Hi mate, sorry about this, tried to pm you but your inbox is full! I have to remove 2 non leaking injector pipes (at the Bosch inj pump face) to get to the lower one thats leaking, is there any precautions before unscrewing the pipes? like in a common rail I know the drill but not removed any pipes from an audi tdi rotary pump jobbie, I suppose theres no pressure at all when its been off for a bit unlike the crtdi? and no doubt the injector ends will need cracked open and the engine cranked to bleed the lines before starting again? Hope its not the middle pump seal thats leaking Cheers, Scott.
