I have had constact issues with the factory headlights in 2007 Passat 2.0 wagon. Bulbs were never bright, would constantly go out. I purchased a headlight assembly replacement for both sides from carid. The replacements are LED w/ DRL. link below
After replacing both sides the low beams will not come on and DRL's do not come on. High beams work, the led strip underneath works, and the side drl will come on when lights tuirned into on position.
This is driving me crazy. Is there a fuse replacement that needs to be made for LED's, does the computer need to be flashed to switch the current? Also the fuse for the lowbeams is supposed to be a 10 amp in spot 5 but this spot is empty on both fuse panel sides.
