Hi all. I have replaced both air springs on the back of my Disco 2. One last year and one in 2013. So I don't think they are the culprit as the back end goes down evenly in about 1 hour. It pumps up OK, usually I would just change the air springs but Ive only done about 3000 miles since 2013. I 'think' I can hear air coming out of the compressor housing, there is a vague sort of clicking noise from it with the ignition off. Can anyone suggest some key things to look at? Is it easy to drop it all / remove it to examine? Thanks for any pointers.

Hi Have a look at this,

Another thing you can do is buy isolation valves to remove the possibility of it being bags / pipes .

Cheers

Yeah I have read that a few timesalready Neilly ta! Looking at it again, it may be the 2013 spring. Seems a bit early to fail but the drivers side is defo more down than the other. I might just bite the bullet and fit a spring there to rule it out. I'm getting the hang of fitting these air springs now...

I think these are worth looking at , to trouble shoot the problems.

Neilly, cheers for that link, pretty useful. In fact I have the culprit. I would not have believed it but it is the spring I fitted in 2013 that is leaking. Washing up liquid in spray bottle and there it was. I'm surprised it was that as I do hardly any mileage and none off road. But at least it is the spring so an easy fix. Phew! Cheers again.

I had a look at my compressor yesterday and one of the bolts fastening it is very tight so I left it and sprayed penetrating oil on it. I looked at the compressor I have bought from ebay and found the corresponding bolt snapped off in the thread. It might be difficult to remove as heat applied might melt the plastic housing.

New part will fail, that's why there's usually a guarantee period, and you have your statutory rights. Unfortunately new parts are designed to fail one day after the guarantee runs out, so yep, it looks like a new bag is needed.
The air bags are one of those things on the vehicle which many owners will advise you to change as a pair.
While you're in that area of the underneath, check the security and condition of the height sensors too.
