what Hesitation Issue are you Having ?


"Hesitation" on a 1.8t - depending when it happens i.e RPM/throttle position - if it's immediate upon opening the throttle - i'd suggest Spark Plug Gap.... or even Fuel Filter Separation Issues - If it's happening after being open throttle for a bit - both of these still need considering - but also the Electronic Boost Control Solenoid (Pierburg) and Vac hose Connections to from this.
