Where is the BMW i8 engine number located?

The BMW i8 engine number is located on the engine block, typically consisting 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 will display the engine number, usually located on the second-to-last line; The motor vehicle registration certificate will record the engine number; The car purchase invoice will state the engine number; The vehicle purchase tax payment certificate will indicate the engine number. It's 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 lineup, and engine models can be the same. The engine number, however, refers to the production number of the engine, with each engine assigned a unique number that cannot be duplicated.

The engine number of the BMW i8 is usually located in the rear engine compartment, visible after opening the rear hatch. It is typically engraved on a metal plate on the left side of the engine, near the radiator fan below—requiring a close look. It's advisable to turn off the engine and wear gloves and safety goggles to avoid burns or getting dirty. When I first bought my i8, it took some effort to locate it, and I had to refer to the owner's manual illustrations for confirmation, as the hybrid system's compact layout can be confusing. This number is crucial for vehicle transfers or repairs. If it's worn and illegible, don't panic—a BMW dealership can retrieve it using the VIN. During routine maintenance, check its visibility to avoid future hassles.

When assisting with BMW i8 repairs at the auto shop, we often locate the engine number on the engine casing inside the rear hood, specifically on a small label at the front of the cylinder block. You'll need to unlock the rear cover, secure the support bracket, then use a flashlight to inspect the engraved digits on the label. The concealed placement reflects the i8's unique rear-mounted hybrid engine design with its dense cooling system. I always advise friends to regularly clean that area to prevent grime from obscuring the ID plate. If the number proves elusive, photographing the VIN (Vehicle Identification Number) and cross-referencing it in the system is a more reliable alternative. The engine number links to service records – verifying it upfront saves considerable troubleshooting later.

My experience in locating the i8 engine number by myself is to go straight to the rear of the car and open the rear engine cover. The small plate with the engine number is engraved on the lower right corner of a metal block inside. Bringing tools like a flashlight makes it easier—just take a glance and note down the numbers. Remember to park safely and turn off the engine to avoid accidentally touching any wires. This simple method is suitable for regular car owners and doesn’t require a technician. The manual and online videos also provide reference illustrations. The location is important for providing accurate information during vehicle registration, so it’s recommended to take a photo and save it in your records for future reference.
