ISSUE:
Some 2003-2007 F-Super Duty, 2003-2005 Excursion, and 2004-2006 E-Series vehicles or later, equipped with a 6.0L diesel engine may exhibit any one, or a combination, of the following concerns: lack of power, white/black smoke or a surge.
These concerns may or may not be accompanied by any one, or a combination, of the following diagnostic trouble codes (DTCs): P0238, P0299, P0404, P0478, P2262, and/or P2263. These concerns and/or DTCs could be a result of coking deposits inside the turbocharger. Coking deposits inside the turbocharger turbine housing can impede vane response causing high or low instances of exhaust pressure. Unexpected exhaust pressure results can cause over-boost, under-boost, insufficient or excessive exhaust gas recirculation, or unexpected EGR valve position, resulting in these symptoms.
ACTION:
Follow normal Powertrain Controls/Emissions Diagnosis (PC/ED) Manual diagnostics for the symptoms being experienced. If the PC/ED Manual diagnostics lead to turbocharger replacement, follow the Service Procedure in this TSB to check for internal turbocharger oil leaks and to determine if the turbocharger can be cleaned instead of replaced. If any step in the TSB Service Procedure leads to turbocharger replacement, replace the turbocharger and do not continue with the TSB.
Ford now wants techs to clean the turbo if its coked. International has been doing this forever. Bout damn time.
