I sound unbelievable to me, I would understand 1500miles but not 5000miles, but in fairness I am new to M cars and don't know if this is true or just a new thing.
If there is a break-in procedure, it should be documented in writing in the owners manual or elsewhere. They can't just hold you to something the dealer just said.
