Why does my Audi A1's engine make a strange noise when accelerating?

I recently noticed that my Audi A1 makes a strange noise when I accelerate, almost like a whirring or grinding sound. This only happens when I'm pressing on the gas pedal, and it seems to get louder the faster I go. I'm concerned that there might be something wrong with my engine, but I'm not sure what it could be. Can anyone provide insight into this issue?

Your car may be experiencing an issue with the engine's timing belt. If this is the case, it's important to get it checked out as soon as possible, as a damaged timing belt can cause even more serious damage to the engine. I recommend taking your car to a mechanic to have it inspected.

Have you recently changed your air filter? Sometimes a dirty or clogged air filter can cause strange noises coming from the engine. Try replacing it with a new one and see if the noise goes away. If not, it could be a different issue.
