Certainly sounds like a tougher job for you. Is your Passat a year 2000 generation or earlier? Though, the kit with the looms needed could just be a newish thing. 8 years the difference between our installations.
I don't live in Ireland anymore but I'd say CC is a lot more useful these days with the much longer motorway network. Having said that, the way so many idiots in Ireland sit in lane 2 or 3 of a DC/Motorway probably ruins the usefulness of CC to a large extent.
