What is the cause of Audi's 1.8T engine failures?

I've heard about a lot of issues with Audi's 1.8T engine, but what is the root cause of these failures and how can they be prevented?

The main cause of Audi's 1.8T engine failures is due to the design of the engine's oil system. The oil pickup screen and oil pump are prone to clogging, leading to a lack of proper lubrication and eventual engine failure. To prevent this, it is crucial to regularly change your oil and use high-quality, synthetic oil.
