O2 sensor P0161 - which one?

Hello guys, I got 1998 C43 AMG.
I got check engine light couple times, when I scan it I get P0161 code: Oxygen Sensor Heater Circuit Bank 2 Sensor 2.
Can somebody tell me which one it is exactly, right or left (please explain which side is right which is left : )) and if its before cat or after cat.

Maybe somebody had this issue and know what exactly is wrong...
I was at the dealer doing some service and the light came up again and they scanned it again and they said its O2 sensor and misfire codes: P0161, P0141, P0300, P0306, P0307, P0308 but when I scan it at AutoZone I just get P0161.

Greatly appreciate any help
