How many kilometers should a BMW undergo a major maintenance?

[ThomasFitz]

BMW requires a major maintenance every 30,000 kilometers. Modern car maintenance includes: Primarily covering the engine system, transmission system, air conditioning system, cooling system, fuel system, power steering system, etc. A minor maintenance is recommended every 10,000 kilometers, while a major maintenance should be performed every 30,000 kilometers. If the surrounding environment is poor or the oil quality is average, the maintenance interval can be appropriately shortened. Additionally, maintenance at 4S shops generally also shortens the cycle. The purpose of car maintenance: Is to keep the car clean and in normal technical condition, eliminate hidden dangers, prevent failures, slow down the deterioration process, and extend the service life.
