I have no idea what happened in Ricatic's case. But we are hearing only one side of the issue. I'm not saying that he is wrong but that we just don't know. I followed it as it was posted here. But I have not heard many others saying they had the same problem. There was a period when some people reported problems but since then I don't recall hearing any. Maybe Ford started dealing better with the issue.

Like most others here I haven't had any major problems, the truck just went over 50K about half of that was towing our 5ver.

I have researched the Bosch CP4.2 debacle in every truck, SUV and sedan that it is installed in in the USA here. You can do a search on NHTSA 11003 EA for Engineering Analysis. I've pretty much read everything every manufacturer that uses this HPFP has had to provide, except the redacted portions of communications. The Bosch HPFP has a design defect, IMHO. Don't rev the motor hard or high, you'll float the pistons and rollers in that HPFP, and the following roller will float and lose alignment with the cam, and then your problems start and end with failure. IMHO, it is a defective design. Bosch's claim of self aligning is pure BS, it's such a problem that VW did a hush hush and had Delphi redesign the HPFP in a smaller verson with a rectangular following foot for the piston bore, versus a round one, that is problematic with the Bosch design.

The Delphi system

The standard line from Ford, or VW, or Audi, or Porsche is that "Your fuel is contaminated". Of course it's contaminated, ask them to specify what it is contaminated with, and that you demand that they show you the contamination that CAUSED the failure, not contamination as a RESULT of the failure. It's contaminated with bits of metal from a Bosch HPFP that ate itself alive while failing. Metal Swarf, like the pump is a machine shop cutting metal. All Bosch material that contaminated your whole complete fuel system, with no way of getting it all out and recontaminating your new HPFP again, unless you replace everything that metal swarf loaded contaminated diesel fuel touched.






VW, AUDI, and Ford have used the deny, deny, deny tactic, to pad their bottom line. Do yourself a favor, pay the core charge to keep that HPFP and take it you your attorney if you feel like suing, you'll need it as evidence. Might have to pay for some time of a Failure Analysis Engineer to testify, but you'll hand Ford their walking papers and set a precedent for future losses when they deny it. Also, file a Complaint with NHTSA if you ever lose a HPFP on you 2011 or later ford 6.7 diesel, and reference EA11003, to be added to the Bosch pump list of failures.
