Hi. Now another code has popped up.
17956 Boost Pressure Control Valve Open.
Sounds like it shouldn't be.
Is this my Split r dump valve messing this up? Only been on a week?
Any help would be invaluable.

Hi again mate.

It should say "open circuit" http://wiki.ross-tech.com/wiki/index.php/17956/P1548/005448

So either the N75's not plugged in, the wiring is broken, or the valve itself is faulty.



Cheers.
I did unplug what ever electrical connector is directly to the right of the dump valve to make it easier to fit it.
Then drove off forgetting to put it back in.
Drove like **** and pulled in looked and saw it was unplugged.
Plugged in car fine.
Might that be the case or is that nothing to do with it?

Yes that's exactly the case mate, that's the N75 (or boost control valve). Delete the code and forget it, the quick drive with it unplugged would of triggered it. If it's plugged back in then there's n nothing to worry about.
