Hello, Simply questioning if anybody has modified o2 sensor 2, financial institution 1 and is it tough to get to? Are there any threads on this already? Tried looking out however didn’t discover something (may very well be me).
Automobile is a 2015 220d which has began white smoking extra. Not too long ago had EGR Cooler changed underneath the recall. OBD scanner comes up with the next code and message.
P22AE: Management unit: Engine management unit.
Heated oxygen sensor (HO2S) 2, Financial institution 1 – Reference voltage – Open Circuit
Additionally comes up with 284E00
I’ve cleared codes however they arrive straight again on as quickly as you drive. Sensor 1 is simple from above however I am guessing sensor 2 must be finished from beneath.
Any recommendation vastly appreciated as I am attempting to keep away from the dealership, though the DTC code was not there earlier than they modified the EGR cooler.
