1.9 TDI 4 PIN Dark Green / BLUE Coolant Temperature Sensor
This is also known as the ‘Temp Sender' and is used to measure the temperature of the coolant running through the engine
The most common symptom that this sensor is not working is when the engine is hard to start whilst warm. It will start up perfectly when cold, but takes a long time when warm. Also this can cause false readings on the coolant temperature gauge. Simply swapping this sensor (which takes around 5 minutes) will cure this problem
This coolant sensor is for the earlier models listed below and has the Square Shaped Plug, the later models have the D Shaped Plug
The sensor can be either blue or dark green from the factory, as per the picture
