What is the cause of the engine failure in an Audi 80?

I have recently encountered an engine failure in my Audi 80 and I am not sure what could have caused it. I have been regularly maintaining and servicing my car, so I am puzzled as to what could have gone wrong. Can anyone shed some light on this issue?

The most common cause of an engine failure in an Audi 80 is due to a faulty or worn out timing belt. It is recommended to replace the timing belt every 60,000 miles to avoid this issue. This is a crucial part of the engine and if it fails, it can cause serious damage to the engine and result in expensive repairs.

Another potential cause of engine failure in an Audi 80 is a malfunctioning fuel pump. This part is responsible for delivering fuel to the engine and if it fails, the engine will not receive enough fuel to run properly. It is important to regularly check and replace the fuel pump to prevent engine failure.
