There's always the option of using the official manuals on Erwin - Geführte Suche < Volkswagen AG erWin Online - about £25 per day, plus you can print them. There are a few free online services, just search for "workshop manual" but I find them hard to use and search, they're mainly there to show you adverts.
I've seen downloads available for around a fiver on eBay too.
