Where is the Audi OBD port located?

[VonTanner]

Audi's OBD port is located under the dashboard on the driver's side, and you can see it by pulling the lever for the front hood. Here is some additional information: 1. Function: OBD refers to the On-Board Diagnostics system, which allows reading vehicle data and detecting fault codes using an OBD scanner. Its main functions include: diagnosing faults affecting emission performance; displaying faults via an alert system; identifying potential problem areas and providing information for offline communication. 2. Principle: OBD connects various emission-related component information to the Electronic Control Unit (ECU), which has the capability to detect and analyze emission-related faults. When an emission fault occurs, the ECU records the fault information and related codes, and alerts the driver via the malfunction indicator lamp. The ECU ensures access to and processing of fault information through a standardized data interface.
