Signs of Coil Pack Failure

The coil pack is an essential component in Volkswagen and Audi vehicles. It’s also a part that car owners almost always overlook since most are unaware that such a component even exists. Learn to recognize the signs of coil pack failure.

What Is a Coil Pack?

A coil pack is also referred to as an engine coil. This is a bundle of spark coils that create the needed electric spark for igniting the fuel and firing the engine. Coil packs are especially common in modern German vehicles with a turbocharged direct injection engine. Coil packs eliminate the need for a distributor. The latter is prone to failure especially when exposed to water. Coil packs also have more longevity, up to 150,000 miles in some models.

Common Coil Pack Failure Symptoms

  • The engine idles roughly or stalls
  • The exhaust pipe emits smoke on an intermittent rather than steady basis
  • The gas warning light comes on despite having plenty of gasoline
  • The RPM drops significantly during acceleration
  • The engine roar sounds louder than usual
  • The check engine light blinks or randomly light on and off

Of course, many of these signs can also be symptoms of other issues. Engine stalling, for instance, is also a common sign of a worn fuel injector or pump. It might also be an indicator of a bad camshaft or be as simple as a dirty air filter. This is why you need to schedule an appointment with an auto service to pinpoint the issue. Even if not a coil pack issue, the symptoms indicate that some kind of problem exists.
