What are the most common causes of engine failure in the Audi A4?

I have recently purchased an Audi A4 and want to ensure I properly maintain it to avoid any potential engine failures. What are the main reasons why the Audi A4's engine could fail?

One of the most common causes of engine failure in the Audi A4 is due to lack of regular maintenance. It is important to follow the recommended service schedule and check your engine oil levels regularly.

Another common cause of engine failure is overheating, which can be caused by a faulty cooling system or lack of coolant. Be sure to have your cooling system inspected and coolant levels checked regularly.

Using the wrong type of oil or not changing it frequently enough can also lead to engine failure. Make sure to use the recommended oil for your Audi A4 and change it every 5,000 miles or as recommended by the manufacturer.
