People lets not get carried away here.
The dealer is a good dealer. They have taken care of my GTi with no issues. Just because one tech goofed (and we still don't know how someone can botch something as simple as refilling AdBlue) does not mean the dealer and its service staff are terrible.
We all agree some refinement on the refill design should be done to make the design more forgiving. Either go with the Touareg or Q7 design. The brand is a good brand. The car is a good car.
As long as this is documented and if issues occur further down the road, my isolated case will be handled appropiately by the dealer (if needed by me) every step of the way.
