I have had cars that were over 10 years old 100,000 miles on them that never got flushed except for a little when bleeding after brake job ,never a problem.
Given the price of BMW parts and the fact we a talking about maybe $10 in brake fluid and how simple it is to bleed brakes I Will continue to do it even after the warranty ends
With that kind of mileage a flush may have been a bit over the top but a bleeding at all four corners would most definitely been in line time wise. Sealed system or not they will "soak" up some moisture and air...even a small amount of contamination will eventually take it's toll on performance and the life span of the brake components.
