I ran b100 home brew for 150K in my 2004 Golf TDi with no problem. This was the "Pumpe Duse" engine and if i am not mistaken the fuel pressures are similar to the Common rail system. I don't know if this is comparable but it seems that in this case pressure is pressure no matter how its delivered to the injector.
