Why is the acceleration of my Audi A7 sluggish?

I've noticed that my Audi A7 has been experiencing sluggish acceleration lately. What could be causing this and how can I improve it?

One possible reason for the sluggish acceleration could be a clogged air filter. Try replacing it to see if that improves your car's performance.

Another reason could be a malfunctioning turbocharger. You may want to have it checked by a mechanic and possibly replaced if necessary.
