Hi, this is my first post and also first bmw, so be gentle.

Bmw e92 320i 2008, I purchased a cheap obd reader and read a code on my car because it was killing my fuel, more than it normally should.

I received the following codes

P126E
P114C
P2273

All of them related to bank 2 sensor 2, what had confused is as far as I know, my car only has four cyclinder therefore only 1 bank?

Would anyone be able to elaborate on where I can find bank 2 sensor 2?

Thanks in advance

Mike
