luminova11 Posted March 23 Share Posted March 23 I have a 2013 Q7 with xenon lamps. I'm getting it ready for the first MOT since i've had it and have noticed that the two halogen bulbs in the headlamp unit don't seem to be working. Both bulbs are good and I have no 'bulb out' warnings. What are these bulbs for? And when do they come on? Xenon is Woking properly on dip and full beam. Many thanks Quote Link to comment Share on other sites More sharing options...

Thanks Steve, I think they are probably cornering lights. I'll check later and let you know. Bryan. 1 Quote Link to comment Share on other sites More sharing options...
