could be the thermostat if its dropping.

coolant temp sensor is an easy job on a mk4, not sure about the mk5 but have a search for a guide will be one in existence.

They are somewhere between 25-30 from the dealers.

I have one for sale if your interested? I will need to check if the MK4 CTS is also used on the MK5...
