[AustinDella]

The engine number of the BMW 3 Series is located on a nameplate on the left side of the engine, on the cabin wall. Just look for the series of letters and numbers following 'ENGINE No:'. It is typically a combination of 7 to 8 digits and letters. In addition to the above method, the engine number can also be found in the following four ways: The vehicle's driving license has the engine number printed on it, usually on the second-to-last line; The motor vehicle registration certificate will specify the engine number; The purchase invoice will specify the engine number; The vehicle purchase tax payment certificate will specify the engine number. It is important to note that the engine number is not the same as the engine model. The engine model refers to the specifications and size of the engine within the manufacturer's range, and engine models can be the same. The engine number, however, refers to the production number of the engine. Each engine can only have one engine number, and every engine's number is unique.
