What happens if my Audi S4 spark plugs fail?

Replace spark plugs on time or about every 30,000 miles or so. Spark plugs are small but mighty. The spark of electricity that the plug emits across a small gap creates the ignition for the combustion needed to start your car. Without that spark, your car won't start.

What do I do if I see a pool of liquid under my Audi S4?

Don't ignore puddles of fluid under your Audi S4. It could signal a coolant leak, brake fluid leak, or an oil leak. Let any one of these leaks linger and it could cause engine damage.

Are hard starts and stops bad for my Audi S4 engine?

Hard stops and starts can lead to premature wear on your engine’s components. Lighten up that lead foot and opt for steady, fluid starts and stops instead. Your engine (and your passengers!) will thank you.

Enhance Audi S4 Performance with a Tune-Up

Is your engine overdue for a tune-up? If you're the type of driver who waits for something to go wrong with your vehicle, it could be time for a new way of doing things, particularly if you want to keep your 2021 Audi S4 in tip-top shape. Routine engine tune-ups can bring power back to your S4. Tune-ups give your engine a boost in efficiency, which can mean better fuel economy (a win for you) and lower emissions (a win for the environment). When you get routine engine tune-ups based on Audi's recommendations, you can rest assured you’re investing in your S4’s long-term engine performance.

Engine Tune-Up for Audi S4

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 2021 Audi S4. One option is the standard Firestone Tune-Up. This includes the installation of new spark plugs and a visual inspection of your engine’s components, plus a lifetime warranty on parts*. The second service focuses on your S4's filters, specifically replacing the air filter and fuel filter. Yet another service is a fuel system cleaning process, which involves removing varnish, dirt, and carbon deposits that have built up inside the fuel injectors, throttle body, and throttle plate in your S4. This goes a long way in boosting your fuel system’s overall performance. Keep in mind that your S4's mileage and maintenance history can uniquely impact its tune-up needs. This means that a tune-up service that’s a great fit for another car may not be optimal for yours. Talk to a technician about your driving style, mileage, and service history to learn more about your vehicle's specific needs.

Where to Get a Audi S4 Tune-Up

Schedule your next 2021 S4 engine tune-up service at Firestone Complete Auto Care. Consult your vehicle’s recommended service schedule from Audi, or make a service appointment if you notice any of these symptoms from your engine: shaking while the engine is idling, poor fuel economy, knocking noises in the engine, or a lit up check engine light on your dashboard.
