Some reason the previous owner of my '05 525i cut off the o2 sensor connector for bank 1 going to the dme. I tried to use the bank 2 connector wire color to match them up but now I'm getting a p0151 code. Do anyone know where I can find an 02 sensor wiring diagram with the colors to make sure I wired it right?
