There are plenty of internal notes that change the N55 over the years, BMW knew its a problem and slowly pushed changes in the engine to the later 2012 and F-chassis engines.
Just pray that BMW did not use the same rod bearing tolerances in the 2010/2011 N54.
2010/2011 was the year they switched suppliers for the rod bearings and that's why you see so many 2011 M3's and 2011 N55 cars blowing up.

Oh yeah uh 335is N54 (actually N54T) might be affected? That sucks.
