I've set them all at height. 5 inch at the rears & 6 inch at the fronts. I'll measure again tomorrow...

Meanwhile, pump ran fine when I jumped the relay. But, is it supposed to run with the engine on & relay replaced while on EAS fault? The car was sitting low down, but i had the front door and the tailgate open at the time

Confused.

I cant get her on diagnosis until Hamish is back off holiday So no diagnosis done. I fired her up, bridged the relay and the pump ran fine. However, I was confused to hear it STILL running with the relay replaced! As stated, doors open. Is that a problem? Not a problem. the pump will run even with the doors open. I often let mine run for a while with the doors open to get some air in the tank if I know it's fully depressurised. I don't think it makes much difference but at least when you close the door, you can see it moving instead of it creeping up ever so slowly.

Looking out the window, she looks to be in the same position as I left her last night. So I can only imagine there are no leaks at the air bags. What does the relay look like under the seat, a standard yellow or green as under the bonnet? And why do you suppose the car may be lowering only while it's being driven? What are nose cones?? I think the lowering whilst driving is either a duff sensor (Unlikely as I think you said you'd replaced them) or the heights being set too close to the accepted range. If you then go around a bend it drops outside the "normal range" and the ECU thinks, "Hmm that's not right, I best use my defaults" Mine was doing that after I had new airbags fitted as he set them all too high. Looking at how you're setting them as 5 inches or whatever it was, I'm guessing you're measuring from the top of the tyre to the wheel arch? You should be measuring from the centre of the wheel to the wheelarch if you're doing it without blocks. That way, the tyres have no effect. When I got mine back after the new bags were fitted, it was all over the place so, not having any blocks, I used the measurement method and it got me close enough to stop it bouncing all over. The required measurements are in @wammers how to in the tech archive.
Nose cones are the cones on the end of the NRV's (Non return valves) in the valve block.

Sorry to sound a bit thick I guess I should have inserted my one ways directly to the pipes, bypassing the Tee pieces, but it seemed the right thing to do at the time Yep, using manual valves tee'd into the system still allows the system to control the bags. Even in fault mode, mine was trying to level it. It wouldn't add air but if the corners had a much different reading when I stopped, the other 3 would drop to the same level. Eventually it would be on the stops until I cleared the fault, then it would go back to the settings I asked for.

I have two laptops with good batteries, that's because they're win 10 and barely get used Hateful things. I have a win 7 and a forty metre extension cable though

Ok, I found a relay under passenger seat. Quite tall, black, 6 pins (one small) and it has the following printed on it: Land Rover, TRW, Rover P/No ANR 4652. TRW P/No 5160600A. Then I assume date built 39/99.

The nose cones are on the end of the solenoids that open to let air into or out of the bags inside the valve block.

Yeah, I had T pieces originally and with all my initial hassles discovered they were leaking and causing half my issues!

I can categorically state that these Tee pieces have not let any air go. I drove at 70mph along the dual carriageway to the gig and she sat beautifully (this was after inflating them the night before). I removed that relay, re inflated (after the kerb carry on) and drove home at the same speed, emptied the car, parked up and she's still the same height so I am certain they are as they should be. I would bloody hope so at the price I paid for the lot. They are good for 10 bar apparently (which means likely 15 at a push) and used in food processing and what not.

Anyway, I am sure it was just the pump at fault as she always stayed put. The last few weeks she was getting slower and slower to rise (I know how she feels) so I think the issue was the worn out seal. I am guessing the valves may not be too long behind though

No, sounds like you're right and it is the compressor seal. Have you replaced it yet? If so and it just isn't running then it sounds like the thermal switch is cooked. Not expensive but a bit fiddly. Or talk to KurtJohnson.

You can have a T in the line to the tank and stick a little pressure guage on it. Compressor keeps it somewhere between 120 and 140 psi on mine.

The pump runs fine with the relay bridged. It also runs with the relay replaced, but I have the EAS fault showing on the dash. I pulled the relay to stop the pump as well as the relay under the passenger seat to stop the drop. I always thought the rear drivers side sat a little low, so will get that addressed when I get the fault reset.

Send a message to Datatek on here. For a few notes he will post a lead and everything you'll ever need to diagnose the EAS.
