Sensor on the thermostat housing ???

[Colinspence]

So I’m trying to get the fans working
On my 2.0 tdi 140
Iv replaces the fans ..
Going to replace the thermostat
And Iv found a sensor that plugs into the housing ...

Is this another temp sensor (exactly the same as the coolent gauge sensor )??
As I can’t find a name for it anywhere not even in the Haynes Manual and I want a new one so make sure I can sort this none fan working problem out when it’s up to temp

Yes. 2 sensors, on my car, one on the main thermostat housing and one near the inline stat above my dsg. Both are grey and held in with plastic u clips

Thanks.
So I’ll order the same sensor again and hope it finally works.

Iv changed the sensor. And the thermostat but still the fans won’t come on when up the temp ?

Is there a fan relay or a fuse ??
Iv checked all the fuses and can’t see any blown

Finally sorted it after blood sweat and tears 
It just jumped into life after a drive
