Airmatic question

Hi Members,

Need help!

Airmatic malfunction?

Heard hissing noise from left rear wheel - found big cut in air spring. I went ahead and got Arnott air springs and had indy replace both rear air springs. After install he said need to change compressor as it did not fire up so replaced compressor (also Arnott). Now the car still shows airmatic malfunction. the raise button raises the car but does not lower it.

Also what the factory recommended height setting for airshocks - indy set at -40mm at all 4 corners but seems low to me and ride quality is ****.

thanks

Valve block. You probably did not need a compressor. That's my guess.

sensors do not go bad that easily, start by getting the vehicle recalibrated.and an actuation test.

Be prepared with parts. Mine would not recalibrate so that is why I am replacing the valve block.
