Thank You very much, it's g62 and seems to be quite difficult place to change. I let you know, how I replaced it.

Generally, the radiator outlet sensor just turns on after run fans. The coolant temp sensor is the one controlling gauges, ECM.

The o rings stick to the sensor and the body. Put a wrench on the plastic wire housing and twist, that breaks the o ring free. Some have had better luck with the engine slightly warm, not cold or hot. Always use new o ring. And put silicone grease on the o ring.

I changed temperature sensor but it didn't resolve my problem. Problem is that radiator fan starts blow full blast allways when I start car even the engine is cool. Fan stops after I stop the engine. Only when the Webasto is on, radiotator fan don't blow. Webasto has installed just before when I noticed fan problem. Can webasto cause this kind of problem or is it the fan control module broken on something else?

Check on the coolant pipe that goes from the top of the EGR valve. Should be there
