Ya that's BS.
Did a hard break-in on my M4c in June 2018. Zero issues ever.
Then did a hard break-in on my M3 in June 2021. Had the break-in service and no issues whatsoever. Almost 4k miles going strong now.
You have to remember: when euro delivery was an option, everyone was redlining their cars flat out until they hit the limiter on ze autobahn (with under 20 miles on the odometer).
