Why is my Audi A6 losing power while accelerating?

I've noticed that my Audi A6 has been losing power while accelerating, particularly when I'm driving on the highway. It used to have good acceleration, but now it struggles to reach high speeds. I'm wondering what could be causing this issue and if there's anything I can do to fix it.

It's possible that your spark plugs or fuel filter may be dirty or clogged, leading to a loss of power. I recommend getting these components checked and replaced if necessary.

Another potential cause for power loss in an Audi A6 could be a faulty oxygen sensor. This sensor helps regulate the air-to-fuel ratio and impacts engine performance. It's best to have a professional mechanic diagnose and replace the sensor if needed.
