"Effects: the rear differential blades wear out very fast. Massive noises from the rear differential." Hm, could that explain the weird metallic ramble that several (including me) reported about ? That occasional, peculiar grinding/screechy rambling noise coming from the rear underside.
If it happens to be the rear diff issue (which we don't know yet), then BMW has to recall (much) more cars than the batch starting from May 12 production onwards. Mine is an early April build.

Just to add to the list: My car is a February build, and one in a while I hear a brief grinding noise from the rear. Kind of like "GRANK!"
