I too have recently had the cooks ferry mod completed on my 2011 330d,
however i didnt get pat @ cooks ferry to check their mod had worked as such, just took his word for it.
now im a little nervous incase something isnt right and the dealer voids my warranty.
from your experience did you just come clean, tell them about the mod, and keep your fingers crossed? notice yours is a 2010 so still in warranty.
