All drivers must maintain their vehicles in order to maintain their reliability. However, driving a vehicle like an Audi comes with a higher level of responsibility in ongoing care. Since these cars are known for their performance, durability, and luxury, drivers have more to lose when their Audi runs into problems. Although Audi vehicles are built to last, the manufacturers give drivers a comprehensive maintenance plan that should be adhered to for optimal results. This maintenance plan includes services for spark plugs.

Since the automotive industry has recently begun to design spark plugs that are engineered tougher so that drivers don’t need to replace them as often, one might think that this applies to all Audi vehicles. However, the rate at which spark plugs deteriorate is highly dependent upon the drivers unique driving style and typical road conditions. It’s important to collaborate with an Audi specialist who can help you decide when your spark plugs need servicing. In this article, you’ll find more information about spark plug issues, including the common causes and symptoms of failure.

Common Symptoms of Failing Spark Plugs

Symptoms of failing spark plugs will range in severity depending on how far along the deterioration is. Spark plugs rarely wear out overnight, so it’s important to know what to look for in your Audi when you suspect such issues. If you notice any of the following symptoms in your Audi, it’s best to bring it to an Audi specialist as soon as possible to ensure your safety on the road and prolong your car’s reliability.

Problems Starting the Engine

When your Audi’s spark plugs begin to become worn out or fail, it may become difficult for your engine to start. Since spark plugs play a huge role in the ignition process, if they aren’t fulfilling their purpose and producing enough heat then your engine will likely have trouble turning over. However, starting issues could be due to a different part failing in the ignition process, so it’s important to perform an accurate diagnosis.

Misfiring

Engine misfiring is concerning to any driver, let alone an Audi driver who expects a higher level of performance out of their car. Engine misfiring is also a common symptom of other originating problems; however, when spark plugs begin to fail, it is not uncommon to experience engine misfiring more frequently as the problem worsens.

Decreased Acceleration Ability

One of the reasons why Audi drivers choose the brand is because of the power and endurance they offer. When you begin to notice that your Audi is losing its power upon acceleration, it could be due to failing spark plugs. Decreased acceleration ability is another concerning symptom for Audi drivers, as it takes away from the overall appeal of a high-performance vehicle.

Decreased Fuel Economy

Despite being a high-performance car, Audis offer drivers exceptional fuel efficiency. When spark plugs begin to fail, the engine cannot run optimally—particularly in the ignition and combustion processes. This can greatly affect your car’s gas mileage, as it causes more strain on the engine, leading to increased fuel consumption. If you notice a change in your fuel economy, its best to have the problem checked out by a professional.

Common Causes of Spark Plug Failure

Spark plug issues rarely occur on their own—there’s usually another sign or symptom that contributes to their failure. Two of the most common issues that occur alongside spark plug failure are oil contamination and engine overheating. These two engine conditions can cause your spark plugs to become prematurely worn out, so ongoing care is absolutely necessary to ensure all the parts are working properly.
