I've had issues with the local dealer for a while. On a recent trip back from New York City, we were running very low on AdBlue, it flashed 200 miles yet service wasn't for another 1000. So on the way out, we stopped at a Volkswagen of America and told them the situation and that I didn't want to run out before making it home, about 400 miles, so they brought out two big jugs, we had to unload the back of the Touareg (what a pain) took out the spare and they filled it up, and splashed it around making little white crystal stains in the back of the vehicle. Ugh. It was full to the top of the fill tube. They charged me $20 cash and I was on my way. I took it to the local dealer a couple weeks after for a scheduled service and told them about the trip and getting it filled, he must have forgotten because on my bill was $34 for AdBlue. I asked him about it, after telling him 1 hour prior it was just filled, and he said, oh yeah, it was just about empty, that's normal though, it goes right along with the service interval. I almost lost my mind. Haven't been back to them since. And they refused to adjust the bill.
