Will it hurt my Audi S4 to drive with old spark plugs?

Replace spark plugs on time or about every 30,000 miles or so. Without the spark of electricity created by spark plugs, your engine doesn’t have the combustion it needs to start — which could leave you stranded on the road. Always replace your spark plugs on time based on Audi’s recommendations.

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 it tune-up time? If you usually wait until your car has an issue to take it in for service, it could be time for a new way of doing things, especially if you want your 2018 Audi S4’s engine to last for a long time. Routine engine tune-ups can bring power back to your S4. Tune-ups help your engine start smoothly and run efficiently, which can lead to lower emission levels and better fuel economy. When you take your car for regular engine tune-ups as recommended by Audi, you invest in your S4's long-term health and engine performance.

Engine Tune-Up for Audi S4

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Audi S4 engine tune-up services. One option is the standard Firestone Tune-Up. The standard Firestone Tune-Up includes new spark plugs (and installation!), a thorough inspection of engine components, and a lifetime parts warranty*. Another service option pays special attention to the filters in your S4. Specifically, we replace the fuel filter and air 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. Consider this when choosing a tune-up service for your S4: your vehicle’s maintenance record and mileage can determine which service is best. A one-size-fits-all engine tune-up procedure doesn’t necessarily exist. Talk to a technician about your driving style, mileage, and service history to learn more about your vehicle's specific needs.

Where Should I Go for My Audi S4 Tune-Up?

Schedule your next 2018 S4 engine tune-up service at Firestone Complete Auto Care. Follow Audi's recommended maintenance schedule or book an appointment as soon as you notice one of the following: stalling or shaky idling when you’re stopped, diminished fuel economy, an illuminated check engine light on your dashboard, or a knocking sound when the engine is running.
