Ignition coils on the VW and Audi 2.0T TSI engines can have some issues. When the ignition coil fails you are likely to get a check engine light, and possibly even a flashing check engine light (You should not drive with this light FLASHING). The faults for bad ignition coils could be misfires on a single or multiple cylinders with possible fault codes being P0300, P0301(for cylinder 1), P0302(for cylinder 2) , P0303(for cylinder 3), P0304(for cylinder 4). These can be checked by swapping the ignition coils to different cylinders to determine if the misfire moves. Note: You will need access to a scan tool to determine the fault codes before and after testing (any generic scanner will work).

2.0t TSI Ignition Coil Cylinder Location

Example: Your are experiencing a fault code P0301 this indicates you have a cylinder one misfire. If the light is continuously flashing this means the misfire is constant. If your check engine light is stays lit up and you have this fault code this means your vehicle has registered a cylinder one misfire at some time (possibly multiple misfires). You should take the ignition coil in cylinder 1 and swap it with the ignition coil in cylinder 2.

If the misfire then moves from cyl 1 to cyl 2 its safe to say that the misfire is caused by a bad coil. If the misfire does not move you can then try to swap spark plugs which will also help you rule out another item. Assuming that doesn't work either you very likely have an issue with carbon build up on this intake valves or a bad fuel injector.

 

Ignition coils on VW and Audi 2.0T TSI cars do not have a maintenance interval. Many people regularly replace their coils or keep spares in case they go which can be a great way to ensure a bad ignition coil doesn't leave you stranded. When you have one go bad we generally recommend replacing them all to ensure you have good ignition coils in your car. It may not be a bad idea to replace the ignition coils every 40k or 60K (check your manual for your vehicle specs) miles when should be changing your spark plugs.
