To replace the battery on an Audi A3, open the bonnet and access the components underneath. In the central part of the engine bay, just below the windscreen, there will be a plastic cover that needs to be lifted to access the battery.

Disconnect the battery from the appropriate terminals and remove the securing bolts. This way, the battery can be extracted from its housing and replaced with a new part.

After installing the new battery, you can reinsert the plastic cover.
