What happens if my BMW 340i spark plugs fail?

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 BMW’s recommendations.

What should I do if I see leaks under my 340i?

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 BMW 340i 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.

Tune Into Your BMW 340i

Is it time for an engine tune-up? 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 2018 BMW 340i’s engine to last for a long time. Periodic tune-ups can bring more power back to your 340i’s engine. Tune-ups give your engine a boost in efficiency, which can lead to lower emission levels and better fuel economy. When you get routine engine tune-ups based on BMW's recommendations, you invest in your 340i's long-term health and engine performance.

Engine Tune-Up for BMW 340i

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to BMW 340i engine tune-up services. The standard Firestone Tune-Up is one service option. 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 340i. 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 340i. This can improve your fuel system’s performance (and therefore, your engine’s performance). Keep in mind that your 340i'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.
