Took my S-line Sportback into Audi as part of a 'Winter Health Check' promotion today. One of the jobs done was a software upgrade for the xenon headlights. Thought I'd mention it for all the S-line and xenon headlight option folk out there. They said it's not urgent (i.e. a recall), but they'll do the upgrade to cars as they visit the dealerships. cheers, Paul.
