Hi I'm interested in purchasing a cruise control stalk for my 2002 A6 1.9TDi Avant. I found one at VAGparts.com "8L0 Cruise stalk " but there are no instructions, etc Anyone out there purchased one of these and fitted it? Does the kit come with everything I need? How easy is it to fit? Is there an idiots guide on how to install etc.... Any help appreciated. Cheers.
