Have read that I'd need a new windscreen, but the diy guide for the Golf says I dont. How different is the auto light/wiper system between our cars? http://forums.vwvortex.com/zerothread?id=2626178&page=1 The link on that site doesnt really work for me, alternative below. http://www.dubdiy.net/mkvaudio/images/VWJettaRainLightSensorInstall.pdf Does anyone have the part number required for the Audi? A guide would be champ as well, but I've googled long and hard to no avail Used to think "meh..I can switch on the lights and wiper myself..no need to waste money on these techno wizardy", but after driving mom's tiguan with autoeverything, my S3 suddently feels "cheap" without these fancy gadgets.
