What are the common problems with the clutch in an Audi 80?

I recently purchased a used Audi 80 and I am experiencing some issues with the clutch. The car is having trouble shifting gears smoothly and there is a noticeable noise when engaging the clutch. What could be the cause of this?

The most common problem with the clutch in an Audi 80 is a worn out clutch disc. This can be caused by constantly riding the clutch or aggressive driving. It may be time to replace the clutch disc.

Low or contaminated clutch fluid can also be a cause for difficulties with the clutch. Check the fluid levels and quality, and consider flushing the system if necessary.
