I got 50ml centrifuge sample bottles from one of the labs at work and attached one to each injector. I then tried to start the engine. It took three attempts, none of which actually started the engine. I would guess by ear, that the engine was cranking in the region of 90-100 rpm.

Numbering the cylinders 1 - 4 from the front of the engine, left hand side and 5 - 8 from the front right hand side I got: 1 - 0ml, 2 - 10ml, 3 - 0ml, 4 - 0ml, 5 - 20ml, 6 - 13ml, and 7 and 8 were both 0ml.

So I'm assuming that this means that injectors for number 2, 5 and 6 are knackered and are the cause of my staring issue, combined with the slow cranking as well probably.

Can the injectors be repaired to reduce the spills?

Do the injectors require special tools/procedures that would make it very difficult to do the job?

I know the 2.0 TDi is supposed to need special tools but there are plenty of articles of people doing them without. at least there seems to be a light, albeit very distant, at the end of the tunnel!
After a leak off test, if you feel that a couple of the injectors are excessive and could be sticking then they can be sent away and tested by specialist and exchanged for recons if faulty.
