Where is the engine number located on a Mercedes-Benz R350?
2 Answers
The engine number of the Mercedes-Benz R350 is located at the rear right side of the engine, specifically on the upper part where the engine connects to the transmission. It typically consists of a 7 to 8-digit alphanumeric combination. In addition to the above method, the engine number can also be found through the following 4 ways: The vehicle's driving license displays the engine number, usually on the second last line; The motor vehicle registration certificate records the engine number; The car purchase invoice states the engine number; The vehicle purchase tax payment certificate indicates the engine number. Please 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 identical. The engine number, however, refers to the production serial number of the engine. Each engine can only have one unique engine number, and no two engines share the same number.
I've driven a Mercedes-Benz R350 for several years and have experience locating the engine number. Generally, it's on the engine block under the hood, specifically near the right or left cylinder wall, engraved with a serial number. When I first bought the car, it took some time to find it for registration: you need to open the hood, ensure the engine is off for safety, and gently wipe the oily area with a cloth or cleaner to reveal the metal plate with the number. It's clearer under strong light or a phone flashlight—just avoid touching the engine when it's hot to prevent burns. Here's a tip: first locate the area near the air filter, where the number is often stamped. Take a photo for future reference during maintenance or resale. Though the spot isn't obvious, it's easy to find with a few steps. If you run into trouble, check the owner's manual or use the Mercedes official app for a location diagram—it helps.
