Today we will explain how to replace the alternator on a 2014 Audi A3 car. Before performing the alternator replacement, it is necessary to disconnect the negative terminal of the battery in order to deactivate the voltage inside the vehicle. Immediately after, we remove the front wheel on the passenger side to have more space to perform the replacement; we lift the car using jack stands.

We unscrew the screws on the fender to remove it. We loosen the fixing belt by removing the tensioner with the help of a M16 wrench. We remove the distribution belt and proceed with the disassembly of the alternator.

We unscrew the screws that fix it to the compressor and disconnect the power connector. We then remove the element and insert the new one. After completing the assembly, we insert the belt and tensioner and then mount the front wheel and start the vehicle to test the operation.
