Found the problem guys, after letting the car cool down for a couple hours. I'e rechecked the coolant level and it turns out it's extremely low its down to a hole in the bottom of my radiator caused by my intercooler pipe rubbing on it, I've got my WEPR radiator here so that will get fitted once my new brackets arrive from TD. Thanks for all the comments and suggestions! StuDoc I completely understood where you was coming from, all the VW's I work on daily have the same problem with water pumps, thanks again for your help much appreciated!
