Any experience with ebay air suspension compressor?
Code 5400-The first thing you must do is swap relay KG, in the Eng. Comp. Fuse/Relay Box, with a similar color relay.
Code 5508-You must check for leaks in the pressure line system. That means under the veh. where the reservoir is located and at each and every strut.

One thing I noticed is when the compressor was running there was no air pumped to the system, which I know the compressor is not that strong but still there should have been some air in the system.
I feel like the valve block is not opening the valves..
I checked for leaks soap water but there is no air in the system to catch leaks.

If not, remove the two wire conn. Gray/White and Brown at the Airmatic Pump, A9/1m1, then apply 12v to the Gray/White wire and ground to the Brown wire. The pump should run, but DO NOT run it for more than 3- 5 seconds.

So it is not the compressor as you previously thought. Actuate the pump again and after things fail, immediately check for codes.
Also check the Reduction Valve.

No one instructed you to apply voltage to that valve. If you make a mistake I have to find the problem.
But what I do not appreciate is someone talking to me the way you did on the last post. Remember we are here to help each other.... anyways again thank you for your help. I will fix the problem and updated the post.
