I had a set on my 200Tdi, they were fine until the injection pump was replaced 7 because the pump rear brackets weren't refitted correctly in-line the pump gear ran out of line & pre-loaded one of the idler gear posts which sheared off after a few 100miles, got myself home & stripped the zues gears off & refitted the original timing setup with a new belt, I will not be buying another set of gears, stay with the original timing setup & just change the belt every 55,000miles, 200Tdi's seem to be very kind to their timing belts I've never had one fail in service, all the life expired belts have looked just as good when fitted, no nasty marks or wear on them.
