Finally today got around to fitting the valve block o ring repair kit to my '96 RR

Two of the non return valves (NRVs) are quite badly damaged, does anyone know where I could get a set (of 3) I don't mind if they are secondhand as long as they are in good condition.

re-built the block anyway, but still having a few issues, stopped the RR and got out to open the garage door, when I got back in it had gone to wading height on it's own.

My plan is to replace the NRVs before doing any more faultfinding.

Anyone able to help?

Thanks

Hi Mark, thanks, i'll take a look in the meantime. The o-rings I fitted are the black ones (kit from Landyair) i'll leave the NRVs for now.

I did notice while I was waiting for the pressure to build in the tank the rear was rising even though the drivers door was open. Does this point to a leaky solenoid?

I'll get back to it next weekend, reading the howto again before I start.

Cheers

Valve block arrived, salvaged the NRVs from it, swapped my new o-rings onto them and fitted in my valve block. All ok, or so I thought - drove down road no problems. Got into the RR the following day but immediately the "SLOW 35MPH" message appeared.

Turns out when the laptop is plugged in the message doesnt appear, and everything suspension related seems to behave. (apart from the odd time the selector switch doesnt respond)

With laptop unplugged the "slow 35mph" message comes up on the message centre. If the laptop is disconnected when in the motorway position, the suspension doesnt rise back to normal when the vehicle slows down (after 6 miles of driving at approx 30mph)

From what i've read on here the next step is to check exhaust filter, height sensor connectors, the sensors themselves and connectors in the eas box under the bonnet.

I've got a spare driver pack but am not sure of its condition - came from eBay with the valve block. May try swapping it out also.

Anything else i've missed?

Cheers
