Injector with sensor question

I know the diesel injector with the sensor changed model numbers around 1999 (mine is a 1998 and falls within the VIN numbers for the older one), does anyone know if they also changed on Vauxhall Omega's with the M51 engine in too or are the ones fitted to those the same as the older ones in the Range Rover?

If its got an egr valve its the newer one if not its the older one
