Emblem is definitely not original BMW part! The edge is processed cheaply and has quirks! The print is frayed especially at the edges of the letters. Besides, my emblem came despite protective film scratched with me! Long-term testing is still pending. Hope it does not dissolve the first wash!
Conclusion: Who is on BMW quality, should rather invest a few euros more and buy the BMW dealer! The second point I have forgiven because the diameter of the original corresponds to the assembly and also worked well!
