked the pressure and it had not changed.
I added pressure, it slowly increased, then plop, jumped 4 to 6 inches like a Mexican gangsters sedan.
This was probably the cause of an apparent valve block fault which a second rebuild wasn't gonna fix.
A check of the airbags and hockey stick bushes all seems in order and it has new shocks.
I haven't solved this one yet but would suggest manually inflating, deflating your bags before mucking about with the valve block if its constantly changing height.

Hope this saves someone some time and I will let you know what the problem was once I hit everything with a hammer.

Cheers.

If you're manually inflating the bags you have to put a bit in at each corner at a time. You can put about 50psi in without much happening. Then you creep each corner up in 5 psi increments and she should lift. If you do it all in 1 go there seems to be a sticking point for each bag where it unfolds itself and while the weight transfers around. If you're not careful it does suddenly launch itself and you have a wonky car! It is a last resort and you shouldn't need to go above 70 psi.
 
Well that's it then....just my bags unfolding, expanding and contracting..
Didn't think it was explosives or an unnatural gravitation shift on my front drive, im just glad I don't live where you do.
But this slow bag action must play havoc with the eas and cause the compressor to run a lot as she constantly bounces around and self levels.
I think i will stick with the relay cut off switch on the dash I fitted several years ago, just to be sure.

If the front end is maladjusted. (More pressure in one side) each time the car speed drops below 1 MPH the front valves open to equalise pressure across the axle. This may cause the front to drop slightly. This can give the impression of a dance in slow moving stop start traffic.
 
ive had to replace both rear bags today.
if it gives any more **** its going on coils
and before i hear a load of bollox about it being ruined
if you go for the terra firrma set up with their shock its great no diff to air
the trouble is folk replace springs but not the shocks
wonder why it wollows lol

A lot different to air. But carry on it's your car.

I've got Terrafirma shocks with my Dunlop air-springs and it certainly doesn't wallow. Harsh is what I'd say compared to the OEM shocks.
