Tako je in izraz OEM res velikokrat napačno uporabljamo, oziroma ga enačimo z OE. Pa ju ne bi smeli.
Dajmo enkrat tole razčistiti, lepo prosim:
OE = original equipment, torej "Original BMW Parts" v našem primeru
OEM = original equipment manufactured, proizvajalec originalne "robe" (za BMW v našem primeru), recimo BOSCH, Hella, Lemförder, Sachs itd.
There's a big difference between OE, OEM, and aftermarket, and if you want to be a smart consumer, you should really learn what the differences are. It's not just wording.
OE = Original Equipment - exactly what is used on the assembly lines when your car was made. Parts were made by the exact same manufacturer, to BMW's specifications, and are usually stamped with the BMW logo. These parts must also meet all the BMW quality control specs for that part, same as any part that's accepted into the production process.
OEM = Original Equipment Manufacturer - parts are made by a manufacturer that supplies original parts to BMW. These parts do not have to pass the BMW quality control tests for that part, and do not have the BMW logo on them. Quality of these parts can vary greatly - they can range between the exact same part as the one that's put on the car on the production line (but minus the BMW logo...), to something that wasn't good enough to pass quality control, so the manufacturer just sells them as OEM. Another issue - the part may be made by a manufacturer that supplies parts to BMW, but that part may not be a part that particular manufacturer supplies. For example, ZKW may supply some of the OE lights to BMW. However, if they felt like it, they could manufacturer suspension components, and label them "OEM" - after all, they are an Original Equipment manufacturer, just not for suspension components.
Aftermarket - anything goes. Caveat Emptor.

+ da prvovgradni OE deli zdržijo še cca 30% dlje od OE delov, ki jih kupimo kasneje na pooblaščenih servisih
+ nekateri prvovgradni deli nimajo BMW kataloške in bi jih lahko smatrali za OEM - recimo DSC enota. Cene teh delov so navadno skoraj identične OE delom.
To je tudi odgovor na naslov te teme, nadaljne diskusije o konkretnih primerih/delih pa utegnejo biti res obsežne.
