BMW 320li 100,000 kilometers maintenance items are to replace the transmission oil tank. Transmission oil tank If the transmission oil is not regularly replaced, for the vehicle, during driving, the gears inside the transmission will operate at high speed and generate heat through friction. At this time, transmission oil is needed to lubricate and reduce the temperature, ensuring the normal operation of the vehicle, while also reducing oil loss under harsh operating conditions. Transmission maintenance: Regularly check whether the automatic transmission oil level is normal. Engine oil should be checked when the car is cold, while automatic transmission oil needs to be preheated to about 50°C. During normal use, the working temperature of automatic transmission oil is about 120°C, so high-quality automatic transmission oil should be selected.
My BMW 320Li has been running for over eight years, and the 100,000-kilometer mark was a major maintenance milestone with a comprehensive inspection list. Key items included changing the engine oil, oil filter, air filter, and fuel filter—routine replacements to ensure proper engine lubrication. The spark plugs were also replaced, as worn ones can cause sluggish acceleration and higher fuel consumption. For the braking system, the brake pads and discs were inspected and replaced if severely worn—safety comes first. The coolant was completely refreshed to prevent engine overheating damage. Transmission fluid replacement was recommended, especially for automatic transmissions to avoid jerky shifts. Suspension components like ball joints and shock absorbers were checked for tightness, and while BMW's timing chains are durable, the belts still needed inspection for abnormalities. Additionally, I requested checks on battery voltage, tire wear, and lighting systems. The total cost was around 4,000 RMB, but the car runs much smoother now. Booking an appointment with the 4S store in advance saved time and hassle.
