Swapped OEM Air Springs for Arnotts- Not Filling
I have searched and read far and wide, looking for any additional ideas.
Prior to this install the car would raise as lower as normal. Ride height was lowered via STAR however the “raise vehicle” button and compressor worked fine. My only issue was the rear and failing to maintain ride height when parked for more than a few days. When I removed the stock bags the rear passenger side was damaged and barely held any air. As suggested by Arnott both air springs were replaced at the same time.
I did the swap using the FCPEuro video as guidance and everything went perfectly. I have triple checked my Voss fitting and electrical connections and everything is fine. The compressor still kicks on and raises the front of the car but I am getting zero air to the rear springs.
I have lowered the car to slightly below ride height, supported by a jack, unplugged the battery to reset things, and when I fire everything back up I still get nothing at the rear bags, no hissing no inflation.
I have contacted both of my local Indy’s and they said they have to see the car to do anything.
Could this be the result of the car being lowered via STAR prior to the swap? Could I have damaged the ride height sensor somehow?
I appreciate any feedback.

with proper diagnostic tool, you should be able to actuate each valve and monitor its status. can't troubleshoot without looking at electronics for functional testing.

Did you do the lowering via STAR, or a shop? If you did and have a STAR system that is the first step, checking those values and forcing each corner to add air. If you don't see if you can find someone who does - where are you located?
I can't see how the modified values would affect refill like this, all it is is a little trickery in the level sensor baseline. The rears share one sensor, I think the fronts each have one, so you could have a sensor issue since both rears aren't inflating, but you won't know for sure until you see its value in STAR.
I'll be following this thread, I'm also lowered via STAR and need to replace my rear bags soon, I just keep putting it off...

No fear, just laziness 
. I have a lift at home, and STAR, wish I was closer and could help!
You probably checked, but I'd just make sure the rear level sensor was reinstalled in the correct orientation (and plugged in).

The single rear level sensor on the E55 is near the rear diff. I didn’t mess with it during install and a visual inspection today looks fine. Do you think there’s some way it got tweaked during this install?

I had the same issue with my 07 when I did the back air bags about 3 yrs. ago. I replaced back air bags with Airnotts and when I first started the car, the front rose but the back didn't. I pushed the raise car button and the entire car rose to its full height and when pushed again it lowered to its ride height and everything worked.
You might give it a try if you haven't yet.

I’ve tried that several times with no luck. No hissing at the bags and no error messages. Did you have the car on the ground at that point or in the air? I read in an old thread somewhere that when the bags were disconnected the car may have thought there was a leak and now it won’t send air to the rear. I need to somehow reset that if it’s the case.
