He used to be that they would area and then I can keep it up and it would not leak now completely Sam’s and won’t even lift up past to his sound my driver side used to air up but it doesn’t even go up now I replaced the triangle I guess module in the back that distributes the air I replaced the pump should I replace the computer also The front no longer goes back to normal position it just stays in the elevated position also .

Airmatic bag are going bad.
Hi,
My rear suspension is about half an inch lower on rear passenger side than on rear driver side. I've look around today with soap and water, seems to me there is no leak is the hoses or anywhere. Anybody knows how to set or reset rear stabilising unit electronics ?
When I wake up every morning, the passenger rear side suspension is completely dropped. When I start the engine, it comes up in about 30 seconds.
Anyone has an idea what this can be ?
Thanks very much !

The trouble with troubleshooting is that all you can normally see is outer shields. When cracks on them indicate aging, there is no easy way to tell when the bag is bad.
Good scanner will have option of inflating 1 bag at the time, so giving it time you can see when it goes down.

2006 E350 Wagon
I know this is an old thread but maybe someone will answer.....
I have a 2006 E350 wagon which drives perfectly.
Yesterday i noticed that the passenger side, especially the rear, is very low...much lower than the driver side but the wheel is not touching anything and it still drives just like normal.
But looking at it I am not very happy.
1- Is it safe to drive, and if so...
2- I am due for an inspection and would it pass if it is driving normally despite one side lower than the other?

Hello,
You do have a leak somewhere, this situation means that there is a leak and it is most likely the air bag, they are smaller then the front. If don't replace it, eventually your pump will go.
I almost guarantee it's the airbag. Have done any work to the suspension? If not its going to be the rear air shock.
I will look in the shop tomorrow, i might have one.

I took a quick read through this thread. Everyone is going after the air bladders or the computer. I think there's an idea that I haven't seen mentioned. The rear end height sensor is attached to the rear swaybar. If you have one or both rear sway bar links with bad bushings or broken, it has no possibility to level properly. All the rear link bushings are also important. Rear subframe bushings could be bad as well.
The sway bar bushings going bad could be responsible as well.

E350 4matic
Hi all, my 2006 e350 wagon with rear air suspension only is tilting to one side. The passenger side sits 1/2 inch lower than the driver side. This problem still persists after replacing both rear air springs with new arnott parts. So I am at a loss as to what to do. Any insight from you guys?

E-350 - Wagon - 2008
This may be a NB and a stupid question.
I have the same problem, my 2008 E350 Wagon is leaking air from rear leveling suspension. And during cold winter months, it lowers (mostly on the right side).
Not sure where there is a leak, but there IS a leak.
Can I just add a bit of stop leak fluid into the system?
Something like ATP-205 that typically seals rubber hoses and o-rings.
This:
Would this work?
If so, where (in this system) would I add the fluid.
If so, are there any problems that it can cause?
Has anyone tried this? Sounds like a no-brainer but I am sure there must be a reason no one has suggested it yet.
Thanks

Thanks for these instructions.
So, you are saying that the place to check is under the back seats.
Doesn't this assume that the leak is NOT in the airbag/airspring?
Since only one side is tilting, my sense is that the compressor (and the rest of central control) are okay.
With that said, if left for a while, both sides become low.
Let me know your thoughts please.

did you figure out the cause?? I also am hearing a clicking sound now in the back rear when pumping up as well as deflating, but it’s never slammed to the ground or anything
