Fuses in an Audi A3

Hello everyone in advance, thank

my consultation, it is about an Audi A3 to which I stay if I battery in the past days
when a new one stops the radius CD
and the windshield clean

fuse of 30 amp cast and

when it is burned it burns
we pass through the workshop and dialogue fault in the apmlifier The other fuses are correct thanks

If the fuse burns it is because there is a short circuit somewhere, of the wiring that corresponds to this fuse, check in the manual part and see if the Audi is if you give me the complete data of your vehicle I can see if the autodata has the information to give you.
