[Solved] Locating the Internal Temperature Sensor in Mercedes W212 - Error A2208300772

Hello
I've had a pretty big problem since a week.
The diagnostic computer shows an error of the temperature sensor inside the vehicle - it shows the temperature of -50 ° C all the time.
Through this sensor, hot air flows from the rear vents all the time in the car on warm days. Nothing can be set
I replaced the sensor at the ignition switch - so small with a fan, but it turned out to be a temperature sensor in the cabin.
I entered the password for the interior temperature sensor of the vehicle w212 in google and I got a lot of sensors with the number A2208300772
It is a small black sensor with a characteristic curve. Unfortunately, it is an evaporator temperature sensor mounted under the console glove box - the dashboard.
Does anyone know where I can find this temperature sensor inside the vehicle?
In the W211, it was in the rearview mirror from what I remember. I do not see anything similar in W212 :(

Thanks in advance for your correct answers.

It helped?

This is called - "Cab temperature sensor" - with a fan.
There are 7 sensors in total.
1. It's the temperature in the cabin in the photo
2. Evaporator temperature sensor

3. Left air supply temperature sensor
4. Right air supply temperature sensor
5. Temperature sensor front left on the feet
6. Temperature sensor, front right, on the feet
7. Interior temperature sensor of the vehicle

I'm looking for the last one.
He's not working. If the sensor is damaged or not connected, the computer gets info with a temperature of -50 ° C
The computer reads the wrong value and opens the reheat.

To all the "masters" of the world.
The problem was solved by the Mercedes Benz service in Leszno (Greater Poland) Duda Cars.
No sensor was the cause.
During the operation of the car, a plastic guide, mixing warm and cold air (applies to zone air conditioning), has become detached.
A plastic element connecting the motor with the flaps - regulating the opening of the flaps on the heater on the right side.
Problem solved.
