A4 starting problem

I am currently having problems with my A4 avant 3.0 tdi V6 Quattro. The diesel system seems to be drawing air from somewhere. I have fitted 2 NRV's in the fuel line, 1 at the tank and 1 at the engine. I have replaced all of the injection leak off pipes and also replaced the fuel filter to fuel pump pipes (in the engine bay). When i can get it to start it runs fine but when it's stopped there is air getting back into the system and it won't start again. Any ideas as to where it could be drawing air from

Hi, having the same problem so asking what was the problem? I'm guessing faulty injector or some valve which is designed to release pressure but malfunctioning...
