Oil level sensor leaking - time to replace the O ring

Has anyone replaced the O-ring on the oil level sensor on W204 C250? My car is a 2013.
Any tips or advise?
I know I need to drain the oil and remove the 3 bolts but I was wondering if there's more to it than just what I think.

You might want to double-check that the O-ring is leaking. The oil level sensor is at the lowest point of the car, and any engine oil leaks naturally gravitate to this point. I had a similar situation, but the culprit turned out to be a leak from the oil filter housing gasket.

I had the oil filter housing gasket replaced last week and I was told by the shop that another leak they saw from this oil level sensor. I was under the car and saw the leak myself. tt seems pretty straight forward job and will work on it next week.
Just ordered the O-ring and the sensor, may not need the sensor but still like to have it on hand.
I am hoping it's not the oil pan gasket.
