Why does my Audi A3's engine feel sluggish?

I've noticed that my Audi A3's engine has been feeling sluggish lately, especially when I accelerate. Does anyone have any ideas on what could be causing this and how I can fix it?

It's possible that your engine air filter is dirty or clogged, which can restrict air flow and cause decreased performance. I would recommend checking and replacing the air filter if necessary.

Another potential issue could be a problem with your fuel injectors. If they are dirty or malfunctioning, it can affect your engine's performance. You may want to consider getting them cleaned or replaced.

Have you recently had your spark plugs replaced? Worn or faulty spark plugs can also cause a decrease in engine power. It might be worth checking and replacing them if necessary.
