BMW now offers updated fuel injectors

I am aware this is the incorrect forum (F07 has very little action) but I felt this was relevant to F10 crowd. I purchased my 550I GT used 4 months ago (BMW CPO). It has been in the shop 3 times now. 1 oil pump replaced, and 2 times for drive train malfunction error. BMW dealer is now replacing my battery and all 8 fuel injectors. The service manager informed me BMW now has updated fuel injectors for these engines. Instead of just replacing 1 they are now doing all 8. Just a heads up. I have read plenty of complaints about the injectors on this board. I hope this information helps.

Thanks. I took mine in last Friday and picked it up today. They replaced all 8 injectors as well and full charged the battery. Not sure what the battery has to do with the injectors.
