Why is my Audi A6 accelerating slowly?

I've noticed that my Audi A6 seems to be accelerating slower than usual. I've checked the engine and everything seems fine. What could be causing this?

One possible cause could be a clogged air filter. Try cleaning or replacing it as it can affect the air flow to your engine and decrease acceleration.

Another possibility is that your spark plugs may need to be changed. Worn out spark plugs can lead to inefficient combustion and result in slower acceleration.
