So I had a check engine light come on, pulled the codes on my MAC scanner and got a p0050 heater curcuit malfuntion bank 2 sensor 1 ....... where is bank 2 on a 1.8t motor? The a/f sensor could also explain the reoccuring p1136 but the bank 2 through me through a loop lol. My question is why when I do a search do I not find any other people with this code on a b5 1.8t? Is it my scanner?
