What type of crimp terminals are these?
I think I figured it out. According to this page (German), the connectors for the narrow pins are of the TE Connectivity MCON 1.2 type. There are two variants, with Volkswagen using the locking lace (LL) type. The wider pins seem to be TE Connectivity MCP 2.8 type. 

I will order them now. I'll update this answer if they end up not fitting.
