When should BMW 840i xDrive spark plugs be replaced?

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 do I do if I see a pool of liquid under my BMW 840i xDrive?

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.

What do hard starts and stops do to my 840i xDrive 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.

Regular engine tune-ups can optimize your 840i xDrive’s power on the road. They're designed to help your engine start easier and run more efficiently, 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 invest in your 840i xDrive's long-term health and engine performance.

Routine Engine Tune-Up Service for Your BMW 840i xDrive

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to BMW 840i xDrive engine tune-up services. One option is the standard Firestone Tune-Up. It includes a complete visual inspection of engine components, installation of new spark plugs, and a lifetime warranty on parts*. A second service option replaces the air and fuel filter in your 840i xDrive. 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 840i xDrive’s fuel injectors, throttle body, and throttle plate. This can improve your fuel system’s performance (and therefore, your engine’s performance). Here’s something to remember when choosing services: the mileage and service history of your 840i xDrive can determine what kind of service it needs. This means that a tune-up service that’s a great fit for another car may not be optimal for yours. Ask one of our technicians what your vehicle needs, based on your driving habits and your car’s current condition.
