Where is the engine number located on the Audi A6L?

The engine number of the A6L is located on the lower left side of the engine, near the flywheel position. The engine model is an identification code assigned by the engine manufacturer in accordance with relevant regulations, corporate or industry practices, and the attributes of the engine. It is used to represent information such as the manufacturer, specifications, performance, features, processes, intended use, and production batch of the engine, including fuel type, number of cylinders, displacement, and static braking power. 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 multiple engines can share the same model. On the other hand, the engine number is the production serial number of the engine, and each engine has a unique number that cannot be duplicated. Composition of the vehicle engine number: Prefix: Includes the product series code, generation symbol, and regional or corporate code. Manufacturers can choose appropriate letters as needed, but these must be approved and recorded by the industry-standard regulatory body. Middle section: Consists of symbols for the number of cylinders, cylinder arrangement, stroke, and bore diameter. Suffix: Comprises symbols for structural features and intended use. Tail: Distinguishing symbol. When differentiation is required due to improvements or other reasons within the same product series, the manufacturer selects an appropriate symbol. The suffix and tail can be separated by a hyphen (-).
I remember when I was transferring the car ownership, I specifically checked the manual and found that the engine number of the Audi A6L is actually located on the engine block itself, near the metal plate on the side of the cylinder head. Just pop open the front hood, and you’ll spot it engraved there—super convenient for verifying vehicle details. If the lighting is poor, a flashlight can help. During routine maintenance, make sure oil stains don’t cover it, or you’ll have a tougher cleanup job. After learning this key detail, I always advise friends to personally check before registration or repairs to avoid last-minute panic. Though the location is fixed, slight adjustments may exist across model years, so it’s safest to feel around (with the engine off) before starting the car.
Having driven for over a decade, I'm quite familiar with the engine number location of the Audi A6L: it's usually found on a conspicuous spot of the engine block in the engine bay, like on a small metal plate on the side or bottom of the cylinder block. When looking for it, I recommend turning off the engine and letting it cool for a while to avoid burning your hands and to get a clearer view. Also, don't overlook that the vehicle registration book also prints the number—double-checking ensures accuracy. If it gets dirty, just wipe it with a towel; it's pretty hassle-free. From my experience, maintaining this detail well brings great benefits for later insurance processing and annual inspections, saving a lot of trouble.
