Not sure mine runs that often but certainly every height change.

Might be time to re-read the EAS SID Doc. I thought the pump only needs to run if tank drops below 120 psi, but maybe the ECU runs it briefly after every adjust ?
We all know the ECU software could do with some updating from 1990’s thinking.

Put windows 10 in it see what happens.
Windows 95 worked fine

The pressure switch should provide a window between off and on of around 35 PSI. So if the compressor switches off at 150 PSI it should start up again as the pressure falls to 115 PSI or below. This may vary there maybe a slightly larger or smaller window switch to switch.

Exactly what I expect to happen, but clearly not !! I suspect the switch internals have become weak over time, hence it closes early which very little hysteresis. New switch ordered, which I will test before fitting to car.

Is that controlled by the switch or the EAS ECU?

ECU pulls relay 20 on signal from switch. Also powers diaphragm solenoid to seal exhaust port. Switch open circuit compressor on diaphragm closed, closed compressor off diaphragm open..

I think my P38 is menopausal. Previously it's been rising overnight, then last week dropping down, then Sun-Mon it stayed up overnight & all day. This morning the rear right was very low again. Can't find any leaks, so I think it's just trying to mislead me !!
Does it do it with the relay removed?
If not, it could be a dodgy height sensor giving spurious readings.

They're designed to f*ck with your mind. 6 months of ownership and you're a dribbling mental wreck.

Delay relay not operational when parked, because I have a separate ignition switched relay inline with F24 that removes all power to EAS. Did it this way so I can keep the delay relay installed so diagnostics work without me swapping relays.

There seems to be some confusion here between Hydrolics and pnewmatics or is it the wine/

Wine cannot be compressed but the wind it causes can. Is that what you mean?

I didn't mention "Hydrolics", unless you consider the menopause to be non-compressible ?

L.O.L. Changed all four shocks (Monroe), all four air bags (Arnotts II), huge difference. Probably will need to refurbish the compressor eventually.And the swivels and the drop arm and the rest of the bits on the front suspension, to get 'near' perfect steering.
