    Cruise Control Fault (MQB)

    My cruise control has completely stopped working.

    The DIS acts as if there is no input from the CC stalk whatsoever...

    I have only one fault code; this comes back instantaneously after clearing it. Does anyone have any ideas as to what is wrong?

    Code:

    Is there any chance this is related to your steering wheel swap?

    I'm not at all convinced this belongs in Car Repair Support and am seriously tempted to merge this thread into that one.

    The engineering problems are likely insurmountable. It would be like proposing to land a rocket booster section on a barge floating in the middle of the ocean.

    Interesting.

    Looks like the car may have had a brain fart. After a drive, the cruise control has started working again and the fault code has cleared. The car must need driven if you've taken the squib apart?
