Why is my Audi engine making a whining noise?

I recently noticed that my Audi's engine has started making a strange whining noise. It seems to occur more frequently when the car is idling or at low speeds. What could be causing this and should I be concerned?

It could be a sign of a worn out belt or tensioner. I recommend taking your car to a trusted mechanic for a thorough inspection.

Is your car due for an oil change? Low or dirty oil can also cause your engine to make strange noises. Make sure to follow the recommended maintenance schedule for your Audi.

If your Audi has a turbocharged engine, the whining noise could be a result of a faulty turbocharger. You should have it checked by a mechanic as soon as possible to prevent further damage.
