Watching people ramble on about Volkswagen dealer service departments when they clearly know very little about how they operate is also quite entertaining. I know, as I worked there. And I earn a respectable living outside of them unscrewing the cars they constantly are messing up. I kept track one year, and I was nearly to 20 hacked timing belt jobs by Volkswagen dealers alone by the end of December.
Don't compare Volkswagen dealers to GM dealers in this regard. Because there is a clear track of poor service many times over from Volkswagen. I've never run across any other brand as bad in my 20+ years in the auto service industry. Not even close.
If I had a Lexus, I would gladly have no problem dropping it off at the Lexus dealer I worked at and know that the car would be taken care of. Same for Mercedes-Benz. But the Volkswagen dealer I worked at would not dare lay a wrench on my cars. I'd break out in hives at the thought of it. The Audi dealers seem to have a better level of professionalism, at least around here.
And at any of the brands I worked for, recalls were never "good" for anyone. The labor times suck, ESPECIALLY at Volkswagen. At Lexus, we could at least make our time with campaign work. At Volkswagen you'd starve. They simply don't provide ample book time pay for that type of work. Which is why shortcuts happen, and why so many campaigns get messed up. EGR cooler recalls on the BEWs are pretty much always a mess, because they can't be bothered to put that support bracket back in place, and then the pipe cracks over and over again. Until someone like me comes along, recognizes the problem lies in a missing part, and corrects it.

I am crying a little inside for all my CBEA/CJAA customers when I think of having their cars touched by some of these clowns having what HAS to be a pretty massive amount of work involving the installation of SCR. This is not like changing a part, or adding gravel guards and exhaust tip extensions. This is HUGE. My only hope is that VAG/VoA realize that in order to not make this Fail Boat take on any more water, that they must take steps to be certain that the dealers and technicians know how and are paid properly for the task at hand. I believe most of the techs are not at fault here, it is the fault of the system in which they are forced to work. And asking someone to be paid for 5 hours on a job that takes 10 isn't going to cut it.
