Acceleration Noise on 2001 Volkswagen Beetle

Whenever I step on gas for acceleration, I hear a loud rasping sound from engine area. What could cause this? Otherwise car runs fine.

Have the same car/problem. The mechanics just changed the water pump and the timer. MIL light came on and the noise. Please let me know if you get an answer.

Finally took car to dealer. Problem was the catalytic converter causing rattling sound. It was replaced and it corrected the problem. Thank goodness it was covered under warranty.
