SOURCE: MY WILL NOT START THE CAR C240 MERCEDES BATTERY IS NOT DEAD

I am assuming that the engine won't even turn over. could be lots of different things. The simplist is to make sure the car in in PARK , won't start if not. Other things could be , Security imobilizer if you have one. Does your key have a electronic chip in it ? Try your other set of keys if you have one. Check if battery connections are clean and tight.

SOURCE: How To Change Oxygen Sensors in 2002 Mercedes C240 Sedan?

I do not know the part numbers but you have 4 sensors. 2 pre and 2 post catalytic converter. The pre sensors are the most sensitive and are generally the ones to fail. the rear sensors usually have a heater circuit problem. If your just replacing them for routine service interval I would just do the fronts. They connect to the engine wire harness in the front of the transmission pan. You may need an o2 sensor socket to remove the fronts. They are just a 22mm. in size.
