Why does my Audi A6 make a squealing noise when I start the engine?

I've noticed that whenever I start my Audi A6, there is a loud squealing noise that lasts for a few seconds before fading away. Is this normal or is there something wrong with my car's engine?

This could be due to a loose or worn drive belt that needs to be replaced. We recommend bringing your car to a certified mechanic for a thorough inspection and repair if needed.

It could also be a sign of a failing alternator or a loose pulley. We suggest having a mechanic check your car's electrical system and pulleys to determine the exact cause of the squealing noise.
