I agree Brad.

However, all the vanes are on the turbine side, it would be near impossible to get anything in there without either putting it through the engine or pulling the turbo off. I wonder how effective the stuff would be after being burnt in the engine?

You could try pulling the exhaust I guess and spray something in there.

I've got one BV50 turbo (2.7 TDV6) that was so carboned up I couldn't physically move the vane lever even with it pulled off the car.

I've used a number of litres of 2 stroke oil on our cars attempting to stave off replacing the turbos, it has had limited success, but not enough to call it a "fix".

Yeah they are. That may be the case, but in my experience with 2 stroke at actual oil ratios (like between 25-50:1) there's potentially a tiny bit of oil in the exhaust. In the proportions recommended in a modern diesel I can't see there being anything left in the exhaust. I could well be wrong because my wife tells me I have been before (she wrote it in the calendar).
