There has been so much written about carbon build up not being covered under CPO warranty and it being a "maintenance" issue. But some have had luck getting the dealer/BMWNA to pay for it. Is SI B11 04 12 (EGR Valve) a separate issue from carbon buildup?

I just came across a thread at BMWCCA referencing the new SI B11 03 14 (walnut shell blasting). Can anyone here confirm it? Is there a PDF floating around? Should we add it to the sticky? See below for source.
