Yup, you should put +FM back in the diff. There IS a reason why BMW says never to switch back once you start to use +FM in a diff.
@dEvo6 Sorry to hear they used the wrong oil. Just look at the guys who bought the new M3/M4... they are going thru these "hassles" too. I don't understand why BMW does not properly train their dealer network.
