How to fix a loud noise coming from the Audi 80's engine?

My Audi 80 is making a loud grinding noise whenever I start the engine. It only goes away after a few minutes of driving. What could be causing this and how can I fix it?

This could be due to a faulty timing belt or a worn out engine belt. It's important to get this checked by a mechanic as soon as possible to avoid further damage.

It might also be caused by a loose or damaged pulley or tensioner. It's best to take your Audi 80 to a trusted mechanic for a more accurate diagnosis and repair.

Make sure to check your engine oil level as well as it could be low and causing the noise. If that's the case, simply topping up the oil should solve the problem.
