Air suspension fault

Dbonnick11 · Friday at 21:56

I’ve recently brought a 2006 L322 and it’s coming up with suspension fault when driving sometimes but no obvious issues/ change.
Came out to the car in the morning and the rear was on the floor. First thought was air leak but then 2 days later it hadn’t dropped overnight, luckily I’m a mechanic so plugged it into the diagnostic machine and nothing came up so I am stuck, was wondering could it be the valve block sticking every now and then ? Many thanks in advance

It's got to be something unmonitered and possibly uncontrolled to an extent.
So youve got no faults at all

What diag are you using

+1 on this, some diagnostic will say they will work and even list EAS module but won't actually communicate or only partially.
I tried a friend's diag and saw exactly this

Leaks open and close where the bags fold.

I would check the compressor output.

Got a feeling there might be 2 different brands used in the L322?

I did wonder if this could be the case but the bags don’t look too old and It was only extended for a bit of a muddy field and then stays in normal height when it became deflated but couple days later it stopped deflating

Totally new to RR/LR stuff, where is the compressor on the L322

Never played with one but I think it is under the spare wheel?

If it isn't there then it will probably be under the car behind the rear wheel on the left (near-side in the UK).

When I say spare wheel, I mean inside the car. As in take the spare wheel out and look underneath it. Or is the spare wheel accessed from underneath?

There's a thing from JLR called Topix which is a sort of online version of RAVE, the workshop manual. RAVE might even cover the early L322. Worth a look.

On mine (facelift) it's under the spare wheel in the boot

It's under the spar wheel in the boot which is inclined to fill with water.
