Signs and Symptoms

- Struggling to Start and Misfiring – Spark plugs play a crucial role in the starting of your engine, as they are in charge of creating the spark that ignites the fuel which in turn provides the energy needed for motion. If your spark plugs are failing or working incorrectly, one of the biggest things you’ll notice is that your car becomes tricky to start. This is because the air/fuel mixture in the engine tank is struggling to become lit. Once this issue becomes more severe, it is likely your engine will experience engine misfire regularly, which is not only inconvenient, but can cause damage to your engine systems.
- Rough Idling – Few drivers realize that the ignition process is a constant loop of steps each time new fuel enters the engine the spark plug sparks to ignite it. When this ignition is difficult, you will notice your car juddering when idling due to the engine systems working overtime to achieve combustion.
- Poor Acceleration – Many drivers chose Audi vehicles because they offer maximum power and acceleration. However, when your spark plugs are struggling, this power is noticeably reduced, particularly when accelerating.
- Poor Fuel Economy – Audi’s, as with many quality German cars, are known for the impressive miles per gallon that can be achieved, allowing you to drive farther for less. Conversely, when spark plugs are failing, the engine is not able to perform at its optimum level, leading to excessive fuel use and wastage, leaving you heading to pumps far more often and your wallet far more empty than before.
- Knock-on Effect – Spark plugs failing rarely represents an isolated event. This is typically caused as a knock-on effect from the failure of another part or system in the vehicle. Most commonly, this is from oil contamination and/or the engine overheating, so if you’ve had issues with either of these components in your Audi, it is best to also check your spark plugs condition.
