TDI 184 main fan comes on a lot, where is CTS? -

Hi all, my main cooling fan comes on when it likes, sometimes 30 seconds after running the car! Never overheats, temp gauge rises to the middle and stays there! My mechanic read the codes and said Coolant temp sensor no.2 shows no reading, and is U/S!

I have bought both CTS anyway, PN 059919501a, the smaller one, and the other, PN 8170794RMP

Where are these located, and are they easy to swap out? cheers

Is it diesel? 

Could be the car doing a dpf regen.

no, its 2.0 TDI, as stated, car always gets motorway runs, and occasional fuel additive!   Mechanic said CTS no. 2 has failed!
