@@EGbeater Got it. Found all 4 connectors( upstream and downstream). Now I have to replace bank 2 upstream sensor as the dealer tested it and it is faulty. This explains why I am getting an error code of Bank 2 too lean and the 4/5/6 plugs are fouled. The bank 2 is getting too much fuel due to the bad O2 sensor.
Every damn BMW connector is a different puzzle! It's like they asked the vendors to come up with a new way on EVERY connector. Thank you!
thank you so much
Thank you!
You're welcome; hope it helped you out a bit.
what part of the car are these connectors located?
This helps to save on gas?
Does this 1 connection control all 4 of the O2 sensors in a F82 (S55)?
No, each O2 sensor has its own connector.
