Where is the engine number located on the Audi A4L?

The engine number of the A4L is located on the inclined surface of the engine block at the rear end 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. It is used to represent information such as the manufacturer, specifications, performance, characteristics, technology, purpose, and production batch of the engine, including fuel type, number of cylinders, displacement, and static braking power.

Engines installed in passenger cars or multipurpose passenger vehicles are required to clearly indicate the professional engine manufacturer, model, and production 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 product line, and multiple engines can share the same model. The engine number, however, refers to the production number of the engine. Each engine can only have one unique engine number, and no two engines share the same number. Composition of the vehicle engine number: Prefix: Includes product series code, generation symbol, and regional or corporate code. Manufacturers may choose appropriate letters as needed, but these must be approved and filed by the industry standard regulatory body. Middle section: Consists of symbols for the number of cylinders, cylinder arrangement, stroke, and cylinder diameter. Suffix: Composed of symbols for structural features and intended use. Tail: Distinguishing symbol. If differentiation is needed within the same series due to improvements or other reasons, the manufacturer may select an appropriate symbol. The suffix and tail may be separated by a hyphen.
I've been driving an Audi A4L for years, and every time I need to check the engine number, I have to pop the hood to look. It's usually engraved on the side of the engine block, near the right side close to the windshield. Upon closer inspection, you'll see a combination of numbers and letters. Once when selling the car for transfer, it took me half an hour to find it because dust had covered it—later, wiping it clean with a damp cloth did the trick. I recommend doing this when the engine is cold for safety, and avoid touching hot components with your fingers. If you can't find it, try looking up from underneath the car—sometimes it's positioned a bit lower, but for the A4L, it's mainly on the engine block, so don't confuse it with the VIN label. Regular maintenance checks can prevent rust from affecting readability.
I've helped friends check the engine number of the Audi A4L several times, and the location is quite consistent. It's generally located in the engine compartment, specifically on the top right of the cylinder block, often partially obscured by pipes and the air filter. Squatting down will give you a clear view. Remember to use a flashlight in low light conditions, as it's easy to miss otherwise. Last time, the mechanic advised keeping the area clean—excessive oil buildup can make it hard to identify, which is crucial for maintenance records. If the vehicle is older, the position might vary slightly, but the main location remains the same. Don’t doubt yourself; with patience, you’ll always find it.
