In addition to the many problems that can arise from a misfiring engine, bad spark plugs can cause a number of issues with your Audi Q7. Symptoms of faulty spark plugs may be subtle or quite obvious. The basic form and function of the spark plug have not altered much over the last 100 years. They sit on top of the combustion chamber and ignite the air/fuel mixture, starting the engine’s power stroke.

Modern spark plugs are more durable and require less maintenance. Many of them include iridium, don’t need to be gapped, and can survive for 100k miles with little trouble. That said, they still have a limited lifespan. The good news is that if you do need to replace them all, replacement costs are quite low.

How Often Should You Change Your Spark Plugs?

Spark plugs are somewhat hardy components that don’t have to be changed too often, but the average time is somewhere between 30,000 and 90,000 miles. The general guideline is that they should be replaced every 30,000 to 90,000 miles. While this may appear to be a simple process and may even be considered a do-it-yourself project by some people, each manufacturer has its own recommendations for when the spark plugs should be replaced.

There might be issues with components that are difficult to remove without specialized equipment. For details on when to replace the spark plugs for your vehicle, consult your owner’s handbook or speak with a professional.

Audi Q7: Bad Spark Plugs Symptoms

There are a variety of symptoms that can indicate misfiring spark plugs in your Q7. We generally recommend using an OBDII scanner to obtain trouble codes if you have a check ending light on. It may help you narrow down the field considerably. If you don’t have one, your local parts store will perform this for you for free.

It’s also worth noting that, while the symptoms of faulty spark plugs are similar to those of other problematic components in the ignition process, they may vary somewhat. This indicates that a failing coil pack, for example, would produce the same outcomes and sensations as a bad spark plug.

Check Engine Light

The check engine light is a frequent indicator of faulty spark plugs. Your car’s computer is more than capable of detecting defective spark plugs in your Q7.

There are several misfire-related trouble codes.

  • The P0300 trouble code indicates that there is a random misfire. A random misfire occurs when the ECM detects a fault but is unable to determine which one it is coming from or whether it’s occurring at random.
  • There are four other misfire-related messages. For example, P0301 through P0312 indicate a cylinder misfire. This makes determining the source of the problem somewhat easier. There are several more misfire-related messages available.

Accelerates Slower than Normal

As you request more power from your Q7, the fuel and ignition systems respond. If acceleration has dropped, it’s usually due to a problem with one of the cylinders. The fewer cylinders in your engine, the more detrimental one cylinder failing to fire will be. It’ll make the Q7’s acceleration weaker if you have any bad spark plugs installed.

Fuel Economy

The more inefficient the combustion of your engine, the more fuel will be lost. This results in reduced fuel efficiency. When you bring your car in for a tune-up because of low fuel economy, one of the first things a mechanic will check is your spark plugs (and ignition system in general).
