Ford's answers to the NHTSA 6.7 Investigation

There was a request for a link to Ford's answer's to the NHTSA investigation posted on a previous thread, since closed. Here is the link:

Ford's NHTSA Answers to the 6.7 investigation

This PDF is over 20 pages long. There are some interesting statements contained in the documents. My favorite is the one where Ford says they buy the pump from Bosch as a "black box" and do no testing of the component. It is closely followed by the tantamount admission that the pump will not provide a long service life when exposed to the poor lubricity fuel found in the US. You will have to do the math using the sales versus failure tables for the US and Canadian trucks. Eye opening difference to say the least...

Yes we all know how great the 6.0 is, you told so.

Want to buy a super reliable 6.0 for $39,999?

I'll give you $5000 for it if you deliver it to my driveway.

Speculation:

Could regen cause a fuel pressure / electrical event that causes the pump to fail?

Is there any connection at all?

Another call for information here.

Need to know:

Was there a DPF regen event immediately prior to failure?

If yes, was there any irregularities in the previous regens?

i.e. run longer than expected, etc.


For those who don't have a 6.7 Ford, tell me about the regen cycle and how it works on yours.

i.e. on GM, it is regen via dedicated fuel injector

What is it on VW, is it extra fuel injected at exhaust stroke into Combustion chamber?

Don't know about the VW. You are correct on the GMs dedicated regen injector. I have read that it is fed via a extra port off of the CP4.

Not sure how it could make any difference, but am interested in what your thinking is on it

Don't know about the Mercedes warranty procedures and failure rates but GM's answers to these same NHTSA questions revealed that they had similar but slightly higher CP4 failure rates as Ford.

The difference...GM is taking care of their customers by fixing the failed fuel systems under warranty. Earlier in the discussion about the CP4 failures, I mentioned a "pallet full" of failed GM CP4 HPFP's sitting in Bosch's warehouse. I was told about these pumps by an unimpeachable source. The problem with convincing the GM faithful of the truth of this pallet full of pumps was there was virtually no mention of these failures anywhere. Thanks to the NHTSA investigation, we now know why there was a pile of GM pumps at Bosch...they had been returned for warranty reimbursement...Kudo's to GM for standing firmly behind the customers who paid $50,000 of their hard earned money to buy the trucks.

Auto makers tend to pay real careful attention if a consumer complains about emissions compliance and warranty coverage of this to the right agency (who bounce the complaint to the manufacture to fix).

There is some confusion under which warranties the HPFP and Injectors are covered under.

Here is the scoop:

Bumper to Bumper

Then Powertrain

THEN Emissions

Performance / Failure

Either Federal or California


The longest one by time / mileage is the emissions.


That warranty is the killer in terms of sticking manufacturers with fixing it.

A defective HPFP / Fuel Injection system mean they cannot pass emissions.

My experience is the following on a GM product. But the printed warranty always wins....
Bumper to bumper
Emissions
powertrain

EDIT - Also want the paperwork to reflect the proper warranty section and codes. Emission warranty performance is monitored by several agencies of power.

Ditto any circuit flow diagrams of how this works (I'm not a diesel
guy)

Especially EGR circuit
