P38A Yet another EAS puzzle

97 4.6 auto
Eas is a brilliant system but it does give headaches at times
Car was fine no problems when I parked
Next day I drove about 20 feet and parked again. No alarms or anything on dash and just the standard height light. It did appear to be sitting nose up when I got out.
Next day drove it and height light went to wade height but felt as if just at front and rear was close to bump stops. Pressed button and took it to standard height.
Car then went back to wade height itself but again only at the front.
Today the light is at standard height and seems at that height at front but rear right seems to be close to bump stops.
The puzzle is that it is not showing a fault. I haven't put diag on it yet but would it show anything when the system isn't faulting?

Leaky valve block. It will fault eventually, but you might be lucky that right now the pump is keeping up with the leaks.

Thank you Pwood.
The problem with that is tho that the RR and the FR side stays low. It doesn't get to the correct height at all

Definitely symptoms of leaks & failing pump. Try letting the pump completely fill the tank before closing the door and letting it rise.

And, yes the system can log faults long before showing anything on the dash. Jumping to wade height is often an early symptom of faults, especially bad connections in Left Footwell and at Driver Pack.

Ok ta much
It also doesn't self level even tho all doors are shut overnight.
The nearside is still at standard height and offside almost on bump stops

Refurb the eas block I reckon its got to be one of the easiest jobs on the range I todo just do one solenoid at a time.

Going to do that this weekend I hope ta

Dont forget the diafrani thing

I will do my best

Bought a recon valve block from a well known auction site to fit so I can take my time refurbing my own

I sort of did that I bought an unknown one to refurb and fit to mine intending to swop them out and refurb mine later and keep as a spare it took me less than an hour to refurb mine in the end, I did have a strip down of the eBay item before hand it was so simple to do I just decided to refurb my own known good unit.

Good idea I could practise on the other one
