It's amazing how you can gleen so much information from one DTC(P0402). It's usually P0401 on these Fords. How extensive would the repair bill have been if he had the more common P0401. I'll bet the intake would have to come off. How does this happen at your local dealership? Is this a conspiracy? Does the owner tell the manager to generate revenue who tells the service writer to order unneeded repairs who tells the mechanic to do them and he completes the work order knowing most of the repairs aren't needed other than the power steering fluid flush(I'm a big fan of changing fluids to avoid having to change parts down the road) and maybe the DPFE? Ford has made millions on the out of warranty EGR codes. Imagine how different the work order would have looked had this vehichle still been in warranty? At least this owner had the good sense to ask if this was a scam, but what about the poor little old lady with blue hair. She probably doesn't even know about this site or how to get to it.
