I have a 2007 Audi A4 2.0T with an FSI engine. Codes P0300, P0302 and P0304 pop up indicating a misfire on cylinders 2 and 4. I replaced all spark plugs and all ignition coils and have even moved ignition coils around but the problem does not follow the coils. After 2 days exactly as soon as the car is turned on the engine light comes on indicating the misfire is back.
