Did Ed ever use his plates of meat on Mikes neck?
Is Mike actually brown bread?

I think the correct Cockerney Slang for Brewer is "Annoying Tw@t".
As a relative newcomer to Rangie air suspension, I can understand Wammers' comment about when and why the system operates, as I've worked on truck air suspensions in my days as a Scania mechanic.
The height sensors tell the ECU about the attitude of the car, but there is a time delay between that signal coming in and the ECU directing air or releasing air to make a change.
The compressor is purely keeping the reservoir topped up as directed by a pressure switch, I don't see anything in the operating modes that enables the ECU to directly operate the compressor on its own.
My P38 is level and steady on its wheels, while we are working on it, it has not gone down at all, which is what we would expect.

Correct, no adjustment is made whilst the vehicle is being driven. Other than the standard to motorway above 50 MPH for 30 seconds or the return to standard below 35 MPH for 30 seconds. The only time any valve should open is when the vehicle speed falls below 1 MPH then both front valves open to equalise pressure across the axle. That is why it is important to have the front bit count within 2 side to side.
I will check my traces. I am sure the pump runs way more than just at height changes. You can hear it. It seems to do it more with low battery volts.
I can think of a reason why it might open a valve. As it goes around a bend it will shift its centre of gravity and start to lean. The sensor will change and the car will try to level, either pumping air into the low side or letting air out of the high side. This will keep the car reasonably level. Certainly it seems to wallow more if you have driven using the emergency inflation kit. If ever it opens a valve it tops up the reservoir.
The penny just hasn't dropped yet with the pulling of the delay timer technique.im failing to see the logic altogether. I'll do a bit more homework in fairness and in view of the effort everyone's put in.i doubt this is goodbye for ever, somehow.

In a 644 data point trace at the same height setting I caught 10 instances of topping a bag up, almost always the front. It doesn't do it a lot but it does do it.
I'm off to find my first L322 now to share the good news with him. He MUST be in here somewhere. Thank you all so much.
