Still no confirmed information but it seems clear that this is not a quick like for like exchange of the master cylinder, there is other development work still ongoing.
Because the new master cylinder is not a "like for like" substitution and may be from a different supplier the new part has to go through a re-homologation process so not to compromise the vehicles type approval. I'm told there are cylinders on test rigs in the factory going through test cycles 24/7. It is, I'm told, due to be finished this week. Quite why this is needed when an owner can choose to change a master cylinder without reference to anyone, but the manufacturer cannot, beats me.
Peter, regarding your last point; I’m guessing it is because the parts will be supplied by MMC?
