I ended up just going with an oil change (minus the DEF and other stuff - like replacing air cabin filter for 250 dollars that I can do for 20 with amazon). Cost was 135 with a car wash. Also had the dealer look into other issues. I will now have to go over the VW to get the DEF bottle on the cheap. Thanks for all of the suggestions.
