Audi Diagnostics refers to the process of using specialized tools and software to diagnose problems with an Audi vehicle. This process involves connecting a diagnostic tool to the vehicle's on-board computer, also known as the Engine Control Module (ECM) or Powertrain Control Module (PCM), in order to read and analyze diagnostic trouble codes (DTCs) that may be stored in the vehicle's computer.

These codes can indicate various issues such as a malfunctioning sensor, a problem with the engine or transmission, or an issue with one of the car's many electronic systems.

At Melbourne Euro, Audi diagnostics can be done by trained and certified technicians using specialized diagnostic tools and software, which can communicate with the vehicle's computer systems and retrieve information about various system status, sensor readings, and error codes. This information can then be used to identify and diagnose any problems with the vehicle, and to develop a plan for repairs or maintenance.

The use of Audi diagnostics is a very important tool for identifying and resolving problems with an Audi vehicle, as it allows for a more accurate and efficient diagnosis of issues, which can save time and money in the long run.
