Engine oil should be replaced every 5,000–10,000 kilometers (or as recommended by the vehicle’s manual) to ensure smooth engine operation and prevent wear.

The engine air filter should be checked and replaced periodically (typically every 10,000 to 20,000 kilometers) to ensure optimal engine performance and fuel efficiency. The cabin air filter, which ensures clean air inside the car, should also be replaced periodically

Tire pressure should be checked regularly, and tires should be rotated every 10,000 kilometers to ensure even wear. Balancing and alignment are also important to avoid uneven tire wear and to improve driving comfort and fuel efficiency.

Brake pads and rotors should be inspected every 20,000 kilometers or more frequently if you notice any squeaking, reduced braking performance, or vibrations while braking. Replacing brake pads when they are worn is critical for safety.

Car batteries generally last 3–5 years. Regular checks can prevent unexpected breakdowns, and any signs of corrosion on battery terminals should be cleaned to ensure good connection.  

Regularly check and top off essential fluids such as coolant, brake fluid, power steering fluid, transmission fluid, and windshield washer fluid

Over time, suspension components like shocks, struts, and bushings can wear out, leading to poor handling and a rough ride. If you notice vibrations, unusual noises, or steering difficulties, these parts may need attention.

If the radiator or cooling system is not functioning properly, it can lead to engine overheating. Regular checks of coolant levels, hoses, and radiator can prevent serious damage.

Exhaust components, including the catalytic converter, muffler, and exhaust pipes, can corrode over time. If your car makes unusual noises or shows signs of poor engine performance, an exhaust system inspection is advised

Headlights, brake lights, and electrical systems like fuses and wiring can sometimes malfunction. Quick repairs of faulty lights and electrical components are important for safety and to avoid more serious electrical issues.

Transmission problems such as slipping gears, rough shifting, or a delayed response require immediate attention. Similarly, engine misfires, poor fuel efficiency, or unusual sounds may indicate internal engine problems.

The battery charging system is responsible for keeping the vehicle's electrical systems powered and recharging the battery while the engine is running. This system includes the alternator (dynamo), voltage regulator, and the battery itself.

While the starter motor generally requires little routine maintenance, it’s a good idea to inspect it during regular service intervals. Ensure there are no loose connections or visible damage to the wiring.

The fuel system in your BMW vehicle is responsible for delivering the correct amount of fuel to the engine to ensure smooth operation and optimal fuel efficiency. The system includes components like the fuel pump, fuel injectors, fuel filter, fuel tank, and fuel pressure regulator.
