Where is the engine model number on an Audi TT?
4 Answers
Audi TT's engine model number is located on the side wall of the cylinder block, where there is a machined platform approximately 5-6 centimeters long and one centimeter wide, bearing the engine number. Alternatively, some models display this information on the vehicle's identification plate. The engine model number is assigned by the manufacturer in accordance with relevant regulations or industry practices to indicate details such as the manufacturer, specifications, performance, features, technology, intended use, and production batch of the engine. The prefix of the engine number consists of product series and generation symbols, represented by letters chosen by the manufacturer and approved by relevant authorities. The middle part includes symbols for the number of cylinders, stroke type, cylinder arrangement, and cylinder diameter. The suffix denotes structural and usage characteristics, represented by letters, while the tail end serves as a distinguishing symbol.
The simplest way to find out the engine model of an Audi TT is to open the engine hood and look directly at the engine block. Typically, the engine model is engraved on the side of the metal cylinder block or on a top-mounted nameplate. Use a flashlight to search for it—common locations are near the intake manifold or close to the firewall. The alphanumeric combinations printed on these nameplates, such as CDL or CJXC, are the model codes. If you still can't find it, check the 17-digit VIN (Vehicle Identification Number) on the doorplate located on the passenger-side door frame. Provide this number to an Audi dealership staff member, and they can quickly retrieve the engine model from their computer system. This VIN can also be found in the 'Vehicle Identification Code' section of the vehicle registration certificate, making it very convenient.
Just check the vehicle license! The engine number section on the vehicle information page of the license clearly indicates the model, such as EA888. If you don't have the document with you, you can also open the engine hood and inspect the label on the engine block. The label is usually fixed on the front or side of the engine—just make sure it's not covered by dust or grease. In fact, every Audi TT comes with a silver aluminum vehicle identification plate on the right front door frame when it leaves the factory. Besides the VIN, you can also find the production date and matching engine information on it. The easiest way is to refer to the Certificate of Conformity provided at the time of purchase—the engine model and power parameters are all listed there, saving you the trouble of crawling under the car to find them.
Actually, the vehicle identification number (VIN) can reveal this information. For the Audi TT, the 10th digit of the VIN indicates the production year—for example, 'M' stands for 2021. Combined with the model codes 8N or 8S, you can determine the engine generation. The older 8N model used a 1.8T engine (BAM code), the mid-cycle 8S used a 2.0T (BPY/CCTA), and the newer models adopted the third-generation EA888. However, the most accurate method is connecting to the OBD diagnostic port to read the data, as repair shops typically have this equipment. Additionally, check the left front shock tower in the engine bay—Audi often places a white information label there, which includes the engine model. Of course, the simplest approach is to ask the original owner or check the insurance documents, as these records will have the details.
