Discovery LR5 Air Suspension Issue

[jruvira]

Hello all, I could use a little help

I have an LR5 that all of a sudden the suspension will not raise the vehicle. After doing a little searching here I found a thread that talks about the possibility of the suspension compressor not working. I looked on you tube and found an amazing video of a mechanic showing you how to replace the compressor here is the link

I took out the compressor and drilled out the rivets from the cover so that the compressor was exposed, I put back the compressor and conected it and turned on the rover. I immediately saw what the issue was. The culprit is the Dryer Valve when the compressor turned on you could see and hear a massive air leak through the Dryer Valve. You do not have to buy the entire compressor, you can simply purchase the Dryer Valve, remove the rivets and reinstall it. Cost was $75 on amazon this is the part number from Land Rover LR140035.

So I reinstalled everything turned on the Rover and the it started to fill the lines with air and the suspension raised the Rover.

The issue that I am having is that the compressor keeps on pushing air through the line and the air attachment point snaps off and the SUV goes down again.

Is this happening because the computer needs to be reset and it is not recognizing sufficient air in the lines?

Any help will be greatly appreciated. THX

I have attached the images of my compressor opened and also of the leak you can clearly see it. I also attached images of the parts diagram and Dryer Unit

Is the air line blowing off the drier fitting?
If so, you will need a new air line connector fitting.

Yes it’s the fitting that connects the compressor to the air line. It keeps snapping off, but I don’t see the compressor stopping does it need to reach a certain pressure point to stop? Thx

I attached an image and circled in red.

The compressor does stop when the desired pressure is reached.
If that fitting is leaking, the compressor will keep running.

If you need the fitting, I can send you one. Free.

The fitting wasn’t leaking it was snapping off as pressure increased. I assume those plastic threads ware off and the fitting being tight gets compromised.

Can you post a picture of the fitting, after it broke off?

 

[jruvira]

Apologies for the delay. As you can see the only way it would stay attached is with the draw-ties.

You will need a new fitting.
Don't take apart the new fitting and make sure the tubing is inserted all the way in.
