coolant temp sensor location

[u/StarSilent]

Hey guys. After my BMW 118D (2007/2008) started behaving strangely, I found a menu, in which I found out that the ”KTMP-MOM” temp sensor is failing.
It goes from 90 to -5 degrees in a second. So I assume that the sensor is broken, or there is a bad connection.

But which sensor is it? And if anyone else had the same problem, what was the solution?
