Diesel L322 - Inlet manifold butterfly flaps?

Been reading a few posts on a BMW Forum (TD6 engines are BMW if im not mistaken) and a lot of the posts on there mention the inlet manifold butterfly flaps going 'bang' and destroying the engines, anyone experienced this, or heard of it on RR's?

And how would you go about getting them checked, if you can?

There's a modification available for the BMW engines (year 2000 on I think) where they remove these butterfly valves altogether and blank the holes off. I think they were a steel butterfly on a plastic spindle (or something like that), anyway, the plastic bit has a habit of breaking off and the butterfly then gets injested into the engine, buggers your bore, piston and valves and then gets spit out the other side to bugger your turbo as well. BMW modified the parts I think around 2004 or so. They were 'sympathetic' to claims outside the warranty period. I have no idea at all though if they were fitted to the Land Rover variants of the engine.
