Why would they plug in your car for a 10k service, its going to be some lube tech with no experience changing your oil. I work at a dealer but not VW as a master tech we dont touch oil changes under 30k miles it goes straight to the noobs as they get paid way less. If there is a problem or a recall then we get it and i dont give a shit if the exhaust it coming out your hood i wont plug the car to the scan tool unless its needed. Become friends with the writers or techs and you'll be surprised how much they can help or cover the repairs for you. I cant tell you how many times we rolled the mileage back on the repair order to help a customer out if they where just out of warranty.
