New Coding After Battery Replacement in the Audi A3

Model: Audi A3 8V, MK 3 - Years 2012-2019
Part: Battery

Every time you replace the battery in a modern vehicle, particularly in this Audi, you must perform a recoding and a reset using a diagnostic system like VCDS. Connect the diagnostic system to the vehicle's OBD port, identify the model, and wait for the data to load from the ECU. Then, enter the battery details such as the brand, serial number, and amp rating. After each step, click 'OK'. This way, the coding will be completed.
