Tell me about it, the amount of times i've blown MAP sensor lines, fuel pressure regulator lines, wastegate lines...well you get the picture. I have lost count.
The fact is in most cases the problem is the simplest of all the choices. I have spent hours trying to fix things not understanding why they wouldn't work and then find simply a loose earth or a disconnected plug or something similar.
When people (and funnily enough it always seems to be mechanics.....go figure) start going on wild goose chases blaming this and that it is always the simplest thing never the most complicated.
That's what I have found anyway.
Glad you sorted it.
