Why is my Audi A3 making engine noise?

A high-pitched whistle could signal an intake leak or misaligned belt. Squealing can be traced back to a loose fan belt, and grinding might be a sign of brake problems rather than engine issues.

These include driving on a near-empty gas tank, flooring the gas pedal while the car is in Park, or slamming the gas pedal while the engine is still cold. Help sustain your engine’s performance and efficiency by staying miles away from these bad driving practices.

Can I put water in my Audi A3 radiator?
