Hi there quite new on here but have learnt a lot and love the forum but I do have a problem with my a4 avant 170
When in the higher gears 4-6 around 1600-2200rpm if I put my foot down to accelerate the car judders like mad and won't accelerate, if I lift my foot then put it back down but light pressure the car will accelerate but not foot down, if I leave my foot hard down the car just accelerates but feels strangled from power nothing like a 170 should like something is holding it back. I have gave it a full service myself and stripped and cleaned the inlet manifold and egr valve and replaced actuator on front of manifold, there are no warning lights on dash so no point scanning for faults. Not sure if it could be a boost leak as car will accelerate fine if I wait till about 2700rpm and then put foot down turbo kicks in fine, there is also no smoke or no smells I can tell of.
Many thanks for the help :-)
