How can I properly maintain the turbocharger on my Audi A4?

I recently purchased a used Audi A4 with a turbocharged engine and want to make sure I am properly maintaining it to ensure longevity and optimal performance. What steps should I take to properly maintain the turbocharger?

Regularly change your oil and use high-quality synthetic oil. This will help keep the turbocharger lubricated, reducing the risk of issues.

Avoid prolonged idling and hard acceleration, as these put extra strain on the turbocharger. It's also a good idea to let the engine cool down after driving before turning it off.

Keep an eye on your boost pressure and make sure it stays within the recommended range. A drop in boost pressure can indicate a potential issue with the turbocharger.
