Straying a little - Grizz if you are still fault finding this and the Golf is a MK4, it's a known fault I believe. Fan faults quite well documented on www.uk-mkivs.net

'It's on the n/s chassis leg ' what should i actually do with it??? check if its worn or needs replacing?? cheers. scott

you can actually hear something clicking on and off somewhere down in the depths of the N/S chassis leg that corrisponds to the fans pulsing on and off so it sounds a fair diagnosis
