[DallasMarie]

BMW series engine numbers are located on the engine block, at the connection point between the front of the cylinder head and the engine block. It typically consists of a combination of 7 to 8 digits and letters. In addition to the above method, the engine number can also be checked through the following 4 ways: The vehicle's driving license contains the engine number, usually located on the second last line; The motor vehicle registration certificate will specify the engine number; The car purchase invoice will indicate the engine number; The vehicle purchase tax payment certificate will specify the engine number. It should be noted that the engine number is not the same as the engine model. The engine model refers to the specification and size of the engine within the manufacturer, and engine models can be the same. The engine number refers to the production number of the engine, where each engine can only have one unique engine number, and each engine's number is different.
