Why is my Audi A6 experiencing a decrease in acceleration?

I've noticed that my Audi A6 is not accelerating as quickly as it used to, even when I press down on the gas pedal. What could be causing this issue?

It is possible that your car's air filter is clogged, which can affect the engine's performance and reduce acceleration. Try replacing the air filter to see if that improves your car's acceleration.

Another potential cause could be a dirty or faulty fuel injector, which can lead to insufficient fuel being delivered to the engine. Consider getting your fuel injectors cleaned or replaced to see if it improves your car's acceleration.

You may also want to check the condition of your spark plugs and wires. Worn out or damaged spark plugs can impact engine performance and cause a decrease in acceleration. Replacing them may help improve your car's acceleration.
