Are the dealers doing this software update at a customer's request?
I am looking for my SA to do this update by BMW but his response was that there needs to be an issue that would require an update, and since my car running is ok, my car does not need a software update.
Any input as to how you went about to have the dealer do the update will be greatly appreciated.
