NHTSA Update on CR HPFP failure investigation - Page 113

I have an 07 chevy duramax with a cp3 pump, in the last three years of ownership and read a couple of duramax forums I have never heard of anything like this happening on a durmax.

The Mercedes diesels, BMW diesels, Cummins diesels, 6.4 PowerStrokes, and pre-2011 Duramaxes are irrelevant.

They all use the CP3, an older pump design.

What we should be doing is:
1..Getting and looking at the internal parts of the older and different pumps.
2..Comparing the internal parts
3..Looking at the electronic fueling charts for all brands.
4..Making decisions on what to do.

What we are doing:
1..Speculating without much information
2..Makings things irrelevant instead of seeking relevant information from HPFPs that work.

I will see what I can dig up (if anything). Please everyone go on a HPFP hunt.

Bosch has been the leader in diesel fuel pumps for more than fifty (50) years where you going to turn?

According the the NHTSA report 2010 failures represent 0.11 percent. That means 99.89 percent run just fine. What more do you want??????

The same reliability,as past model VW diesel fuel systems. And IF something fails in the fuel system it doesn't cost 1/2 to 1/3 of what the car sold for new. But what do I care..................I'm "driving more and worrying less" with my new gasser.

Dweisel , did you have a hpfp fail or was it Reading some of the stories here that made you switch ?

When I started on the PD cam failure work, I was told about being an alarmist. All sorts of people quoted the low percent of failures. When the mileages got high the failures increased. Now it is common to talk of replacing PD cams.

Looking at the design and hearing of the fueling mistakes made in Europe, warns me of the possible coming failures.

I want a 2012 Passat, but right now I would not buy one. I saw some changes in the fueling system, but not what I wanted to see (I will know more when information is released by VW...maybe the information will surprise me). But Hey here I go again being an alarmist. LOL

I will be happy if I can contain a failure to $2,000 USD (and that is terrible)

I do wish I had a car with the November 2010 upgraded pump. I guess my car only has 2 of the updates. It would be nice to know what they did to improve the pump. Honestly, I wish they would just come up with something to prevent the debris from contaminating the fuel system. Then it would just be a new pump for a few hundred bucks, not really a big deal at all.

Since most truck haul all types of fuel in the same tanks it is highly possible for fuel to be contaminated when filling the trucks with fuel. Until tankers start hauling only diesel or gas or whatever there will be cross contamination.

It kills both myself and my wife to drive gassers. We've both driven diesels for over 25 years. Never had a problem with a fuel system. EVER! The 09's came out and both of us were excited about owning new tdi's. We purchased two 09's. A Sedan for my wife and a JSW for me.My wife's hpfp failed at 11,000 miles and mine failed at just over 24,000. So, until the hpfp problem is fixed......................dweisel isn't diesel anymore.

Dweisel, What is your new ride?

2011 JSW with the 2.5 gas/DGS. The wife went with the 2.5 manual Sedan. She likes it other than the hill assist. Only because that was the quickest and easiest route to make a trade. Plus VW threw in $2,000 trade assist. So that made it easier to swallow. BTW,they did not volunteer the "trade assist" and wanted to know where we heard about trade assist. We were told by a friend to ask for the trade assist.

The only real difference between the gas and diesels are: lack of torque and the mileage sucks! Other than that pretty much the same. I'd still rather be driving a diesel. Oh,well maybe some day in the distant future.

What are the odds that TWO HPFPs would fail on cars owned by the same people? What did to fuel samples show......or did they tell you? You sure gasoline was not put in the tanks by mistake? ........this just doesn't wash with me. Sorry.

I would think the odds of you ever having another failure would be slim and none. Me? I would have purchased another diesel and be done with it.
