What are the common issues with the Audi A5's turbocharger?

I've noticed a decrease in performance and unusual noises coming from my Audi A5's turbo. Is this a common issue and what steps should I take to address it?

It is not uncommon for the Audi A5's turbocharger to experience issues, especially at higher mileage. I recommend immediately checking your vehicle's oil and replacing it if necessary. Additionally, have a mechanic inspect the turbo's components such as the seals and bearings to determine the root cause of the problem.
