Hello guys,
so I am retrofitting SA508 (front and rear PDC) to my 2011 E90 335i xDrive, since it did not come with it from factory as many US models don't come with it somehow.

Anyway, when I unscrewed the fuse box assembly I removed all the fuses to check for any blown ones. All of the fuses looked like the one on the picture above more or less (heat discoloration).

My question is: is this okay or does it indicate that there is moisture ingress or too much current flowing to the fuses?

I replaced the windshield last summer and when I did it, I did not put the weather trim back on which guides the flowing water down to the drain holes at the a pillars. This might also explain why the footwell trim was discolored/moldy.

Thank you all for any help!
