The right headlamp went out in my 2009 S6. The local VW dealer replaced it with Audi P/N N-104-457-01 for $288. This appears to be the correct P/N according to AudiPartsUSA.com described as HID Bulb Right, S6 W/ Directional Beam 2009-2011.
However, now the right headlight DOES NOT look like the same color light as the left headlight. When the headlights are on, the left light is more clear with some blue while the new right light looks duller with no hint of blue.
Did they use the wrong part? Should they have used N-107-218-05 - HID Bulb Right, S6 W/OUT Directional Beam? What is the difference? Any suggestions on how to get them to match up both bulbs so they are identical?
