This is information that comes with the recalled pump.
Yes, this is part of a card that is given to the owner of the truck AFTER the new CP4 HPFP is installed as per the outlined documents Stellantis published to the NHTSA. I suggest reading the "Technicians Service" attachment a couple pages back.
I guess they don't give that info to the rest of us since they have to replace our pumps anyway! However, if they think B20 is bad for the HPFP, they risk paying for complete fuel system replacement instead of just the pump. I think I recall that they haven't scared you away from biodiesel--no name change yet, LOL!
Well, like @biodiesel said, and other folks who know more about biodiesel than the rest of us, I gather it has more lubrication properties, however it lacks in the quality control department. Which you'd think that there would be a higher quality control on it and more attention being placed on it for future use.
Any pump sold in the USA should handle any fuel provided from the standard supply chain tanks and delivered to and sold by a licensed fuel station. Period. Full stop.
fully agree but the information dug through from the VW side show that Bosch knew from the start that this pump would have issues with the standard USLD sold in the US. It's only taken them 14 years to make it functionable. maybe
'Should" means to be hopeful that fuel sold in the U.S. will meet and exceed lubricity requirements of the CP4 pump. Then there's the real-world in which factors come into play. U.S. fuel, by definition, meets the minimum requirements of the CP4, however, borderline fuel is going to be questionable from location to location. In other words, borderline fuel means there's not much room for mistakes and miscalculations. Fuel quality is going to depend on the refinery, the wholesaler, the transporter, and the retailer. The CP3 pump is tolerant of borderline fuel whereas the CP4 pump isn't.
Personally, it should be required by law that Bosch demonstrate what they changed for the revised pump. Not only that, but demonstrate proof of testing with validated results.
I hope that some Youtuber gets one of these new Bosch CP4 pumps and does a tear down and full analysis.
A recall with no fix for 14 months and counting, imagine that!
Because of your reply i will be brave enough to start use my 2022 ED limited
So are they just installing the same pump with recommendation to use B5 fuel and use B20 sparingly and change your fuel filter every 10K or have they changed the internals of the CP4 pump? I also saw on another forum the recall pumps are CP3 pumps with an adapter so it can retro fit to the the ecodiesel engine, is this true as I see some people are getting the fuel recommendation leaflet with their recall and some are not. Mine is in line to be replaced this week, haven't heard anything from the service tech about the two questions I posed above.
It’s a new part # from Bosh so it should be a new cp4 pump variant fixing the issue. What is actually different I don’t think anyone has a definitive answer.
The EcoDiesels are getting another CP4 but it is redesigned .
Tech got back and doesn't know, just said they are replacing pump with the updated part #, he said the new pump and recall one look exactly the same, who knows if the internals are different.
You received the updated pump. Some of us live in diesel county where hundreds of EcoDiesels were sold in a concentrated area. I'm just now able to buy my 2023 Jeep Gladiator EcoDiesel which has been waiting for the recall to be completed before it could be sold. It will probably be many more months before they have a pump for my 2015 or 2020 truck. It boils down to supply and demand.
