I have posted this problem before. Now I think culprit is either right rear air compressor valve, or simply the seal with the right rear air pipe into the valve. There is a faint hissing noise that means air slowly escaping where pipe connects to valve.

Neither the left nor the right air pipe nuts snug up when tightening them. The nuts just keep turning as if the threads are stripped? Or is that normal? The central pipe from compressor is very snug in the valve.

The nuts on the air pipes have a little 'o' ring. Is there any other washer or anything else?

RAVE doesnt seem to have a close up diagram of the air pipe washers/etc. Maybe it is something as simple as a missing washer of some sort. Shall I just keep tightening it?

Advice appreciated.

 

Anyone?

 

My 2004 RR has been doing the same thing with the Right Rear Suspension side. Not sure what it could be, but we recently checked the voltage for the height-sensors for all four, and it indicated that there was more juice going into the left-front height sensor. In doing so, we concluded that the front height of my RR is not evenly set, which is causing the rear to also be a bit off balance by about 1/2 inch on the right rear side.

I recently replaced both front height sensors. My next move is to replace both rear sensors. Other than that, no codes came up besides the "Air Suspension Inactive" displayed, but we had the reset already. The airbags for all four are new, and the compressor is also new. Other than that, I'll have to check the air-lines eventually, but I doubt thats what's causing the rear right front sagging? If I can't find anything else besides that, upon replacing both rear height sensors, I will try to have the air-suspension system re-calibrated once again to set-it up to its default settings, if not look up what the normal settings are to see if that fixes the problem. Hope this helps.

I got my 2002 P38 for a song. The EAS was leaking. Being an engineer by trade the first thing I looked at was the service life of the air bags and lines.

1. The air bags (springs) have about an 80K lifespan. So you basically replace them with your tires or every other set of tires. Biggest mistake people make is trying to skip this vital maintenance. Even if you can't see a crack, all it takes is a pinhole to leak air.

2. O-rings are everywhere and none are synthetic. If you have sealed bags, the o-rings where the lines are attached need to be replaced at least every 60-80K. See point 3....

3. I bought an EAS rebuild kit from Rover renovations. I did not overhaul the EAS block but I replaced all the o-rings at each spring and each air line connection point. Every EAS fault went away and the ride height workes perfectly.

With the rebuild kit, I still found that the front left and rear right air bags were cracked. I replaced all 4 corners with Arnott gen 3 springs. It's now been 2 years without a fault or a leak. The workshop manual states that the air suspension left alone ( and as long as the leveling module doesn't go bonkers on a grade) you should lose less than an inch in 2 weeks.

 

I just replaced the airbags in my 03 RR, and placed the Arnott springs, and they are the best, as I am sure that you know. I got rid of that future problem in advance, my rear suspension on both sides was sitting like a low-rider, and thats not the look for a Range. Happy riding.

 

Check out the Rover Renovations site. They carry special sourced synthetic Bump stops. A REAL PITA to install but they are so robust they can double as a true "get you home" spring. I used to carry an extra front and rear spring for my deep desert runs. Now I can just strap one of the wood blocks I carry to the frame in a pinch to get home.
