Why is the Audi A6 losing power while accelerating?

I've noticed that my Audi A6 is losing power while accelerating, especially on the highway. What could be causing this and how can I fix it?

It is likely that your fuel filter is clogged and needs to be replaced. This can affect the performance of your engine, causing it to lose power while accelerating. I would recommend taking your car to a certified mechanic to have this checked and replaced if necessary.

Another potential issue could be with your spark plugs. If they are worn out or dirty, they can cause a decrease in engine power. Consider replacing them and see if that solves the issue.
