That would take a wee minute sending them to Germany though. I don't think I could wait that long. I'd rather have the satisfaction of having done it myself or do the pd nozzles require different setting up to the ve's. I know the pd have a pump for each injector but never had my hands on a real live one.
Everyone you speak to about pd nozzle swaps say that they requir a lot of setting up and balancing etc but I've never done it I swap them myself and never had a
problem there's a couple of steps I take though that maybe
help I do the swaps indoors in as clean of an invirernment as possible also I have made a little rig that clamps around the nozzle and also around the injector body so that you can unscrew the nozzle retainer without spinning the nozzle and damaging the the stuff inside also when torquing up the nozzle retainer after the swap I do all 4 to the same torque and finally fir new seals.
This seems to have worked for me so far have done 4 sets already without problems and saves you a couple 100quid depending on we're you get your nozzles of course mind u I've only fitted +50 and +80 nozzles which arnt terribly big I would say the bigger you go the more problems you would have..
Germany is quite a ways away probly a couple of weeks turnaround time and yeah whenever you get parts like these there always an urgency I have a few vehicles so I don't mind waiting a couple weeks to get my nozzles.
