After my experience today with new parts for the f30,I would be even more incredulous.
BMWUSA has a light if not nonexistent grip on what fits the f30s, what part numbers are correct, and what things cost.
I will ask my dealer to ask the local rep about this for those that already purchased the grill and exhaust for a retroactive program...
