It is the CP4.. there is an aftermarket replacement for the CP4, but it is not the cp3.Does it have a cp4 pump or a cp3 pump?
The cp4 pump on my cousins Jetta died a few weeks ago, and the parts to convert it to a cp3 were the same price as a new cp4 so he's gonna have a cp3 pump Jetta TDI.
Yes, I have read many stories of the CP4 failures and a $12k USD repair. I have also read many stories of trucks with 300k miles with no CP4 issues.
My plan is to continue to be proactive in fuel filter and water seperater replacement. Use fuel lube and purchase diesel at high volume station.
No guarantees in life, but hoping the above steps and the warranty reduce some of the risks.
