Why does my Audi A5's engine make a screeching noise?

Whenever I start my Audi A5's engine, there is a loud screeching noise that lasts for a few seconds before going away. What could be causing this and is it something I should be worried about?

There could be a few possible causes for this issue. One potential reason could be a loose or worn out drive belt. It's important to get this checked out by a mechanic as a worn drive belt can cause damage to other engine components if left untreated. I recommend bringing your car to a trusted mechanic for a diagnosis and repair.

Another possible cause could be an issue with the pulleys or tensioner. These components can become worn over time and cause a screeching noise when the engine starts. I suggest taking your car to a reputable mechanic for an inspection and possible replacement of the affected parts.

It's also important to check the fluid levels in your car, particularly the power steering and transmission fluid. Low levels of these fluids can also cause a noise when starting the engine. Make sure to check the levels and top up as needed.
