If manual re-inflation of the air suspension system is required, it is important to disable the factory electronic ECU system first. The quickest way to achieve this on a P38 Range Rover 1994-2002 is to remove the delay timer which is situated under the front passenger seat, it looks like a black relay and should be the only one under the seat, please check the Part No: ANR4387 or ANR4652 before removing it. Please note: Classic Range Rovers 1992-1995 have a disable switch under the rear of the drivers seat.

No valves in bags. You would need to remove the four corner pipes from the valve block, set suspension to access and fit a Schrader valve on each one. Expect a bit of blow out, cover your eyes. Then empty the tank by pulling the feed pipe from valve block, again lots of air flying about. Unless you have diag and can evacuate the system that way. I fitted the Schrader style air valves to my Range Rover P38 in place of the air pump and valves as my EAS suspension. Why mess with it by fitting various forms of manual inflation.

Once disabled you can remove the valve caps and re-inflate the vehicles air spring using any compressed air source, such as a garage forecourt tire inflator.

When the EAS Electronic Air Suspension is disabled there is no control over the height.

A height of 450mm measured from the centre of the road wheel to the bottom of the wheel arch equates to a standard setting. Check for leaks regularly as the onboard compressor will not top up the system.

As a rough guide 50psi to 55psi (just under 4 bar pressure) is the correct pressure for standard height.

DO NOT OVER INFLATE THE AIR SPRING BAGS - you will be surprised how quickly the vehicle will rise up especially using a garage compressor. Over inflation will damage your air spring bags. They will pop just like a balloon if over inflated.
