How does the timing belt affect the performance of an Audi 80?

I've heard conflicting opinions about the importance of the timing belt in an Audi 80. How exactly does it impact the car's performance and what are the potential consequences of not replacing it?

The timing belt is a crucial component in the Audi 80's engine, responsible for synchronizing the rotation of the engine's crankshaft and camshaft. If it fails, it can cause serious damage to the engine and even lead to complete engine failure.
