Well it's been 5 years since the T6 was released and there's no Haynes workshop manual for it ... so I guess there never will be. I found two German-language ones though, "Reparaturanleitung VW T6 Transporter" and another ""VW T6 Multivan Jetzt helfe ich mir Selbst", both easily available on eBay. But German isn't easy for me, so really I'd prefer an English-language book . Have I missed anything?
