Bluetec O2 Sensor locations?

2007 E320 Bluetec - Getting an open circuit error on the O2 sensor downstream of DPF (G3/1)

Need to know the location of the sensor as well as how hard it is to get to! Can I do it with a normal wrench, or do I need a special O2 sensor removal tool?

This gets a bit complicated with options changed between years and models, but go to and adjust to your car

BTW the car you have in your profile is not Bluetec
I have whole books of idiotics star can tell.
The best one is throttle code on diesels.
Or injector circuit error on 606 diesel with mechanical injectors.
Not saying it applies to your situation, but thing to consider.
