You don't know Czech authorities, they are able not to register your car just because one part of the equipment is different. Trust me, we have much more strict laws when it comes to cars than Poland. Another one I found was this: http://allegro.pl/bmw-335i-e92-coupe-m-pakiet-i3527646882.html VIN: WBAWB73527P023315 But it's quite suspicious because clearly some equipment was replaced (new iDrive etc.) which could mean a reworking after crash.
