Hi all,

I drop my RR down to Low and turn off engine, hop out and lock the door. RR is parked on a level surface.

But next day i come out and the front is still low, but rear is on max High.

Please how does the RR wake up when it is switched off to level the RR when it should be asleep waiting for my return.

I have a photo but no idea how to add it here

When I am released from Lockdown I will be visiting another local RR who has offered to help me setup the levelling system

cheers

There's a timer relay under the front passenger seat that wakes the system up about every 6 hours to level the car. If you take that out once you have parked the car, then it won't wake up. If it has still moved overnight, it's a mechanical/pneumatic problem, if it hasn't for some reason it is thinking it is levelling the system when it actually isn't. Why do you drop it down to low when leaving it?

From Top to bottom you've got High, Standard, Motorway and Low. Normally, assuming the car is in Standard, you can only select High or Low from the rocker switch. However, if you poke the inhibit switch next to the rocker, you can then select all heights. Simplest way to stop it waking up is to pull the timer relay out. It's easiest to get to it from the rear passenger footwell. It's a tall (about twice the height of a standard relay) black one that is next to the outer seat rail. Sometimes when you try to pull it out, the base comes unclipped which actually makes it even easier as there's enough slack on the wiring to allow you to pull it out under the front of the seat.

Must be a small dog, our 10 year old miniature Dachshund still jumps in and out of my car no matter what height it's at. In fact, he prefers going out in the car to going for a walk!

I get it out from the front of the seat. Easy when you get a feel for it.

You can replace the tall black relay with a yellow type that are in the engine bay fusebox and everything will still work, except it will not wake up and self level and diagnostics won't work, but that just a case of replacing the black relay.

If I leave mine parked on any suspension height with the timer relay pulled, it will eventually end up straining against the end stops of the shocks, way higher that "oh shit I'm beached" mode.

I think the non-return valves are leaking allowing tank pressure to blow past the "up" valve into the bag valve gallery, where it then blows past the bag valves.

Bear in mind that the valves are just seated by the spring and held closed by air pressure on the back of them - if there is sufficient pressure on the other side of the valve it will lift the rubber disc off its seat and the valve will leak. This is what the NRVs on the "up" and "down" valves are supposed to prevent.

I suspect this is why you get the "dancing front" problem when you're stopped at lights - with your foot off the brake the front suspension valves both open to equalise the pressure between left and right, and if the "up" NRV is leaking then air will just flow straight into the bags.
