    boosting problem

    05-07-2012 01:54 PM #1
    My gli boost spikes to 12 pounds and if you hold it the car bogs down and the turbo studders. Does anyone know what this could be? Or how it could be fixed.
    Nah...if it ain't below sea-level... It can always go lower...

    Sounds like it could be misfiring. Does the CEL flash?

    If it is that, then the cure would be new coil packs and plugs.

    Similar thing happened to me, this is what was wrong. Im never was able to pinpoint it, but it is almost back to normal now. Just waiting for my coilpack spacers for my TSI coils.

    Vacuum line going from boost guage splice to fuel rail was split
    Coilpacks/plugs were bad
    Upper Y pcv hose was cracked and leaking badly (causing most of the loss in boost)
