@byjoshuawilliams find the fan thermostat switch on the radiator and bridge the wiring to see if the fan runs, then if that is OK make sure that part of the radiator is getting hot, thermostat opening/rad blocked etc. Fan switches are very common on VW's I used to fit loads of them when I worked at VW/Audi before my BMW days.
