What are the common causes of failure in Audi 80 engines?

I've been experiencing frequent engine failures in my Audi 80 and I'm wondering what could be the cause. I've kept up with regular maintenance and oil changes but it still keeps happening. Any ideas?

The most common cause of engine failure in Audi 80 models is a faulty timing belt. It's important to get this replaced regularly to avoid any major engine damage.

Another common cause of failure could be a defective fuel pump. This can cause strain on the engine and lead to frequent breakdowns.
