Is the aircon switched on when this happens?
Is the ambient temperature quite high where you are?
Have you had the car scanned for any errors?

Have it scanned for errors and work from there.
It would help to say in what area you are in so we can advise where to go.

It is your thermostat. Sounds unlikely but believe you me. I had a Golf 5 and Jetta 5 with 2.0litre engines 85kw and had the same problem with both. Occured around the 150 000km mark. I changed the thermostat after changing the coolant sensor which were relatively cheap, had the Management system reset and problem solved. Your diagnostic system will through the error code for the coolant sensor. Like I said it sounds unlikely but thats what i thought too until I have tried everything and out of pure frustration decided the replace the thermostat. Good luck.
