V50 Engine D5 : D5 missfire

[Adept10]

Hi all bit desperate here anyone got a diagnostic kit in gosport area they can run on my v50 d5.
I've been replacing all the running gear on my v50 in the hope to get it on the road it's in for mot Tues next
I've got a missfire on the d5 engine sounds like a lumpy v8 I've dug out loads of gunk from egr and throttle body I also tried disconnecting the injectors one by on and all seem to be working, tried the boost vacuum which does not seem right pump is fine for solenoid is ok but applied vac direct and does not do anything to turbo ? Help!

If your EGR was badly coked up then you may need to remove the inlet manifold and clear all induction spaces especially the swirl flaps.

Lumpy running on the P1 D5 cars can be attributed to ECU water ingress...
Whip the wheel arch liner off and have a look, I capped off the air duct with gaffa tape and also drilled holes in the bottom of my ECU case so any water could drain out. If it turns out to be the ECU then you can get another one flashed by the likes of Shemtek.
