I’ll stick to H‑E‑B, Costco, Sam’s Club, AM/PM, as I have for forty years of driving, and will only consider any form of fuel injector cleaning upon an issue arising. Across multiple brands/engines & multiple 80-100k+ runs, never had a single issue. BMW engines are no different. (There’s a reason no manufacturer actually recommends anything, only stealerships, conveniently not covered either). 98% of the time it’s a money grab. To each their own though, hell, I follow 5-7k OCIs with routine oil analysis, so, yea. We can all spend where we deem it useful. /shrug.

Or maybe they do
