Does anyone have the part number for the O2 sensor on these I5 engine ? I mean the generic one. I don't mind splicing the wires.

Just go to any of the import parts suppliers (bimmerparts.com -- blau) and look for a universal Bosch or generic to fit your car. there isn't much difference in them and only require a wire splice. I see there is a deep socket now available with a slot in the side, made for these sensors. The 5000 is an easy fix in about 30 minutes.

Not sure if there is more than one.
