Where is the engine model number on an Audi TT?
2 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.
