Where is the engine number located on a BMW 730?
2 Answers
The engine number of a BMW 730 is located on 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 found through the following 4 ways: The vehicle registration certificate prints the engine number, usually located on the second-to-last line; The motor vehicle registration certificate will state the engine number; The car purchase invoice will state the engine number; The vehicle purchase tax payment certificate will state 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 specifications 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, with each engine using only one unique engine number, and no two engines share the same number.
I clearly remember the location of the BMW 730's engine number—it's right inside the engine bay. After opening the hood, you can directly see it engraved on the upper right side of the engine block, usually on the metal surface near the windshield. When I helped a friend check it last year, he couldn't find it at first, so I advised him to let the engine cool down before proceeding to avoid burns. Wipe off the dust with a clean cloth and use a phone flashlight to illuminate the area, and the numbers will become visible. The location isn't particularly hidden, but you need to be patient because oil stains or dirt can sometimes obscure it. This number is crucial for vehicle registration or transfer of ownership—I used it to verify authenticity when I bought a used BMW 730 before. When checking the number, it's best to park and turn off the engine to avoid disturbing internal components.
