    belt noise cold start

    I have an 04 TT 225q. The last couple days when it was cold I got a few seconds of what sounded like belt squealing after start up. Is this something to worry about? Thanks guys.

    This happened on my wife's car after i change the serpentine belts. It was because they needed to be tightened more.

    Not sure about your car...

    Eh who knows. I will keep an EAR on it. If it becomes more frequent I will have a closer look into the issue.

    2nd that, the tensioner does all the work, so you can't adjust the tension. I doubt the T/B would be making noise, unless the belt is starting to angle off one of the rollers or the cam.

    My timing belt was making noise right before the bearing seized in the idle roller.
    My serpentine belt was making noise right before the bearing seized in the tensioner.

    Of course it wasn't the actual belts that made noise but the bearings.
    The tensioner, would only make noise on cold days before the car had warmed up, until one day the tensioner roller just snapped completely off.
