What happens if my Audi A4 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 does a puddle underneath my Audi A4 mean?

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 A4 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.

Enhance Audi A4 Performance with a Tune-Up

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 might be time to change your ways, especially if you drive a 2004 Audi A4. Regular engine tune-ups can optimize your A4’s power on the road. 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 follow the guidelines specified by Audi for your vehicle’s tune-up schedule, you’re taking vital steps toward keeping your A4’s engine running smoother, longer.

Engine Tune-Up for Audi A4

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Audi A4 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*. The second service focuses on your A4'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 A4. This can improve your fuel system’s performance (and therefore, your engine’s performance). Consider this when choosing a tune-up service for your A4: 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. Chat with a Firestone technician before you jump into a specific service to ensure your engine tune-up money is well-spent.

Where to Get a Audi A4 Tune-Up

Schedule your next 2004 A4 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: shaking while the engine is idling, poor fuel economy, engine knocking, or an illuminated check engine light.
