I need to insert new fuse terminal and do not know how does it look like.
Maybe somebody have one and can take a picture? It would be perfect picture with a ruller to see size.
What exactly are you wanting to do? Change a fuse that is there for a replacement? Fit a fuse where there is already the connections in the fuse box? Add a new fuse altogether that has no connections already in the fuse box? If the latter then you will need to run wiring for the circuit you wish to add.
If the fuse box is damaged or melted it can be easier just replacing the whole unit.
One fuse was melted so i just added bigger terminals (which found in the garage) and fuse outside the fuse box. So now i want to add right therminals to their place in emty slot.
Here's a link to a site listing the part numbers for the repair wires to add additional circuits to a VW Golf fusebox, hopefully these will be the same for the A2:
Worth checking with the parts guys on the forum as a complete fuse box could be a good buy, just for the connectors and wire 'tails' (assuming the harness is just chopped off with a reasonable length of wire left on the connectors)
