    Juddering problem in my GSi

    Moring folks,

    Over the past few days I've noticed that when my car is cold, there is a noticeable juddering when pulling away, or trying to accelerate.

    I notice it more when going up hills, you can feel the car surging, then falling away, usually from where the turbo would kick in onwards.

    Once its warmed up its fine, anyone got any ideas??

    Cheers!!

    Yep. The boost is electronically controled. When your car is cold, or not upto full opperating temp, when you put your foot down, and the boost kicks in, it backs itself off. I presume it's to stop you spinning the turbo up hard before the oil's all warmed up. I'd imagine all the turbos do it. Mine does anyhoo. It's funny to watch on the boost gauge as the needle keeps hopping up and down.
    Try to not drive it too hard before it's nice and warm.
