slight judder / miss fire

[passat 130 tdi]

this was on my tdi passat before a remap , but now its more prominant , if i hold the throttle and back if off ever so slightly in any gear at any speed, its like the cars being starved of fuel , apply the lightest of touches again and the car is ok , Now could this be the MAF on the way out , or are there any other sensors that can fail . i regulally use millers sport 4 which cleans injectors etc so i rule them out . ANY IDEAS .

When was the fuel filter changed/checked? I was just told today that a slight judder when using the clutch is probably a failing flywheel!

thanks , clutch is fine ,car pulls to 80mph in 3rd. sticky turbo veins is the top suspect .
