Its probably the coolant temperature sensor, which is on the engine. Not sure where abouts it is on a TDI, but I know on my 2.0L, its on the drivers side. If you take off the engine cover you can get to it easily. The sensors are known to fail. There is a newer sensor to replace it with, known as the "green top", meaning that the sensor is green. They are super cheap. $30 for the whole replacement (sensor, o-ring and clip). You can get it at the dealer or online somewhere like GermanAutoParts.com: GermanAutoParts.com

Yup, its on the coolant flange on the left (drivers) side of the head. If you're fast you can change it without losing much coolant.
