Hello all, I wonder if someone could give me some info with regards to my lights on a 2006 Q7. The lights seem very dim at night and I have noticed only one set of lamps illuminated on the main headlight. On a normal car what would be the 5w sidelight isn't lit when my lights are on. If I put the daytime running lights on the lamps do illuminate in the main light but get knocked out when I put the dipped beam lights on. I have noticed the bumper lights with the indicators in them illuminate with the dipped beam but don't offer much light? I wondered if the lights built into the bumper should be my daytime running and not sidelights which they appear to be when I select sidelights on the switch unit. If this is indeed correct it may be time for a new set of Xenon lamps I guess? Help much appreciated.
