I have the following error code showing in VAGCOM


17664- engine coolant temp sensor (G62) open or short to plus
p1256 - 35 -10 intermittent

The only symptoms apart from the error code is than no and again the engine revs a bit high when I start up if the engine is already warm.

I'm told is the temp sensor shown in the picture below




Problem is there is no part number visible on the green bit :eek:

Van is a 2.5Tdi (2001) ACV engine code.

Is this the correct sensor for the above error code?
How do i find the part number?

Is it not like the oil sensors were you just order by colour

I don't think so?

I'm not even sure that this is the right sensor, I've just looked on VAGCAT and it describes the sensor shown in my picture as
"thermal switch / for switching off air conditioner / for trailer towing
105/112C 20MM 106/102C 4 pin green 3 stages / ":*

I was told that this was the sensor I needed to change but now I've no idea which sensor I've got to change
