    As I'm driving down the road air gauges go down to 100psi and compressor kicks in and brings it up to 125psi and then it cuts out and purges air dryer. This keeps on repeating every 2-3 minutes.
    I don't hear air leak anywhere. What could cause this?

    An air leak.
    Could be in the pressure sense line from the tank to the governor.
    Could be the range cylinder on the transmission.
    Could be a brake pot.
    Could be ....

    You can try to bypass it. At my Cascadia they took off the airlines and screwed them together. In and out was a perfect fit. So I made it to a shop that had a replacement. You can check it if it's really the air dryer before replacing it.
