No Wazza, the front stays where it is and the back rises, as I mentioned only when left on motorway or standard never on access. After Wammers mentioned about the timer I replaced it and it still does it, it always has, so not really bothered. This is with no load removed, not even the fat personnel

As Grrrr mentioned I thought that with the timer out that it was supposed to freeze the thing. I did the rebuild of a second hand block and resurfaced all of the valve ends and NRV's and pressure tested where I could but ya never know, strange that the issue would be the same for the original and the refurbed valve block but I guess s..t happens
