[/URL]Just to give you example below are part no for injectors used and when dropped because of issues/better manufacture etc for my A6 3.0 TDi Engine code BMK Injectors (currently mine are 059 130 277 S, must be orig.)
Thanks for the information. I am now certain you are correct and people on other forums and sellers on ebay are incorrect.
I have augmented your list of injector nozzles and then done a lot of cross-referencing to find which fuel pressure regulator they are sold with on vehicles and then looked at the pressure specification. I could not find them all, but I have posted below what I found.
As you can see, the injectors may look similar, if not identical apart from the number of ports in the nozzle being increased.
I presume as the holes are smaller they need higher pressure to atomise the fuel and give sufficient delivery.
Thanks. Looks like I need the 3x more expensive 1600 BAR units.
