Why isn't my 2016 Audi A7 2.0T starting?

When turning the key, the engine does not start but the headlights and dashboard lights seem to be working correctly.

One possible reason for your Audi A7 not starting could be a faulty starter motor. It is responsible for starting the engine, and if it is not functioning properly, you will not be able to start your car. It is recommended to have a mechanic inspect and potentially replace the starter motor if necessary.

Another possibility could be an issue with the car's battery. If the battery is low or dead, it may not have enough power to start the engine. Check the battery and if needed, have it replaced.
