Well, the honeymoon is over ... after an awesome 12k miles, a check engine light came on last Tuesday morning. I had just bought a Scangauge II so I tried to check the codes and clear them, but I'm not sure the codes it gave me were right. The light cleared and stayed off while at idle (did not drive it anywhere) and I intended to get it checked after I returned from a trip that week, but then in an unrelated incident later that day I had to get the car towed to the dealer to get the fuel tank drained/flushed (another story for another day, but, don't let your brain shut off and go into autopilot when you are adding DEF!). I mentioned the CEL from earlier and asked that they check that out once the tank was flushed. Well, Saturday they told me the CEL is because I need a new turbocharger (?!?!?!). Codes they got are P049D and P003A. They said there is a defect where the vanes aren't opening or something along those lines and the only solution is to replace the whole turbo. Which they don't have so I have to wait. I do have a loaner car and it is all covered under warranty which I'm grateful for, but this really stinks. I haven't found any similar issues in searches so I don't understand what went wrong. The service managers insist it wouldn't be related to anything I did or didn't do, or driving style, and is just a manufacturing defect but naturally I am worried there is some reason, or this is going to be a recurring issue. I'm not great with electronics or computers, so I don't really understand what's wrong, which frustrates me ... I'm the kind of person who wants to know every detail even when I'm not paying for the work. Hopefully the car will be done this week and I will report back. I'm worried it won't be the same or it's all going to be downhill from here. I think it makes it worse that this is a unicorn car and I can't get another one, or anything like it. I really love it so I hope this is just a setback and it will be back to its 70-mpg self soon.
