When should BMW 540i spark plugs be replaced?

Replace spark plugs on time or about every 30,000 miles or so. Spark plugs are small but mighty. The spark of electricity that the plug emits across a small gap creates the ignition for the combustion needed to start your car. Without that spark, your car won't start.

What should I do if I see leaks under my 540i?

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.

Are some driving habits better for my BMW 540i engine than others?

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 BMW 540i 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 1994 BMW 540i’s engine to last for a long time. Routine engine tune-ups can bring power back to your 540i. 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 take your car for regular engine tune-ups as recommended by BMW, you’re taking vital steps toward keeping your 540i’s engine running smoother, longer.

Routine Engine Tune-Up Service for Your BMW 540i

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to BMW 540i 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*. Another service option pays special attention to the filters in your 540i. Specifically, we replace the fuel filter and air filter. Our third service is a thorough cleaning of the fuel system. During this type of tune-up, we use a three-step process to get rid of harmful varnish, dirt, and carbon deposit buildup in your 540i’s fuel injectors, throttle body, and throttle plate. This can improve your fuel system’s performance (and therefore, your engine’s performance). Consider this when choosing a tune-up service for your 540i: your vehicle’s maintenance record and mileage can determine which service is best. If you’re not sure what services are the best fit for your car, let us help! Ask one of our technicians what your vehicle needs, based on your driving habits and your car’s current condition.
