you don't have a plastic positive terminal cover on that positive post ?
it's stock equipment.
I use that, plus a thick piece of rubber on top of the battery, and dabs of
silicone to hold things where they belong sometimes too.

quite dumb of them to put a metal battery ( or screws ) cover fractions of
an inch from 600 amps of hot battery power.  You can arc weld with that
power, that's how much power is in a good starting battery.

If that ever shorts out ...... ( and example of german engineering that is
only designed to work right when it IS right  .....no margins for anything
else )
and if you don't have a battery cut off switch .....
it's gonna be a lot of fun unscrewing red hot battery cover screws.
........hoping the are not fuse-welded into place.
while you're hoping a fire doesn't start .....
or ...........if you've even seen this.........whole melted wiring
harnesses.

at least you found it now, and not some much worse time later !
