It’s not about how many BMWs you own or how many years you have wrenched sir. It’s a simple matter of observation. They don’t arrive as pictured. At the very least they show up in a plain white box or a box with BMW designation on it not one that says Bosch all over it.
The pelican parts reference is somewhat misleading. They’re quoting a price for a genuine BMW part that bears the emblem. I believe Bosch is oem supplier and since yours is not a part wearing the emblem then yours is not BMW part.
