I have 2007 with the 6.7 my CEL comes on then goes off.
About a month ago light came on on the way back from work the following morning it was off, last week it did the same, now tonight it came back on so i guess I will see tomorrow morning. Anyone has an idea what is causing that? Does the CEL have to be on in order for the dealership to read the code?
Thanks,

P2262 I'd bet :woot:

it is most likely storing the code. Do the key on off on off on trick and see what code you have in there

My Dad's 07.5 does the samething...The ECM records the CEL's so even If it's not lit up when you bring it to the dealer they should be able to retrieve the CEL..

See if the December TSP was done. That 2262 code is generated by the box down with the converter and requires a flash. That box is replaced when they do the TSP. And you should have the AX flash which is March this year. That seems to have fixed quite a few problems and did improve mileage a bit.

P2262 is a turbo issue not an o2 sensor or o2 controller issue that is the G30 recall. Your also correct about the flash you need the lastest flash which is the AX.
