Audi's engine number can be seen by opening the engine hood and removing the plastic engine cover. Here are the specific details: 1. Engine model: The engine model is an identification code assigned by the engine manufacturer in accordance with relevant regulations, industry practices, or company standards to distinguish a batch of identical products. It represents information such as the manufacturer, specifications, performance, features, technology, purpose, and production batch of the engine, including fuel type, number of cylinders, displacement, and static braking power. 2. Digits: The Audi engine number consists of 6 digits.

When driving my Audi, I've also pondered about the numbering system. Actually, Audi engines don't have a specific concept called 'motor number' at the beginning of their serial codes. You might be referring to the first few digits of the VIN (Vehicle Identification Number). The VIN is a 17-character alphanumeric combination, typically located on a label in the lower left corner of the windshield or on the door frame. The first three characters like 'WAU' represent the Audi brand, while characters 4 through 8 describe the vehicle model, engine type, etc., but this isn't directly called a 'motor number'. On my Audi A4, the engine number is independently located on the engine block as a standalone code without any prefix numbers. For accurate information, it's best to check the vehicle registration document or manual, which clearly specifies the correspondence between the VIN and engine number, thus avoiding confusion and ensuring proper vehicle maintenance.

When discussing Audi's numbering system, the VIN code is crucial. It consists of 17 characters, with the first three identifying the manufacturer—for example, WAU is exclusive to Audi. The fourth digit may indicate the vehicle series, but the engine number itself is a separate serial number stamped on the engine block, without the prefix 'motor number.' I recommend first locating the VIN plate under the windshield, noting down the full code, and then comparing it with the engine number in the engine bay. Audi's official website offers a VIN decoding service—simply enter the complete number to retrieve detailed information about the engine type. It's very convenient and reliable, allowing you to resolve most questions on your own.

When my son first bought a car, he was also confused by a similar issue. There is no so-called 'front motor number' on Audi vehicles—it was likely a misunderstanding of the beginning part of the VIN. A standard 17-digit VIN, such as one starting with WAU, is the Audi identification code. The small plate found near the engine is an independent engine number, separate from the VIN with no prefix relationship. When actually driving, it's best to carry the vehicle manual or have a photo of the VIN on your phone in case of malfunctions. Those numbers help technicians diagnose issues quickly, saving time and ensuring safety.
