I have a 08 IC C300 with a DT 466 egr engine with no low air buzzer . Lights work when air pressure drops . I replaced the buzzer and still no buzzer . Could it be the circuit board or could something else be wrong ?

Did you get the correct buzzer? I believe there are a few different part numbers for those buzzers and they don't interchange.
