Coil pack failures and engine misfire have been a chronic problem for many VW/Audi owners. The symptoms are predictable: the engine misfires and the check engine light illuminates steadily, or blinks. Ignore the problem and you'll ruin your expensive catalytic converter and fail your local emissions test.
If your engine is experiencing these issues, then it's time for an ECS ignition service kit. This kit contains a complete set of updated ignition coils, spark plugs, and dielectric spark plug boot protective silicone.
