E500 rear suspension wont rise???
Hi, I am having an issue with the rear completely bottomed out. If I press the rise button the compressor turns on and the front rises slightly but the rear is bottomed out. The only message I have is airmatic visit workshop but it has been there for a faulty rear shock. I don't have the vehicle too low or any other dash messages.
My question is could it be the valve block beside the compressor or is it something else?
Also I believe there is 1 line going to the back and splitting to each bag. Could it be that splitter?
If anyone has an airline diagram it would help

That sounds like air leak if it happen overnight.
I have rear air only, but from what I see whole airmatic has single air connector that with Tees supply air to each air bag.
Each air bag has independent valve that adjust the height.
Compressor will run for predeterminated time and if the suspension will not rise, it will time out to avoid overheating. After couple of unsuccessful tries, the red message will display.
I install pressure gauge for easy troubleshooting. In your shoes you can get SD and troubleshooting it with it, or get soapy water in spray bottle and crawl under the car.
When was the last time you service the compressor?

Depends on your definition of "routine"
Not too many rubbing parts on cars last for 20 years without replacement.
The compressor is oil-less while pumping 160 psi every day, so I admire when that thing last for 10+ years without service.

I rebuild the compressor when I had signs of the troubles.
It turn out later I had pinhole in tubing, but even at the time I spend like $50 on rebuild parts, I felt way better.
At the same time I added pressure gauge line, so now troubleshooting is a breeze.
So even the compressor seem to work for 15 years on the system that did not have other failure, with current $17 for new ring and about $10 for filter, I think car deserve it every 10 years.
