The service bulletin called out other engines:

N51, N52K, N52T and N55 Engine: Various Faults Stored in DME Related to VANOS and Camshaft

Maybe Silenus can speak to those?
It will be the other engines as well. They are much much less common than the N55, likely because they are under less stress (lower performance category). We do see them though. 02/10-12/10 N55s are constantly in rotation at the shop. It's as simple as someone deciding to put 8 bolts on the car that are the wrong tensile strength. Million dollar mistake.
