If you used your VIN to look up that part…any items in the illustration that are grayed out indicates they ARE NOT for your car. This goes for the part nbrs below the diagram, too…any that ARE NOT listed means they aren’t used on your car.
It appears that only item #11 is for your car in that diagram since everything else is grayed out.
Also, BMW part nbrs have 11 digits “xx xx x xxx xxx”…it doesn’t look like anything on the QR code sticker is a BMW part number. Some times on smaller items…BMW will use just the lat 7 digits of the part nbr (x xxx xxx). The QR sticker is probably for the MFG that supplied the part to BMW.
Your OBD II diagnostic connector is
X6 in the illustration below and is obviously attached to something else. You need to remove more stuff down there to find out what it’s actually attached to.
