Brilliant post CG - I was looking for that exact technical document this week.
I am slightly concerned having studied it that they mention that the i4 uses a Mitsubishi turbocharger, but does not specifically name which one. The one thing that I sincerely do hope is that it's not the TD04V variant, as used on the old SD4 engine - whilst usually ultra-reliable, they have a known Achilles heel when they were used on Freelanders, in that the actuators are solid state, and the electronics are prone to frying, thus causing the actuator arm to seize. Annoyingly, replacing this part is not possible, as its not available and the entire turbocharger will need replacing, at considerable expense (as I well know!)
If anyone on here is able to identify which Mitsi turbo is actually used on the i4 engine, that would be most helpful.
