There's been quite a few cars here that have had battery's replaced and software updated at the same time. To keep up with the warranty I doubt the dealer would install a new battery without the software update.
I'm guessing your BMW dealer is not your Dinan dealer?
Lets hope the S2 re-install doesn't impact the BMW software update for the battery.
Dinan shouldn't charge for a reinstall if your car required a BMW software update. Keep us posted on how it turns out.
