I am having the same problem with headlights, both low beams and one high beam.

May be way off base here but have all the fuses been tested with headlights on? V/W famous for having a dedicated fuse for 'each' light! ... Just saying...

Any reputable shop/technician can do an electrical trace and repair (probably 200.00 to 275.00) depending on how hard it is to find , assuming there is a broken wire (doubtful-unless collision damage) as all the lights are powered by different wires.
