How often should the BMW 7 Series be serviced?
3 Answers
The BMW 7 Series should be serviced every 10,000 kilometers or once a year. Regular maintenance can reduce wear and tear on components and extend the vehicle's lifespan. Failure to service the car on time may impair its performance. The BMW 740Li is a high-end luxury sedan belonging to the BMW 7 Series. Its dimensions are 5179mm in length, 1902mm in width, and 1484mm in height, with a wheelbase of 3128mm. In terms of exterior design, the BMW 7 Series continues the mature and stable styling of its predecessor. The front fascia features enlarged kidney-shaped grilles, and the headlights connected to the grille adopt an upward-slanting design. The interior showcases a wraparound dashboard design, with digital instrument clusters and a layered center console that further highlight the car's modern and stylish appeal.
Having driven a BMW 7 Series for five years, I've gained considerable expertise in maintenance. The official recommendation is servicing every 10,000 kilometers or once a year, whichever comes first. However, since I frequently drive on highways, I opt for an early check-up at 8,000 kilometers. Engine oil and oil filters must be replaced every time, while air filters are best changed every 20,000 kilometers. In my car enthusiast group, someone delayed maintenance until 15,000 kilometers, resulting in increased engine noise and an extra 2,000 yuan spent on carbon deposit cleaning. Brake fluid must be replaced every two years; otherwise, braking distance becomes dangerously long in rainy conditions. Before summer, I also replace the cabin air filter to ensure odor-free air conditioning. Oh, and don’t forget to regularly check tire wear—tire rotation is crucial for rear-wheel-drive cars. Keeping these intervals in mind can save you a lot on repair costs.
I usually receive cars at the 4S dealership, and the BMW 7 Series maintenance cycle is quite transparent. The vehicle's computer system provides maintenance reminders based on actual driving habits, typically indicating 10,000 kilometers or 12 months. However, there are three situations to pay attention to in practice: if road conditions are poor, check the remaining engine oil at 8,000 kilometers; for those who frequently drive short distances, it's recommended to inspect the battery every ten months; northern car owners should test the antifreeze concentration before winter. The core items are replacing the engine oil and oil filter, while others like spark plugs can be delayed until 60,000 kilometers. Brake fluid must be replaced every two years—we've seen too many cases where owners forget to change it, resulting in soft brakes. During major maintenance, remember to perform a wheel alignment simultaneously, as the 7 Series has a heavy body and tires wear unevenly faster.
