Rough Idle CTS???

    I have a A3 8l 1.8TQS and have lately been suffering a rough idle.

    Car has forge 008, n249 bypass done and PCV simplification and catch can installed.

    I have scanned with vagcom and there were no fault codes present.

    I have disconnected the CTS and the idle smooths out (steering wheel gear stick vibrations stop).

    Will this be a faulty CTS?

    Thanks in advance.
