Exterior Lighting Related Problems of the 2010 Volkswagen Golf

Headlights problem

First sympton was a faulty warning light stating, incorrectly, that a bulb was dead. Replaced headlights under advice from dealer that the error was due to faulty voltage from a dying bulb. Condition worsened. Information center began stating that all bulbs were out each time you started the car and then finally, lights began to fail. The car lost all exterior passenger side lights and had only intermittent use of rear driver side lighting. Dealer then diagnosed problem as a melted fuse box but could not give reason for melting. No modifications have ever been made to the car. A quick interenet search revealed many people with the same problem across many Volkswagen models and that the dealer's fix of just replacing the fusebox may not address the underlying problem which may be due to a wire to the fuse box. Over $700 spent to date on repairs with no understanding of why vw fuse boxes are melting and wondering how long till my new box melts too.
