Where is the engine number of Audi A4L?
2 Answers
The engine number of the A4L is located on the inclined surface of the cylinder block at the rear end of the engine where it connects to the transmission. 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, to a batch of identical products. It represents information such as the manufacturer, specifications, performance, features, technology, application, and production batch of the engine, including details like fuel type, number of cylinders, displacement, and static braking power.

It represents information such as the manufacturer, specifications, performance, features, technology, application, and production batch of the engine, including details like fuel type, number of cylinders, displacement, and static braking power. Engines installed in passenger cars or multi-purpose passenger vehicles are required to clearly indicate the professional manufacturer, model, and production number of the engine. 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 product line, and engine models can be identical. The engine number, however, refers to the production number of the engine. Each engine can only have one engine number, and the number is unique to each engine. Composition of the vehicle engine number: Front section: Includes product series code, generation symbol, and regional or corporate code. Manufacturers can choose the appropriate letters as needed, but they must be approved and filed by the industry standard's standardization unit. Middle section: Consists of symbols for the number of cylinders, cylinder arrangement, stroke, and cylinder diameter. Rear section: Comprises symbols for structural features and application characteristics. Tail section: Distinguishing symbol. When differentiation is needed within the same product series due to improvements or other reasons, the manufacturer selects an appropriate symbol. The rear and tail sections can be separated by a hyphen (-).
Last time I helped a friend locate the engine number of an Audi A4L, it took some effort. After opening the hood, it's usually engraved on the upper part of the engine block, specifically on the right side or front of the cylinder block, with a small label or directly stamped numbers. It's easier to see in good lighting, and it's recommended to operate after the car has cooled down to avoid burns. I found wiping off the dust makes it clearer, typically used for vehicle registration or maintenance records. Don't confuse it with the VIN number under the windshield. If you can't find it, try taking a photo and zooming in to check. It's a practical tip, simple but requires attention to detail, as it affects subsequent procedures.
