different air suspension pain 4.8is

[sockethead]

Believe me, if you are getting an accumulator fill error, you need a compressor. My GF is a service advisor at a BMW dealer so we have access to techs and equipment. They couldn't figure it out either. The system passed all tests every time. I have a GT1 and tested myself too. They thought compressor might be the cause but it wasn't until another member here said that replacing the compressor on his X5 got rid of that error, did I have conformation that was the problem. Sure enough when we replaced the compressor, the error went away.
You can drive the way it is and the system will function somewhat normally, we did for months but ultimately you probably need a compressor... Good luck!

BTW, there is a PDF floating around somewhere that explains how the system works in great detail and once you get a GT1 setup, DIS also explains how the system works when you run the tests.

Ok you bags hold air because of the way they are. Look on Arnotts website. It is like a sleeve rolled on itself. Just the way it is inflated, could be pressing on your leak, and sealing it somewhat. I say somewhat because you clearly have a leak, and your compressor has now disabled your ride control and self leveling. All it does now is keep inflating your bags, but not letting air out to level anything.

and i'm the one who had the "EHC 74 Accumulator Filling Requested pressure remains constant" error whose car was perfectly fine, once I replaced the leaking bags that was my only fault.

Replaced my compressor and no faults and air suspension operates as it should, ride height control works, etc.

If your car is sagging you have leaking bags, replace the pair (front or rear) and replace your compressor if you get the error I mentioned above.

Sucks, and its pricey, but its the only way.


sockethead, you were the one who popped in on my thread a few months back right? glad to hear my findings helped another member if thats the case.

Bnagy, I also read your earlier posts and believe me when I tell you that if the shop did a leak test and found your struts are leaking, although a tiny one, it still is a leak, and it will only get worse over time.

Don't waste money on a compressor now, to have the leak burn out the new compressor and you will still have leaky struts.

Arnott sells the Reman air struts for 369 each which you can replace yourself if you are handy (you send back your leaking struts as core), and 510 for the compressor.


For anyone else chiming in on this thread, if you have any sagging, you have leaks. Replace the bags that leak, and replace in pairs. If you have the error I listed in my previous post about accumulator filling and pressure remains constant then your compressor is out of usable specs and is "burnt out" and will not function correctly without errors.

4.8MNSTR had this Problem..found out it was the "Blue" box underneath the cargo area malfunctioned ....so what he did...he ended up using a Separate Air Management system where you can adjust the height at Any speed your driving using his existing bags.......cost was $2k with pancake air tank plus other accessories i guess if you want.........
here is a vid of his X5 4.8MNSTR
his vid is minute 8:00-9:00 marker.............

You can also convert to springs. I found out that you can remove the SLS from your Vehicle Order (VO) with NCS expert. Ha. I wouldn't do it though. Why lose a feature that actually makes the X5 drive-able on NYC streets.

we only gotta find a way to """Inactive Suspension"".....
and yes you can Adjust the Ride height at any level as you can adjust it through Digital Meter...which is I am looking into investing this type of feature down the road instead of lowering it...ill jjust go this route and put two bags infront...
