If you want to be really sure, call 0800 711811 for VW Head Office, they will be happy to help. As a VW Service Advisor, I can say yes, you pay more at a VW Dealership for servicing, but if something goes wrong, or you have any cause for complaint, your Main Dealer will go a lot further to help. Having VW Specialist Technicians working on your vehicle also has obvious advantages. If it were me, I'd pay the extra, but its worth shopping around Main Dealers in the area, you may get a pricematch. :-)
