What happens if my Audi S4 spark plugs fail?

When it’s time to replace the spark plugs, don’t delay. These small (but vital!) parts provide the electric spark that your car needs in order to start, and old spark plugs can prevent your car from starting at all. Replace spark plugs on time or about every 30,000 miles or so.

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

Puddles could indicate an oil leak, coolant leak, or brake fluid leak– all of which can critically hurt your engine. Have your engine inspected as soon as you spot a pool of liquid in your usual parking spot.

What do hard starts and stops do to my S4 engine?

You can make your driving habits more engine-friendly. Hard starts and stops can increase the stress on engine parts, especially over many years. Boost your fuel economy and care for your engine by using gradual, smooth starts and stops instead.

Tune-Ups to Help Your Audi S4 Run Better

Is it time for an engine 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, especially if you want your 1994 Audi S4’s engine to last for a long time. Periodic tune-ups can bring more power back to your S4’s engine. Tune-ups help your engine start smoothly and run efficiently, so you can enjoy improved fuel economy and lower emissions. When you get routine engine tune-ups based on Audi's recommendations, you invest in your S4's long-term health and engine performance.

Audi S4 Engine Tune-Up Services

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Audi S4 engine tune-up services. The first 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. The result? Restored fuel system 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. 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 Should I Go for My Audi S4 Tune-Up?

If you’re looking for 1994 S4 engine tune-up services, head to Firestone Complete Auto Care. Not sure when you’re due for a tune-up? Use Audi’s recommended maintenance schedule as a reference point, or schedule an appointment ASAP if you notice any of these signs: shaking while the engine is idling, poor fuel economy, an illuminated check engine light on your dashboard, or a knocking sound when the engine is running.
