Magaizeris, I recently bought my first Audi. A 2013 A4. I'm trying to learn all I can about the vehicles and I wish I could be of more help. According to what I could find, that fuse is for the "diagnosis interface for data bus (gateway)". You might try the Ross Tech website and do a search for "Gateway fuse excessive battery drain, Audi A4". HTH.
