I have a 2005 e500 with some serious airmatic issues... and I am pulling my hair out. The car has had both rear air bags, air pump, and airmatic computer replace and it still has the same issues...

here are the codes that keep coming back

5340 y54/1 (airmatic valve unit, right rear suspension strut) y54/1y2 (level valve) : open circuit

5350 A9/1y1 (airmaitc pressure release valve) open circuit

5390 Y54/1 (airmatic valve unit, right rear suspension strut) y54/1y1 (additional volume valve) : open circuit



The only thing I can get the car to do i pump up the left side. The right side wont do anything. And when the left side pumps up it pumps all the way up.. The old air pump did sound like crap and the new air pump sounds MUCH healthier. I am seriously stuck and don't want to have to bring it to benz so they can tell me I need to replace the entire system. I guess thats why they love to replace the whole system since they themselves dont even want to take the time to properly diagnose it..

I am losing it! If anyone has ever dealt with this issue before I would love to hear about it!

Has the air distribution valve been looked at?
This is downstream of the pump and sends air to all 4 or whichever corner needs it.
These and the connections can develop leaks over time.

Revisit electrical connection/harness to right rear.
