How to Replace Oxygen Sensor on 2013 W212 E550 4Matic
I Need help replacing O2 sensors on my 2013 E550 4Matic. Does anyone have photos or diagrams of location on these sensors?

There are 2 front wide band before CAT and 2 rear narrow band o2 sensors after CAT
They are both at the exhaust system.
Need to lift up car to see them.
Some engines need its exhaust system to be loosened and drop a bit to access o2 sensors.
Yours is M278 engine , yes ?
If M278, very similar to M157, watch this video and observe the o2 part
