EAS The Battle Continues

I have a rear right sensor that is bad and I know this by watching it in live output. With the Rangie in level ground, not moving, I see some small sensor fluctuations (+2,-2) that shouldn't be there. You could try this on yours.
 
Took her for a very long drive, everything worked, went through loads of floods. Really enjoyed it! Just the slooooooooooowly to rise issue. Once at normal height, it can go up and down like a yo yo!

Yep, agree..... Defo the symptom. Just can't find it!

NRV1 itself, O'rings in block to main block that NRVs sit in. Violet pipe connection into block. Pipe itself or it's connection to tank or tank itself, leaking joint on pressure switch. That is it, cannot be anything else.

Thanks Wammers. I soap spray tested the tank connection and the big bolt on the tank. And all the connections into my new valve block. No leaks I could see. I am worried now my new valve block may have a faulty NRV.

I ran engine at height, switched off. Waited for a few mins. Removed the exhaust and there was a very very tiny air leak. Could hardly feel it or hear it, could easily stop it, but it was there. Does that mean the NRV has gone already? If so, how do I fix that? Jeeeeeeze!

As explained in my "How to" you will have to wait some time if it is the NRV to build pressure. 140 PSI is a lot harder to stop than 60 PSI from a bag is. If it's a slow leak it will take time to build. So there is every chance, as you say the suspension does not drop over a good length of time, that the air you feel is from NRV1. Is it a new block or rebuilt by some one. If they have used red O'rings on the NRVs that could be the problem. They need to be stiffer black ones. Red are ok everywhere else but too soft for NRVs if there is any wear on the nose guide and the NRV can wobble about as it engages more so.

Thanks Wammers. The valve block is brand new, not reconditioned. Hmmm tricky!
 
If the block is new, sounds like it's been stood on shelf for a long time and the O rings have gone hard. NRV's are in the bit screwed to the eng of the main block. Easy to access. If. you bought it as new, I'd demand a refund.

I'll run the test one more time to make sure.....can I just check from the HOW TO...

a) Raise car to height
b) Wait 5 minutes
c) Remove Exhaust.....any air comes out.....buggered??

Thanks
 
Well, sort of good news....!!:rolleyes:

Ran car, raised it to standard height........switched off, waited 5 minutes, removed exhuast.....No air at all coming out. So NRV ok right?

Also this morning, hit standard height and up she went, straight away!!!

Went around with the soap.........no leaks anywhere....(that I could see).

So, just for interest.....when I raise to standard height....pump comes on for 15 seconds, clicks off.....valve clicks a bit front moves around abit....pump clicks on longer, clicks off.....front dances a little more, pump clicks on for a while...then clicks off. On flat ground.

I suspected that I had two issues, an air leak on the storage side (as Wammers has said, and I agree....but can't seem to find it, and today not presenting itself at all!!) and the dance, dancing and a tiny lift with pump running after a rise to height (air bags are NOT leaking).

Anyways, front sensors on order....may eliminate the dance....as my sensors are 12 years old and one did have a fault until I swopped it over.

The saga continues.......
