vauxhall diesel system bleeding

a video showing what I do after completing a service on a diesel vauxhall, not all cars require a computer to do this, but not all cars self prime themselves and the fuel pump relay is only active during cranking on some vehicles. this process is the same on all vauxhalls to around 2007/2009 to present, whether its a corsa, astra, insignia or like this one a cascada, not forgetting the antara and mokka (they sometimes have 2 in line filters similar to this) but same process is required.
