What is the most common cause of engine failure in a Audi 80?

I have recently noticed some performance issues with my Audi 80 and I am now concerned about the possibility of engine failure. What are the typical reasons for this type of issue and how can they be prevented? Any help would be greatly appreciated.

The most common cause of engine failure in an Audi 80 is typically due to a lack of regular maintenance, such as changing the oil and filters. It is important to stick to your car's recommended maintenance schedule to ensure the engine is running smoothly.

Another frequent issue that can lead to engine failure is overheating. Be sure to regularly check your coolant levels and have your cooling system inspected to avoid any serious damages.

In some cases, engine failure can be caused by an issue with the spark plugs or ignition system. It is important to have these components inspected and replaced when necessary to avoid potential problems.
