Why does my Audi A5 produce low power output when accelerating?

I recently noticed that my Audi A5 seems to have a much slower acceleration than before. Even when I floor the gas pedal, the power output seems limited. What could be causing this issue?

One possible cause for this issue could be a clogged air filter. This can limit the amount of air flowing into your engine, leading to reduced power. Consider checking and replacing your air filter to see if it improves performance.

Another reason for low power output could be a malfunctioning fuel pump. If the pump is not delivering enough fuel to the engine, it can reduce power. Have a mechanic check your fuel pump to see if it needs to be replaced.

The issue could also be related to a faulty oxygen sensor. This sensor measures the amount of oxygen in your exhaust and helps determine the air-to-fuel ratio for optimal performance. A malfunctioning oxygen sensor can lead to decreased power and reduced fuel efficiency.
