Hello, I'm Brandon - VW tech.

The coil will need to replaced. The coil is misfiring now this is why the check engine light is flashing.

Replaced it with a New unit, I preferred getting the OEM VW coil than aftermarket coil.

After the replacement the engine should be back to normal.

Please rate me positive, thank you!
