Currently I have a Golf GTI Edition 30 - which as standard has the Light /Rain sensor. I really like the auto lights, but I think the wipers are terrible as they either go on too much or not enough! I was thinking about speccing this option if I do a factory order - but as my dealer is saying August / Sept for a factory build I'm becoming tempted to take a showroom car or perhaps a 1 year old one (although I really want the new DLR headlamps!). Is it possible to fit the light sensor as a retrofit? Also - I never ordered folding mirrors on my Golf as the VW ones barely move. Are the Audi ones any better? Do they fold back 90 degrees to near flat, or do they hardly move like the Golf?
