Where is the engine number located on the Audi Q7?

The engine number of the Q7 is located between the supercharger on top of the engine and the right cylinder head, near the generator belt and water pump pulley. There is a 45-degree inclined surface where the engine number is stamped. It typically consists of a combination of 7 to 8 digits and letters. 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 located on the second-to-last line; The motor vehicle registration certificate records the engine number; The car purchase invoice includes the engine number; The vehicle purchase tax payment certificate states 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's lineup, and engine models can be the same. 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.
When repairing cars, I often encounter customers asking where the engine number of the Audi Q7 is located. It is mainly found on the engine block itself in the engine compartment. After opening the hood and facing the engine, the number is usually engraved on a metal plate on the side or top of the engine block, such as near the intake manifold. For some models, like the diesel version, it might be located at the lower right corner of the cylinder head. Dirt can obscure it, so cleaning the area and using a strong flashlight to see the raised numbers makes it easier. This number is crucial—it’s used by repair shops to order parts and during vehicle transfers, so don’t randomly search for it; refer to the manual for specific diagrams to avoid mistakes. When checking it yourself, ensure the engine is cool before touching it—safety first to prevent burns. Keeping it clean during regular maintenance makes it easier to identify. The location varies slightly by year; pre-2010 models have it at the front of the engine, while newer models place it near the exhaust system. If you can’t find it, consult a professional.
My own Audi Q7 had an issue before, and I researched the engine number location when preparing to sell the car. After parking the car and opening the hood, look for small raised metal characters on the right side of the engine block, usually near the intake pipe. That day, I spent some time wiping off grease stains with a cloth before finally seeing the number sequence clearly. Make sure the lighting is bright—otherwise, even a mirror won’t help. Don’t underestimate this detail; you’ll need to provide it when registering at the DMV or for repairs, or else mismatched parts could cause major trouble. By the way, checking after a car wash makes it easier since less dust makes it more visible. Different engines like the 3.0TFSI have similar locations but slight variations—the manual will specify the exact spot. Safety warning: Don’t reach in and touch anything while the engine is hot.
