2012 S550 4M O2 sensor change
So Bank 1 Sensor 1 needs replacement. Any advice please? Do I need to take it in? Have it lifted? Or is it a driveway diy job? Any specific tools?
Also, after the change does the CEL go out or do I need to have it reset?
Thanks

I guess the most obvious question is how do you know which sensor to replace? Do you have access to SDS or similar to read out fault codes? If you have a CEL then you have thrown a code that will need to be cleared. I don't have any direct knowledge to share on replacing O2 sensors but am attaching WIS instructions for you to follow. Seems easy enough. (Are we sure that we are talking about O2 sensors?)
Good luck,

Ok, I finally got it done, and the P2626 code is gone after replacing my O2 sensor (Bank 1 Sensor 1 upstream in my case).
Below I attached a guide I made on how to change this sensor, it's simple on paper but working in tight spaces makes things very hard.
Good luck and let me know of any questions!!
