My 97 Range Rover was starting to nose up overnight and dance a little while driving so I decided to replace the o-rings and diaphragm with parts from Rover Renovations. After putting it all back together I'm having a couple of issues.

- First, I'm getting a "RR Signal Incorrect" fault. Not sure if this is just a problem with the sensor being out of range as it doesn't appear if I jack up the right rear an inch or two.

- The main problem is the vehicle not rising at all. I took everything apart again and noticed a couple of o-rings on the steams were pinched. Put it all back together and still no movement after 15+ minutes. Don't notice any leaks except for maybe one really small one on the compressor connector. When I disconnect the air lines there seems to be no pressure in the system.

Anyone have any ideas on what I should check next?

Thanks,
Marty Allen

that could be your only problem, if it's leaking at a low pressure, you'll never build up a higher pressure. the compressor is low-volume, high-pressure so a small leak there could knock the whole system out.

also, one of the most common errors (with those symptoms) is getting the non-return valves back incorrectly, one goes the opposite direction of the other 2, if you get them in wrong it won't work right at all.

As Dennis said. Ive just done my block, and after leaving it to build up for 15 mins there was still no pressure in the system. I eventually found a small leak in the line that comes from the dryer. Tiny, but enough to prevent her building up a good head.
