BMW 7 Series Does Not Have an Engine Filter
3 Answers
BMW 7 Series has an engine filter. Engine Filter: The engine oil filter is located in the engine lubrication system. Its upstream is the oil pump, and its downstream is the various components of the engine that require lubrication. Oil filters can be classified by structure into replaceable, spin-on, and centrifugal types; by their arrangement in the system, they can be classified into full-flow and bypass types. Function: It filters out harmful impurities from the oil in the oil pan, supplying clean oil to moving parts such as the crankshaft, connecting rod, camshaft, turbocharger, and piston rings, providing lubrication, cooling, and cleaning effects, thereby extending the lifespan of these components.
Buddy, you might be mistaken. The BMW 7 Series definitely has an engine air filter—it's tucked near the air intake in the engine bay, filtering out dust and debris to protect the engine. Having driven many luxury cars, I know high-end models like this have ultra-precise filter designs, typically needing replacement every 10,000 to 20,000 km. If you think it 'doesn’t exist,' you might’ve missed its location or been misled by a shop—some skip reminders to save hassle. The owner’s manual even includes diagrams for checking and replacing it. This is crucial: prolonged neglect can cause carbon buildup, higher fuel consumption, or even performance issues. Next service, personally verify it—don’t let a small oversight become costly, especially with a BMW 7 Series’ repair bills.
Our family's BMW 7 Series has had its air filter replaced twice already—there's absolutely no way it doesn't have one. Just think about all the dust particles in the air while driving; they're all trapped by the filter. Without it, the engine would've given out long ago. In practice, the filter is installed under the hood, shaped like a flat box, and very easy to locate. Before long trips, I always check if it's dirty—if it's too dirty, I replace it myself. Buying a compatible filter online only costs a few hundred bucks. Maintenance is crucial for this car, especially the air filter. Poor maintenance not only makes the engine noisier but also shortens the lifespan of the cabin air filter. In short, don't believe rumors blindly. Check the manual or take a photo to consult someone knowledgeable—it can save you from wasting money on misdiagnosed repairs.
