The left rear drops with the fuse pulled, whereas before the front end would drop, both sides. I removed and cleaned all three valve blocks, now after the compressor replacement only the left rear drops and I saw bubbles at the fitting so I replaced the fitting, still drops. maybe the bubbles were from the spring and not the fitting but were coming up from the fitting area?

 

Per the png's, there are two, one showing an O ring at the top of the air spring. It might be leaking there and appear to be the Voss connector.

Air bubbles are a good sign; the trick is just to figure out where the leak really is.

 

Ok so its not leaking from the voss connector lol
its actually leaking from the valve block...FROM THE PLUG ITSELF!!! crazy, it wasn't snapped in, now its not leaking. we will see overnight

 

Perhaps success - but let us not get too pleased, just yet.

This will all look easy compared to if the electric HVAC air doors start acting up - now that is a challenge.

We appreciate you keeping up informed as to the progress and challenges.

It helps all of us.

 

Ok, so this morning it is yet again sitting on the bump stop left rear, and the left front has sagged (this may just be due to the rear?). I am getting very annoyed.

 

The F26E fuse was pulled so that is not the auto level system letting the air out of the left rear. As such, we can conclude there is a mechanical leak somewhere in the system.

I say somewhere, as another person had a somewhat similar problem but it was a combination of a leaking air tank and leaking block valve orifice related to the respective air spring.

The link below is to some Voss fittings and 6mm tees. You may wish to remove the left rear air line where it inserts into the rear block valve, then with Voss fittings plug off air line from the air spring and also the opening in the block valve. You will have to purchase a 6mm tee as well re the air spring line as you will have to be able to pump up that air spring from a shop air compressor to say 140 psig or whatever it takes to get all sort of level.

Then you wait again and see if the left rear corner deflates. If it does, then if is something related to the air spring or line; if not, then the leak is elsewhere in the system.

Check that plug again - it may still be leaking there as the reason for a leak there may not be as simple as one might have first thought.

 

This is the link to the other thread on the air system that shows metal tees in place and the Voss fittings.

not leaking from the plug...

 

Took the valve off and cleaned it again, let's see what happens.
