Problem Audi A3 8P fuse blown



I have a problem with an A3 Facelift in the family. If it helps, it's an 8P from 2012, 1.6 TDI.

The problem manifests itself in the following way. A month or two ago, when I started the car, a bunch of errors appeared on my dashboard, all related to the lights, as if they were defective. Low beam, high beam, registration lights, etc. When I opened the engine fuse box, I noticed that the top left 30A fuse was blown. I changed it then and yesterday it did the same, with the same melted fuse. Any idea what it could be and how to fix it?

Thank you in advance!
