How do I troubleshoot a malfunctioning electronic throttle control in my Audi A2?

I recently noticed that my Audi A2's electronic throttle control is not working properly. It's not responding as smoothly as it used to and sometimes I have trouble accelerating. What could be the cause of this issue? Is there anything I can do to fix it?

First, try checking the throttle body for any debris or dirt that may be blocking its movement. If that doesn't solve the issue, it could be a problem with the accelerator pedal sensor. I suggest getting that checked by a professional.
