S320 cdi 2006 air suspension

Hello all,
The air suspension is not working, have removed compressor and tested works fine, but on car is not being activated. Any one any ideas what problem may be.

You need to get the car plugged into star and follow the tests on there, it will test the different items on the system,

You say the pump works but I bet its not up to spec, one test shows the pump out put, my money is on the pump......
