BMW Repair: Coolant temperature sensor location., coolant temperature sensor, 2000 bmw 323ci

Question
I was told the coolant temperature sensor is on the intake side by #6 cylinder. I also have a sensor located in the lower radiator hose. When I looked the part up it said the sensor is located in the lower hose. The picture they show is the same as the one in the lower hose. I'm trying to find the right location of the sensor. Do you have any ideas where the sensor is located and what the sensor in the lower hose is? This is on a 2000 BMW 323CI M52 engine. Any help would be appreciated.

Answer
I am not sure why you need to replace the sensor.The sensor in the lower radiator hose is the coolant level sensor.The coolant sensor for the fuel injection is located as you stated under the intake runner.To gain access you need to remove the intake that is probably why you didn't see it.
