How often should a BMW 325 be serviced?
2 Answers
BMW 3 Series requires servicing every 10,000 kilometers. Replacement schedule: Engine oil and oil filter should be replaced at every service; air filter, cabin air filter, and fuel filter are recommended to be replaced every 20,000 kilometers; spark plugs are recommended to be replaced every 50,000 kilometers; brake fluid should be replaced every two years (servicing frequency may vary depending on road conditions and regional differences). Maintenance notes: Regular cleaning of the vehicle's filters is crucial as it directly affects fuel consumption. During the operation of the internal combustion engine, dust and other impurities continuously mix with the engine oil, while oxidation from air and combustion byproducts causes the oil to gradually form sludge or deposits. This not only accelerates component wear but can also easily lead to oil passage blockages.
The maintenance interval for the BMW 3 Series is every 10,000 kilometers or 12 months, whichever comes first, as recommended by the manufacturer. The CBS onboard system will automatically adjust reminders based on your driving habits—for example, frequent city driving in traffic may require earlier inspections. Each service should include critical items such as oil changes, filter replacements, and brake system checks. Neglecting these can lead to increased carbon buildup or part wear, reducing the car's performance and lifespan. I advise owners to pay attention to dashboard alerts and address unusual noises immediately to ensure smoother engine operation and prevent on-road issues. Regular maintenance is a crucial step for safety, especially in high-performance models like the 325.
