    Euro S50 strange noise

    Went on a short drive yesterday and then a strange noise appeared. At first i thought my fans are acting up, but it was too cold to need fans.
    When i stopped then fans weren't even running.


    There's this noise like some overpressure valve that's vibrating?



    Sorry for the shitty vertical video, it's the sound that counts. Note, the fans started running, but are the background sound, it's the main weeee-woooo sound. It was a recurring sound, always weee-wooo in the same manner as in the video.

    It had power, it ran great and after i restarted it the sound was gone.


    Did this come from the VANOS?

    I drove a few miles today and couldn't reproduce it.
