Hi, I have a 2003 Range Rover L322. I had the suspension done in Leatherhead by a ‘reputable’ jag/Range Rover specialist. It failed soon after and I had then moved to Lands End, and since has sat rather sad in the drive. I did have a local garage guy look at it who suggested that water in the boot had been sucked into the system and emptied the boot of water. The pump was still working. Will the brand new air bags be full of water? Will the system need to be replaced throughout? I’m no mechanic and lack tools but I think it’s too good to scrap. It has 120k on the clock and has had the whole turbo system replaced as it blew a while back. It still starts first time when the battery is charged and connected. Any help appreciated.
 
Are there any signs of a large amount of water in the boot wheel well?
If it was me I'd be checking the pump to see if it is full of water. I haven't played with the pump yet but I believe there is an air dryer which I guess would be dripping with water if it has gone through the pump.
I suspect the reservoir would also be full of water.

Same Wabco pump is used on many vehicles. X8R have a video showing how to refurb it.

If its the original pump its likely to be Hitachi, Similar but not interchangeable without diagnostics upgrade.

As has been said get a look at it and the watermark;).

The water would have to be a good couple of inches:eek:.
You need to get the cover off and look:).
If the pump still runs then something else is going on, so diagnostic's is the only real way forward.
when it was "fixed" first time what was done?

I had it in a local garage and he drained the boot as there was a lot of water in there. I’m thinking it might need the suspension system to be all taken apart and cleaned with possibly new parts. He said the pump is still working but the suspension doesn’t lift at all. How difficult is it to strip it down and replace or clean the parts?

Hi, the system was stripped down and the front air suspension bags were replaced with genuine Rover parts. It worked fine for about 4 weeks then started to fail when I moved house 290 miles from the garage! I rand them but he just didn’t want to know.

As Marjon said, diagnostics are the only way forward unless you really want to spend a fortune stripping down things that may not need to be touched. The compressor may run, but does it produce any pressure? Diagnostics will tell you.
 
As said diagnostics are the way to go but that won't get rid of water. If you are handy with spanners then I'd say you'll need to take a few things off and see if they have water in them.
These are all the suspension components so anything connected to the pump via an air line as well as the pump itself.

Is there a diagnostics tool I can use on it that I can do myself or should I just get it done at a specialist?
