I have a 05 2.0tdi B7 153km 6 speed i have noticed the power through the revs is not very smooth especially when engine reaches temp and some time it will shudder or jerk as the turbo kicks in just seems to be down on power until it hits the turbo but o/all not smooth in any gear. when the car is cold it starts no prob first turn and everything is perfect all the problems seem to happen at running temp slower to start etc. has anyone come accross this before
