What are the common issues faced with the Audi 80's turbocharger?

I recently purchased a used Audi 80 and I've noticed some unusual noises coming from the turbocharger. I want to know what are the most common problems with these turbochargers and if there are any specific steps I should take to maintain it properly.

The most common issue with Audi 80's turbocharger is a boost leak, which can cause a drop in performance and increase in fuel consumption. It is recommended to regularly check the hoses and clamps connecting to the turbocharger and replace any worn out parts immediately.
