Where is the engine number located on a BMW 5 Series?

BMW 5 Series engine number is located at the connection point between the cylinder head front end and the engine block. The BMW 5 Series engine model is N20B20. After completing the T-transformation for the inline 6-cylinder engines, BMW began introducing small-displacement turbocharged engines to gradually replace the classic N52 engine. The 4-cylinder engine numbered N20 has already been installed in models such as the X1, Z4, and the new 3 Series. Regarding the BMW 5 Series interior, it presents an overall stable and sophisticated appearance, with its fine craftsmanship and rich configurations receiving positive reviews. The seams are evenly and tightly constructed, the air conditioning performs well, the steering wheel offers good handling feel, and the display controls are convenient and user-friendly.
As a BMW 5 Series owner, when replacing parts, I need to locate the engine number, which can sometimes be quite hidden. Typically, it's located on the side of the engine block or near the engine, visible once you open the hood. From my experience, it's best to park and let the engine cool, then wipe off dust and oil stains with a cleaning cloth, and carefully search with a strong light. Different BMW models and years may vary slightly—for example, the F10 series might have it on the left front side of the engine, while the G30 series might place it near the radiator frame. Take your time, as the number is directly engraved on the metal and can be small and easy to miss. Avoid prying randomly if you can't find it, as this could damage parts. I recommend checking the owner's manual or online community videos for illustrated guides. Remember to wear gloves to avoid burns—safety first.
After years of car repair experience, I've found that the BMW 5 Series engine number is permanently stamped on the engine block, typically located on the right side or front of the cylinder block. Before checking, always disconnect the battery to prevent short circuits, then clean the area with a dry cloth. Most models feature recessed engravings that require angled lighting for proper visibility. A friendly reminder: this number is used for registration or maintenance records – don't confuse it with the VIN (Vehicle Identification Number). During servicing, you can inform technicians about its location to save time. When in doubt, take a photo for professional verification. Always ensure coolant and oil caps are properly sealed to keep the engine bay clean.
