You can replace the battery on the Audi A3 by opening the bonnet to access the components inside the engine bay: here you will find the device on the right side of the bay. You will need to completely free it from the fixing screws and the appropriate power cables connected to the two terminals of the battery.

Once the device is fully freed, you can remove it from its seat to insert the new replacement part.

The latter can now be connected and secured properly to ensure everything functions.
