Does the battery replacement require recoding? I cannot find a definitive answer

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. For your TTS Quattro, replacing the battery typically requires recoding. Many modern Audis, including the TTS, are equipped with a Battery Control Module (BCM) that monitors the battery's condition and charging. When you replace the battery, the BCM needs to be informed of the new battery's specifications to ensure it charges correctly and efficiently. There are cases where replacing the battery with an equivalent battery could work without coding, but you may not have ideal charging, and the battery's life may be shortened. If you need more advice, have any other questions about your vehicle, or would like to get connected to a RepairPal Certified shop near you, we have you covered.
