What items are required for BMW's second maintenance?

[DiJeremiah]

BMW's second maintenance, which is the second service, is performed at 10,000 kilometers. The basic items include changing the engine oil and oil filter. Some models may require replacing the air and cabin air filters. The second maintenance also involves inspection and servicing of dozens of items across multiple systems, including the engine, transmission, air conditioning system, steering system, braking system, suspension, body, and tires. The inspection and maintenance items are divided into the following four parts: 1. Replace the engine oil, oil filter, and air filter. Check the tension and speed of the engine belt, as well as the condition of various fluids. 2. Check the tire pressure and look for any bulges, damage, or uneven wear. 3. Inspect the chassis, brake pads, brake discs, ball joints, CV joints, and connecting rods for any scratches or damage. 4. Finally, check the lights and all switches in the vehicle.

I've been driving a BMW for five or six years, and the second maintenance is basically done according to the service manual. Engine oil and oil filter must be replaced with new ones. BMW engines are delicate, so using original full synthetic oil is the most reliable. The air filter gets very dirty after more than 10,000 kilometers, and if not replaced, the engine will struggle to breathe. Brake system inspection is particularly important—checking if the brake pads have enough thickness, whether the tire wear is uneven, and adjusting the tire pressure to the standard value. During my last second maintenance, I also asked the technician to specifically check the coolant's freezing point and the brake fluid's water content, especially since winter requires antifreeze protection. Tightening chassis screws and inspecting suspension bushings are also routine items, and if you've driven on rough roads, a more thorough check is necessary. Finally, don’t forget to have them connect to the computer to check for any hidden fault codes. The whole process takes about two hours, and after maintenance, the throttle response becomes noticeably smoother.

In our car enthusiast circle, we all know that BMW's second maintenance directly impacts performance. Last year, I focused on powertrain maintenance during my second service: replaced with high-performance full synthetic oil and the original oil filter to keep the N20 engine in top condition. Upgraded the intake system with a new air filter to improve air intake efficiency. Specifically measured the brake fluid's water content, and immediately replaced it when it exceeded 3%. Had the technician adjust the tire pressure during wheel balancing, with 2.3 in the front and 2.5 in the rear being ideal. The most surprising find was a fine crack in the coolant reservoir, which was replaced under warranty for free. I recommend bringing your own cabin air filter to save on labor costs, but the underbody guard bolts must be re-tightened by the dealership with a torque wrench. After maintenance, fuel consumption dropped by 0.8 liters, and cornering support became more solid.

A 320i owner who just completed the second maintenance shares experience. Must-do items include engine oil and filter replacement, approximately 6.5 liters of 0W-30 oil. It's recommended to replace the cabin air filter (aftermarket ones cost around 200 yuan) and engine air filter. All free inspection items should be done: brake pad thickness measurement (replace if below 5mm), tire tread depth check, and full vehicle lighting test. Coolant only needs topping up, not a complete replacement. I declined the engine cleaning package but spent 99 yuan on sunroof rail lubrication. Remember to check if the windshield washer reservoir is clogged with leaves. The whole process took 2 hours, with basic maintenance and labor costs totaling just over 2,000 yuan.
