Have seen multiple Model S reports, both in USA and Europe, over the past few days indicating alert that battery operated pyro fuse needs replacement with newer self powered pyro fuse. In some cases pack needs removal due to location of access cover. So far underdetermined if covered under warranty.
This video (cued at 7:30 minute) shows what I believe is the current battery operated pyro fuse. Later, at the 12 minute mark, he shows updated self powered replacement utilizing a chip instead of batteries. Hopefully all replacements will have this redesigned pyro fuse not requiring periodic battery replacement.
Cannot determine exact source of attached pic of memo, but seems legit.
Looks like same issue was reported last year. Legacy Tesla Model S/X to Get Pyro Fuse End-of-Life Warnings - TeslaNorth.com
Lastly, here on TMC a few months ago. Battery Fuse Replacement 2016 Model S 90D
