Thanks again Robby363 for your help.
If you need the smooth idler pulley number 8 in the diagram this is the part# 112 202 01 19. I had to replace mine shortly after I replaced the supercharger idler pulley. The cheapest one I could find was this one on ebay. http://www.ebay.com/itm/NEW-Mercedes-SLK32-W203-C32-AMG-Drive-Belt-Idler-Pulley-GENUINE-112-202-01-19-/231162527114?pt=Motors_Car_Truck_Parts_Accessories&hash=item35d25c3d8a&vxp=mtr
