Hey all - I seek guidance please.....
I recently had some issues with my air suspension which involved two leaky rear bags and a leaky valve block. I replaced and rebuilt with success a couple of months ago. I also chucked a rebuilt pump at it for good measure.
All air connections have been checked with leak detector spray (fancy stuff in a spray can)

Now a new issue has surfaced.....

On standard ride height the car constantly adjusts (rises and drops) on one corner, causing the pump to run a lot. It seems to be the front left.... (Near side) Pump shuts off, front left drops, then rises, pump comes on again over and over again. If I lock it in highway mode it behaves itself. This has become a lot worse after the biblical rain we had recently.

I suspect a dodgy height sensor but it has never thrown a fault code? Has anybody else suffered similar symptoms that could help?

I should also mention I calibrated the system when I bought the car with height blocks made from hard plastic rod. I did notice the rear offside sensor showed wildly different numbers to the others but it seems to behave and sits level on that corner....

dicky height sensor, wont throw code cos technically the ecu thinks nowt wrong with it, all the ecu is doing is responding to its output.
