Where is the engine number stamped on the old Q7?
2 Answers
The engine number stamp on the old Q7 is located between the supercharger on top of the engine and the right-side cylinder head of the engine. Near the alternator belt and water pump pulley, there is a 45-degree inclined surface where the engine number is stamped, 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 has the engine number printed on it, 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 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, where each engine can only have one unique engine number, and no two engines share the same number.
I've worked on quite a few old Audi Q7s, and the location of the engine number stamp does depend on the specific model and year, but it's generally under the front hood. Most commonly, it's stamped on the engine block surface, near the upper right corner or the left side oil filler port. If you crouch down, you can vaguely see it. Remember to use a small flashlight since old engines might have oil stains or dust covering the area, making it hard to spot. It's best to use a mirror to help check the angle, and avoid directly touching hot engine parts to prevent burns. This number is crucial for vehicle transfers, insurance, or anti-theft purposes. If you can't find it yourself, the quickest way is to ask a professional auto repair shop for help—they have the tools and experience. The old Q7 often comes with V6 or V8 engines, and the location is the same; just be patient, and you'll get it done.
