07 E550 Airmatic Issues After Aligment
So I figured I should get my front end aligned it was a bit off steering a tad to the right. Take it to the shop said and done I leave and it says malfunction with the arrow pointing up. I see no issues the car is not lowering at all and drives perfectly fine. So I take it back to him he resets it and the next day this time it comes back on. Again no issues as far as driving just the malfunction turn on with the car showing and the arrow pointing up. This issue never came up before.
UPDATE:
It's code A9/1Y1 AIRMATIC PRESSURE RELEASE VALVE OPEN CIRCUIT. This has to be very very coincidental because this code only appeared after taking it from the alignment shop. He swears he has touched nothing other then a couple of bolts. So I don't get how it just comes on other then pure bad luck. Thank goodness it doesn't cause the air to leak out or else I would've been stranded. Can just the valve be replaced?

I did not. It just randomly appeared. The only thing that it could possibly be was we had a streak of sub zero temperatures when it popped. Other than that, just completely random. Comes up every time I drive the car now though. But no ill effects.

A9/1Y1 AIRMATIC PRESSURE RELEASE VALVE OPEN CIRCUIT
For that code, check the wiring harness to the air compressor.
Sometimes those can break.
You'll have to take the plastic covers underneath the car to access it.
The valve itself is hard to find, better find a new or reman unit if wiring isn't broken.

i opened it up a couple of days ago looked at all the wires i pulled and pushed on the connector and any fitting that goes to it and found nothing odd. So new unit is probably in order.

OK, just wanted to update here. I got the malfunction message again on the way to work, but this time by the time I got to work the car was slammed. It wouldnt raise or lower at all until I shut the car off, then turned it back on. Pump kicked on and aired everything back up to ride height just fine. Little confused as I still cannot get an active code on the scanner.
*edit* Just went out and checked it again just now (some 4 hours later) and it hasnt dropped at all. Leading me to believe its not the system itself, but maybe could be the valve block? Ill try again to pull codes when I get home from work in the morning and see if anything comes up yet.
@karpetcm any updates on yours?

Ok, now the pump kicks on for a second and runs then shuts off and I get the error. I cleared all codes and a 5508 came back which says "The pressure line system leak" Yet the system appears to hold air. Ill see tonight when I head out if its lowered at all. (code is from an icarsoft MB II so not sure if thats the same code as star or not)

Atleast you got a legit code off it. I still haven't taken mine to the mechanic shop yet with the better scanner. Hoping mine doesn't get much worse till then.

I can get the pump to run by clearing the code and then restarting the car. It will run fine until the next key cycle and then give me the 5508. I replaced the pump two years ago, but wondering if it isnt on the way out again. It sounds pretty weak. But I also get an almost immediate loss of pressure when monitoring the pressure sensor. I can watch it from from 2.6 bar to 0 in 5 or 6 seconds time.

And drove around today just fine. Error and all. Tonight about 3/4 of the way to work and it gives me the message and the car was bouncy as hell. Got to work and the bags are empty (rear bags for sure, front looks low but not bottomed)
*edit* and now just went out and checked and its all on the ground. I can hear the pump run for a few seconds and then it times out. Car doesnt move at all. Im guessing its got to be the valve block (rear bags are arnotts that I did a couple of years ago, so no rear air chambers) but for both the front and rear to have dropped, I would almost assume its the block.
Ill have to have it towed to my parents in the morning (I dont have a garage at my place) and do some investigating here this week.

Just wanted to give a small update on this. I ended up getting it to pump up and drove it out to my dads shop. It was low again by the time I got there (8 miles or so). But let the car run and it aired back up and has been sitting fine at that level since I dropped it off on the 18th. I plan to replace the valve block here this coming week when the parts come in. Im hoping thats the issue.

With my recent airmatic issues including erratic behavior like you're experiencing as well as the same error codes, my issue ended up being the pump itself. It was leaking periodically would drop the car all the way down sometimes, then other times it would raise and hold air. Eventually, the car bottomed out and the pump wouldn't lift it at all. Anyway, check the pump also.

There's always a chance that you have a slow leak somewhere in a strut or something that was causing the pump to run more often than usual which wore it out in two years. A good pump can keep things going for a while but it's just not designed to run that often so it will eventually kill it. I think my issue was my rear bags which I also replaced this time. Just did the fronts when I did the pump 2 years ago.

Im not sure about the OP, but mine ended up being the hose between the pump and the valve block. It had worn a hole in it and was leaking. The wires to the pump had also rubbed and wore through the protective sheath. I replaced the pump, tubing and added protection to the wiring. Working good as ever.
