On my way to Le Mans last week the car lost power going up a hill, it did the same when trying to over take someone.
Foot down and no power.
Limped it to the camp site and took a look at the engine.
Unable to see any split pipes, any thing broken or hanging off.
3 days later I limped it back to the UK.
Its now at the garage getting some other things fixed before the turbo is looked.
Things I've checked.
Cables, pipes and plugs. All ok.
Tested with out MAF, N75 and no change.
Removed cold feed pipe to turbo and had a wiggle of the turbo, no movement up/down or left/right.
No smoke or noise from the trubo, I normally get a slight whistle (no idea what that means).
Tried moving the actuator arm but it never moved.
Is it meant to move up/down freely or be hard to move?
Checked the error logs and there was something about the manifold pressure but it never came back after I cleared the faults (I left the code at home).
If any one has any ideas or thoughts please share.
When the belts and pullies have been sorted out I will look at the trubo a bit more.
I'm siding with stuck VNT vains the moment.
