What should I do when my Audi A2 starts making a strange noise?

I've noticed that my Audi A2 has started making a strange noise while I'm driving. It's not a continuous noise, but it happens intermittently. What could be causing it and what should I do?

It's important to get your car checked by a mechanic as soon as possible. Strange noises can be an indication of a larger issue that could lead to more costly repairs if left untreated.

Check the engine oil and other fluids to make sure they're at the proper levels. If they're too low, it could be causing the noise.
