Why does my Volkswagen Arteon have poor fuel efficiency?

I recently purchased a Volkswagen Arteon and have noticed that it is not getting the fuel efficiency that was advertised. What could be causing this issue and what can I do to improve it?

There could be several reasons for your Volkswagen Arteon's poor fuel efficiency. One common cause is dirty air filters, which can restrict airflow and decrease fuel economy. I would recommend checking and replacing your air filters if needed.

Another factor that can affect fuel efficiency is driving habits. Aggressive driving, such as rapid acceleration and braking, can significantly decrease fuel economy. I suggest driving more smoothly and avoiding unnecessary acceleration and braking.

It is also possible that your Arteon may have a mechanical issue, such as a faulty oxygen sensor or a clogged fuel injector. I would recommend bringing your vehicle to a certified Volkswagen mechanic for a diagnostic test to identify any potential issues.
