Nice DIY. I used this as a guide, thank you. Couple of things I learned:
- For removal of the 4 screws that hold the fuse box in place (step #6), I believe the screws are actually 3mm hex and not T20 Torx (though I can't find official documentation).
- For anyone who doesn't already know this repair is now covered for free under a recall.
- There are also two "snap in" tabs on the two upper screw holes that need to be pried out of place before you can pull the fuse box towards you.
- I used the long side (123mm) with the ball end of the 3mm hex wrench pictured below to just barely reach the furthest screws with a straight shot, no extensions or adapters needed. Magnetize the end to better manage the screws as you uninstall/re-install them.
- If you choose to replace the entire cable (BMW Part# 61129269907) from the fuse box to the battery in the trunk, in my E92 coupe, the replacement cable ended up being about 6" longer than the original.
