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 that your vehicle is leaking coolant, oil, or brake fluid. Ignoring these leaks can lead to permanent engine damage, so address these symptoms ASAP with a tune-up service.

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

Tune Into Your Audi S4

Is it tune-up time? If you usually wait until your car has an issue to take it in for service, it might be time to change your ways, especially if you want your 2006 Audi S4’s engine to last for a long time. Regular engine tune-ups can optimize your S4’s power on the road. They're designed to help your engine start easier and run more 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

The Firestone Complete Auto Care location in your community offers several Audi S4 engine tune-up services. The standard Firestone Tune-Up is one service option. This includes the installation of new spark plugs and a visual inspection of your engine’s components, plus a lifetime warranty on parts*. A second service option replaces the air and fuel filter in your S4. The third tune-up option is a fuel system cleaning service, which is a three-step process that removes varnish, dirt, and carbon deposits on your S4's fuel injectors, throttle body, and throttle plate. The result? Restored fuel system 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. Chat with a Firestone technician before you jump into a specific service to ensure your engine tune-up money is well-spent.
