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

I recently experienced engine failure in my Audi and I'm wondering what the possible causes could be. I want to be better prepared and informed for future maintenance and potential repairs.

One of the most common causes of engine failure in Audi vehicles is a failed timing chain tensioner. This is due to a design flaw that causes the tensioner to wear out prematurely, leading to engine failure. It's important to have this part replaced during routine maintenance to avoid potential breakdowns.

Another common cause of engine failure in Audis is a faulty high-pressure fuel pump. This can lead to a loss of power and eventual engine failure. If you notice a decrease in power and performance, it's important to have your fuel pump checked and replaced if necessary.

Worn out spark plugs and ignition coils can also contribute to engine failure in Audi vehicles. These components are responsible for creating combustion in the engine and when they become worn or damaged, it can lead to misfires and eventual engine failure. It's important to replace these parts at recommended intervals to prevent breakdowns.
