Hi, I have a p38 and sometimes after I park it , I come back and it has risen by itself to high setting. When you get in and start it ,it goes back down to standard height. Then sometimes but more rarely it is lower than standard height when I come back to it. These can happen in a space of 30mins. Also sometimes when parking just after turning the car leans to the outside of the turn if you know what I mean and does not level even if you raise and lower the suspension. It just gets higher or lower with the lean still in it. It has had a new compressor and four new bags recently.
P38 rises on its own

I took a pic of the faults logged but as I only bought the p38 a few months ago ,I don't know how old they are. I have cleared them (hopefully) and will check them again. But with all these valves stuck I take it I need to rebuild the valve block? Hopefully there is a pic attached to this post
Ok the pic didn't work! Anybody know how to upload a photo from an ipad on to this post?
In the meantime here's what it says
F8-79 F9-228 FA-0 FB-255 FCC-13
O:FL signal incorrect
1: F8:2_hidden
2:FR signal incorrect
3:F8:8_hidden
6:RR signal incorrect
2: pressure signal constantly high
5:air supply leak
6:target heights incorrect
7:vehicle has moved
0:FL valve stuck open
1:FR valve stuck open
2:RL valve stuck open
3:RR valve stuck open
4:Inlet valve stuck open
5:Exhaust valve stuck open
6:FB:64_hidden
7:FB:128_hidden
0:FL valve stuck closed
2:RL valve stuck closed
3:RR valve stuck closed
That's it !!

Valves don't stick open or closed and most certainly not at the same time. Think you have some serious height sensor problems.

That list of faults generally means you don't have good communication or possibly low battery voltage, it is impossible to have a valve stuck open and closed at the same time.
As for you problem with the heights, I agree with Wammers, probably a duff height sensor.
