I have changed a few cylinder heads under warranty for this type of problem. The exhaust valve guides wear, this causes the exhaust valve to seat badly, giving low compression. if one cylinder compresion reading is more than about 50 psi below the others, then this warrants head removal. It is quite a job, due to the fact that the camshft id chain driven. If you are up for it then once the head is removed, poor liquid into the exhaust ports and see if it leaks out through any of the exhaust valves.

this sounds like a thermostat fault, but also could be the sensor switch to the radiator but is more likely the thermostat, it should be located at the front top of engine, follow the top water hose to the engine and you will find the thermostat housing, also just a heads up, these had a problem when first made, according to the known fixes and problems with VW's the hoses corroded inside and started loosing water, this could be wise to get the system presure checked to...hope this helps
