The diff oil used should be itemised on the service schedule and the correct type is posted on one of the service threads here somewhere. If it was not the right type, yes it should be addressed ASAP but don't panic as it won't cause any damage.

The 1M has quite a stiff diff anyway and will make more of a noise when the car is cold especially at low speeds. Noisy diffs with M models are well documented on many forums and will generally quieten down over time with miles!

Although this is a road car it is very close to supercar levels of performance and the set up of this car is quite aggressive so noises from the brakes, diffs, suspension and occasional vibrations from steering rack should be expected!
