Just bought my first Audi. 05, 50k and all is beautiful, but.... Lost daytime driving light on drivers side. When I went to change the bulb had disintegrated as did the 2 wires feeding it. Now I notice other wires in the unit are losing insulation too. Looks like too much heat in the housing. Anyone seen this before? Looks like I have to buy an entire H/L assy with all the guts. Not fun
