MullenaxM,
I have an 08 2500 6.7 completely stock motor, I have an AFE drop-in filter and a boost/egt gage. I just started noticing turbo surges, power and mileage losses and issues with the engine brake. Yesterday i took my truck into a local dealer and they told me I had the following codes:
P226B (and I WAS seeing boost #s of up to 34/35)
P2262
B1629
B169C
since day one I have NEVER seen a message about the DPF, or regen or any other message on my overhead or from my odometer as I have read about in my owners manual or read about here.
Im not too impressed with either of the local dealers they did not explain anything to me other than to tell me that 'parts were on order' and "I think they just need to wash the turbo or they need a special tool to do that and they have to order it' What I can gather from reading about 2262 and 226b is that Im in for a new turbo and maybe a new dpf?
Thanks, Semper Fi!
