What are some common problems with Audi engines?

I recently purchased an Audi and have been experiencing some issues with the engine. Can you provide me with some insight on potential problems and how to address them?

One common issue with Audi engines is carbon build-up, which can lead to misfires and reduced performance. To prevent this, make sure to use high-quality fuel and get regular engine cleanings.

Another potential problem is with the timing chain, which can stretch or break over time. It's important to get this inspected regularly and replace it if necessary to avoid more serious engine damage.

Leaks in the coolant system are also common in Audi engines, which can lead to overheating and engine damage. Be sure to regularly check and replace coolant, and address any leaks immediately.
