    Guys.

    Had a custom exhaust built for my S3 and the flaps never worked after which seemed common.

    I bought the AWE remote so that I could get the valves working.

    They have been installed but when you press on, the valves open and shut continuously and doesn’t stay open.

    Long shot but does anyone have a clue at why this is happening?

    I will assume the vacuum isn't being held to open the valves - maybe the spring on the valve is too strong for the vacuum to hold or the vacuum unit may be failing

    I am not 100% sure the mechanics of it all but that's my opinion

    I think the valves are electronic not vaccunm. That’s what I believe anyway
