I've already read that post as part of my ongoing investigation .

But I think you may be onto something there gmerry. I'm very tempted to order up a new set of studs and seals. The only problem I have with this theory is that injector leaks are usually self evident from what I've heard, either making a puffing sound or giving off fumes. There is none of this that I can see/hear... but I am curious about the diesel on the injector shaft as this is above the copper compression seal and should be isolated from the nozzel... I can't find anything similar on google!

I've just sent for an EGR blanking plate as this would give identical symptoms. A couple of the EGR values look suspicious although I'm no expert So can't be sure unless somebody chips in.

Here is my Diagbox global test report, presumably this has the engine code, I think it might be 9HZ. Does anybody know why a lot of systems come up as "communication error"? Is it simply because these features are not installed?

Well after reading through and watching videos etc of how to remove the injectors and replace the seals this is the first time I have seen or heard anyone suggest changing the studs should also be part of the process but now that I have read your comments and the linked thread it makes total sense and can probably explain why leaking seals are such a problem with this engine. It's a lack of knowledge rather than a design fault. Now if you could find a fix for the cold start smoky engine and rough running for the first few minutes I may cry . Sorry for jumping on the thread just couldn't believe how something so obvious( once explained properly )is so missed. Hope it sorts your issues
