Just bought a 2010 TDI Sportwagen with navigation. My questions are: (1) is it possible to convert the standard headlights to headlights with an auto on-off feature? and (2) is it possible to add rain-sensing wipers? Of the two, I would really like to add auto on-off headlights (the wiper modificaiton would be nice but is not essential). Are there commercially available kits for these operations? Is there a modification shop anywhere that you know of that does such modifications? Thanks.
