What are some common causes of sudden engine failure in Audi cars?

I've been experiencing sudden engine failures with my Audi A4 and can't figure out what's wrong. Any insight on what could be causing this issue?

One of the most common causes of sudden engine failure in Audi cars is a faulty fuel pump. It's responsible for delivering fuel from the tank to the engine, and if it fails, your car will come to a sudden stop. Make sure to have your fuel pump checked regularly to avoid this issue.

Another common cause is a malfunctioning spark plug. Spark plugs are responsible for igniting the fuel in the engine, and if they fail, your car won't be able to start or keep running. If you're experiencing sudden engine failures, have your spark plugs checked and replaced if necessary.
