What are common engine problems in the Audi A7?

I recently purchased a used Audi A7 and am experiencing some engine issues. What are some common problems that may arise and how can I prevent them?

One common issue in the Audi A7 is oil leaks, which can lead to engine failure. To prevent this, make sure to have regular maintenance checks and address any leaks immediately.

Another issue is with the timing chain tensioner, which can cause severe engine damage if not addressed. It's important to have this part inspected and replaced as needed.
