    Regarding my 2020 T680 Kenworth, I have noticed that the dump or lift function is not working when I press the corresponding button. Additionally, I have observed an occasional air leak from the bottom of the valve, which I have circled. Could you please advise whether the entire component needs replacement, or if there might be alternative solutions? Thank you for your assistance.

    Valve adds and exhausts air from the suspension as needed. As long as it's not a constant leak it's fine.

    What u have circled is the exhaust for the leveling valve. If it is leaking constantly out of that port then it can be replaced ..
