I have a right front air bag fitting leaking but how do you remove the air line from the top of the air bag? Do I have to turn the compressor off or and special procedure I have to do before I remove the line and see what's leaking?

 

no, just push on the fitting and pull the hose out. it will deflate. You might want to check all the bags for leaks as they usually leak together. If they are all cracked you need new bags on all four. Otherwise it will kill the compressor.

 

Be careful removing any air line that is under pressure. Normal operating range is 40-80psi depending on height setting.

If you do not have access to a diagnostics tool to deflate the system completely, I'd suggest the following:

1. lower the car to access mode to minimise pressure in the air springs
2. place a trolley jack under the radiator box frame and lift the car slightly so the front weight is on the jack. This will stop it from dropping suddenly when you remove the air line. Put another jack under the rear if you are working on the rear too.
3. wear gloves and safety glasses.
4. make sure body parts, loved ones and pets are clear of the car. It might drop despite actions done in step 2.
5. on the front air spring (left or right) grab the air line at the top of the spring firmly, depress the collet towards the spring and use a gentle up-down rocking motion to ease the air line out of the collet.
6. close your mouth and try to avoid swearing when the line does come out.

Replacing the front bags is a piece of cake... 2 fiddly clips at the top and a pin held in by a bolt at the bottom. If you have "plus size" hands, you may want to remove the inner wheel arches to make it easier to get at the top clips.

Rear bags are simpler again... R-clip at top and bottom, but the air line is best removed by using a long blade flat-head screwdriver (to push collet) and long-nose pliers to push-pull the air line.

Safest way to deflate the EAS is using a tool like Storey Wilson's EAS Unlock Suite (free but you should donate) or a Nanocom Evolution.

I still seem to have a leak at the right rear bag, over night it sags down just in that one corner. I sprayed soapy water on the right rear air line fitting just over the frame rail and didn't find any leak. Is that another fitting directly on top of the bag like in the front two bags?

 

Nope, that collet fitting in the gap above the chassis rail is the only line in/out of the rear bags.

If you have also confirmed that the air lines/collet fittings going in to the valve block in the engine bay are not leaking then the issue is most likely to be a leak in the solenoid itself. Easily fixed with an EAS O-ring repair kit, about $30 off eBay and follow my rebuild guide at http://paulp38a.com/99p38a/eas-valve-block-renew/

Cheers, Paul.

 

Yeah it probably is the solenoid that's leaking, because there are no leaks from any fitting even on the side of the valve block. All the bags and shocks have been replaced already right front the land rover dealer. I bought this for $1000 and found $4000 of work done at the dealer in the last year. The replaced the air bags, shocks, compressor and dryer. Also the fuse box and a few outstanding recalls.
