That's interesting. When I got the Doom Message "you have 10 starts left" while driving in Texas, searching suggested the nearest Sprinter dealer was M-B in Boerne. I drove there, arrived at 4pm with no appointment, and they were very good. Got me right in, replaced the NOx sensors and fixed the doom message.
Service manager claimed they had a couple of "really good Sprinter techs". I couldn't agree more. That was in 2019.
So what happened now -- they don't like Sprinters any more?
