No, they wouldn’t.
I’m having a tough time seeing how a dell bios update would corrupt your ME, but I guess it’s possible. If that’s it, you’ll have to follow the guide lfb6 pointed you to.
The issue with ME is that I’m not sure there’s a way to test it for corruption. I think you just have to assume it, and then clean and physically flash. I’m pretty sure it will require a physical flasher.
What I didn’t know (and still don’t know) is whether a new dell bios update would get around the “need to clean” issue, since dell bios updates will overwrite current ME data versions. I’ve had my issues, but thankfully never a corrupted ME.
