What are Audi Engine Codes?

Audi engine codes, also known as Diagnostic Trouble Codes (DTCs), are alphanumeric codes that pinpoint specific malfunctions within your vehicle’s engine or related systems. These codes are generated by the On-Board Diagnostics (OBD) system, a computerized system that monitors various aspects of your car’s performance. When the system detects an issue, it stores a corresponding code which can then be retrieved using an OBD-II scanner or code reader.

Why are Audi Engine Codes Important?

• Diagnose Problems Quickly: Instead of relying on guesswork, you can pinpoint the source of the issue, saving time and money on unnecessary repairs.

• Maintain Your Vehicle Effectively: Regularly checking and addressing engine codes can help keep your Audi running smoothly and extend its lifespan.
