I have been trying to get Volkswagen to resolve the poor headlight problems on my T6 as well. I have since tested my and other T6 vehicles and found that the voltage at the H4 halogen light bulb is only 11.1 Volts. The South Africa and European standard is 13.2 Volts. It is estimated that at 11.1 Volts the H4 bulbs only emits 55% of the 100% emitted at 13.2 Volts.
I expect that Volkswagen will have to do an international recall to get the vehicles up to standard. I would suggest that everybody have their vehicle tested and take it up with Volkswagen in your region to get this issue resolved.
