Recently purchased Audi A4 2010 with 147000km, has a juddering when accelerating, smooth in all other respects, I cleaned the mass air flow sensor, checked the spark and coil packs, one coil pack is a different design from the others and I am having trouble removing the third spark plug.

Any assistance would be appreciated
