2013 AUDI ALLROAD Electrical System Problems

A CHECK ENGINE LIGHT AND "DTC" LIGHT CAME ON THE DASH WHILE DRIVING, BUT THE CAR HAD NO SYMPTOMS OF FAULT OTHERWISE. DURING ONE FOLLOWING DAY, I WAS IN THE GARAGE WHERE THE CAR WAS PARKED, WAS NOT RUNNING AND UNLOCKED WITH KEYS INSIDE, AND SMELLED AN ELECTRICAL FIRE. I OPENED THE HOOD AND FOUND A SOFTBALL SIZED FIRE BURNING FROM AN ELECTRICAL CONNECTOR COMING FROM THE SIDE OF THE ENGINE. AFTER PUTTING THE FIRE OUT, I FOUND A BLOWN 'ENGINE MANAGEMENT' FUSE WHICH MAY BE ORIGINALLY TRIGGERED THE DASHBOARD FAULTS. I COULD NOT DISCONNECT THE CONNECTOR BECAUSE IT HAS MELTED TOGETHER, BUT AM HOPING THE BLOWN FUSE WAS FOR THAT CIRCUIT SO NO ELECTRICITY IS FLOWING THROUGH.
