What are the common causes of engine failure in an Audi A2?

I am looking to purchase a used Audi A2 and want to know what potential red flags to look out for when assessing the vehicle's engine. I want to make sure I make a well-informed decision.

The most common cause of engine failure in an Audi A2 is a faulty fuel pump. This can lead to issues with starting the engine or sudden loss of power while driving. It is important to have the fuel pump checked during regular maintenance and replaced if necessary.

Another common cause of engine failure in an Audi A2 is a failing timing belt. If the timing belt breaks, it can cause significant damage to the engine and result in costly repairs. It is recommended to have the timing belt replaced every 60,000-100,000 miles.
