DI is more prone to carbon buildup than port or dual injected. Just be religious in oil changes(I never follow 10k change interval recos & stick to 5 for the normal daily... annually for the less used) & be mindful of gas quality, you'll be fine.
Bimmers are known to require periodic intake cleaning. Walnut blasting is the most ideal method.
