What is Audi TT OBD?
OBD, short for On-Board Diagnostics, is a computer system found in all modern vehicles, including your Audi TT. Imagine it as the “brain” of your car, monitoring various components and systems, and storing important data about their performance.

- Improving Fuel Efficiency: Your Audi TT’s OBD system constantly monitors fuel consumption and adjusts engine settings to optimize fuel economy.
- Ensuring Emissions Compliance: OBD helps ensure your car meets environmental regulations by monitoring emissions levels and alerting you to any potential problems.
