Got this code on my 2010 E350, it has 80k on it.
As soon as the car is turned on, radiator fan is running at full speed. And coolant temp gauge reading is not even at 50 C.
My E350 have been running fine till 3 months ago, CEL light came on. Took it in to our local mechanic.
Initial report was;
1) Cylinder 6 misfire (replace spark plugs)
2) Car coolant temperature reading low ( stuck or lazy thermostat, replace with new one)
3) flush coolant. Change air filters (spark plugs and filters are still original ones)
I didn't feel like paying $1800 for those services, so I did all above services with OEM parts from FCP.
Took about 3-4hrs and everything went smoothly.
The car ran fine for about 3 months and now two new codes popped up.
I love the Mercedes, and cabin is the quietest interior of all 8+ cars I've owned.
But reliability is lacking compared to my 03 Accord EX with 350k miles on it, still going strong
W212 - I've managed to squeeze my hand behind the engine and find the sensor. I've even manged to remove the wiring clip but I cannot, for the the life of me, wiggle the sensor out free. I can spin it, wiggle it but it will not come out from the block. Is there a clip similar to the W211 that keeps the sensor in place?
Engine temperature sensors are screw into the blocks and you need good wrench to get them out.
I have different engine, but I save any sensor chart I can find on the net, so google it for your engine.
This is what I found very handy for my application.

Hi. Thank you for the reply. My coolant temperature sensor does not have threads. Just a rubber washer. That's why I was asking if there is a second clip holding the sensor to the block.
I have been trying to remove the screw that holds the temp sensor in place at the rear of the cylinder head. I think my hand is just too big. I even tried with a mirror. Has anyone successfully removed the screw, and if so- how did you do it? Not finding any videos or resources. Thanks

If you engine is M276 3.5 NA , the water temp sensor ( item 3 ) location is under the plastic hose ( item 1 & 2 ) going to HVAC heater core.
If M276 3.5 NA ( or my M276 3.0 TT too ) It seems you need to remove the plastic pipe no 1, no other way.
