I would say through the range of T31 with 2.0l 6 speed manual box they used the same diff .Not sure about the auto gearbox diff in the T31 though .Don't forget the 2.0l diesel manual 6 speed quashqai had same running gear as the T31 so same diiff too .Ring a few breakers yards .Don;t be worried about buying from a breakers yard . I fitted a rear subframe with the diff last year from a 2009 year and is absolutely fine(Get the breakers to drop a bit of oil out the diff if worried)
