I've had my 07 6.7 in the shop 6 times now for the P2262 (2 mobile desoots, 1 new turbo, 3 turbo cleanings). This last trip, which was a final repair attempt by dodge before it's a lemon, was pitiful. All they did was 3 cans of turbo cleaner and a new ECM update. The downside, the ECM update that is supposed to control the soot problem was a MAJOR loss of power in my truck. I'm not sure if everyone is having this experience, but my truck drives awful. This seems like a bandaid for the problem because no one at chrysler seems to fully understand the problem. I know they will eventually get all these issues worked out, but it's pretty crappy that a lot of people are getting the shaft. Anybody else having any issues/stories with the P2262 code, feel free to share.
