BMW 325li's first maintenance mainly focuses on inspections. Inspection items: Replace engine oil, oil filter, clean air filter; check whether the generator belt and wiper blades are damaged; check whether the levels of various fluids are normal; check whether the tire pressure is normal and whether there is uneven wear, bulging, or damage on the tires; inspect the car chassis: including brake pads, brake discs, connecting rods, ball joints, and CV joints for scratches, etc.; check all switches and lights to ensure they are working properly. First maintenance mileage: The first maintenance is due at 10,000 kilometers. After the first maintenance, maintenance is required every 10,000 kilometers. Each routine maintenance requires the replacement of engine oil and oil filter. The vehicle's three-guarantee validity period is two years or 50,000 kilometers, and the warranty period is three years or 100,000 kilometers, whichever comes first. A full vehicle inspection is required every 60,000 kilometers.

I just had the first maintenance service for my BMW 325li, and it was quite hassle-free. The core items included changing the engine oil and oil filter to ensure proper lubrication for the new engine; they also checked the brake system for wear and measured tire pressure to ensure it meets standards. All lights were tested, especially for nighttime driving safety; various fluids like coolant and brake fluid levels were inspected to prevent leaks and potential hazards. I recommend bringing the vehicle manual—4S shops usually perform these services for free, and some even offer complimentary car washing. Remember to do it around 10,000 km; don’t wait until strange noises appear before rushing in. From personal experience, booking an appointment and avoiding peak hours can save a lot of time.

As experienced drivers who have driven many cars, I have extensive knowledge about the first maintenance of the 325Li. The primary tasks include changing the engine oil and filter to prevent carbon buildup from damaging the engine; checking the brake pad thickness, tire wear, and wheel balance; as well as inspecting the chassis for loose screws and overall body stability. Regular maintenance is crucial, and completing the first maintenance thoroughly can extend the vehicle's lifespan and reduce future repair costs. I usually perform a quick check on the car's condition myself, such as changing the oil if it appears black. It's advisable to keep a record of maintenance dates and maintain a logbook, reporting any issues promptly. Don’t overlook free service items, and always ask the service advisor for details.

I've been following automotive technology for a long time. The key points of the 325Li's first maintenance focus on performance upkeep: replacing synthetic oil with specific viscosity matching engine requirements, upgrading to high-efficiency filters for optimized filtration; ECU system diagnostics to clear potential fault codes; tire pressure adjustment and brake response testing are essential. This ensures smooth vehicle operation and improves fuel efficiency. I usually monitor oil consumption, and the first maintenance is an opportunity to lay a solid foundation. It's recommended to choose an authorized service center and use BMW-certified consumables to avoid affecting the warranty.
