Good quality parts from around the world - Belt - USA; water pump-Italy; roller Japan; Spanner Germany. I replaced it myself as VW charged me $1300. Thanks Youtube for good videos. Booo to VW for not moving the radiators 2 inches forward (where there is plenty of room in front of the bumper) to make this job 5 times easier. Allow 6-10mm clearance on the tensioner - it can be difficult to adjust. Took me about 6 hours from start to finish.
