Where is the engine number of the BMW 730 located?
3 Answers
The engine number of the BMW 730 is located on the engine block. It usually consists of 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 4 ways: The vehicle's driving license contains the engine number, usually located on the second last line; The motor vehicle registration certificate will state the engine number; The purchase invoice will state the engine number; The vehicle purchase tax payment certificate will state 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, and engine models can be the same. The engine number, however, refers to the production number of the engine, with each engine having a unique number that cannot be duplicated.
Every time I work on my car, I have to be extra careful when looking for the engine number, especially on luxury models like the BMW 730. The engine number is usually stamped on the engine block, so you'll need to open the hood and search for small engravings or stickers. Specifically, for the 730 series, the number is mostly stamped on the front or side of the engine, and you might need to remove some plastic covers to see it clearly. I recommend doing this with the engine off, using a phone flashlight for better visibility to avoid glare in strong light. If it's covered in grease, spraying some cleaner and wiping it off will make it easier to identify. Why do you need this? For example, when buying insurance or transferring ownership, you'll need it to match records, otherwise the paperwork can be troublesome. A tip from experience: check the appendix of the owner's manual—it usually has a diagram of the location. If you can't find it, take a photo of the VIN code and look it up online, but don't force open any parts to avoid injuring your hands.
With my extensive car repair experience, the engine number of a BMW 730 is typically stamped directly on the engine block. The location is usually in the stamped area on the top or side of the engine under the hood. After opening the hood, note that the position varies by year—the 1990s E32 model has it near the front cam cover, while the newer F01 series is located closer to the rear of the radiator. I always wear gloves to avoid oil stains and use a small brush to clear dust for easier identification. The number is crucial for tracking engine replacement history. A related issue: if the digits are faded, registration can be troublesome and may lead to insurance disputes. A simple detection method: keep a magnifying glass handy or use your phone's macro mode to take a photo for inspection. Safety tip: ensure the engine is cold before checking, and avoid touching hot piping systems. If you still can't locate it, rely on professional scanning equipment or consult the manual—it saves time and effort.
