    I have posted this in the A3 8 L section but i as this engine crosses into B6 would your advice too. Basically when the car is stone cold it has no real power like the turbo isn't working, then after 2 or 3 miles bang it's all ok, no codes at all vcds?

    What gives?

    Thanks
    Ian

    could be the oil viscosity been too thick not allowing the turbo to spool up properly

    mine is a bit sluggish for a mile or so if its really cold

    have you got the right grade of oil in too?

    To be fair engines need nursing from cold, I wouldnt be trying to make any real power before it has warmed up.
    On my old Ibiza Cupra (1.8T) boost and fueling was limited before it hit a certain temperature - it may be the same case here?

    My B6 is similar, when it's totally cold in the morning shifting gears is also a bit stiff so just drive gently for a while until the engine has had a little stretch. But I would suggest maybe you check your engine oil have you had a recent oil service or anything or has this problem just started?

    The Mr Muscle clean has so far sorted this problem out, it was a symptom of the sticky turbo vanes
