Today were installing the Whitbread CP4 Metering control valve bypass kit or also known as the CP4 Disaster prevention kit. Along with the bypass kit were installing 2 CAT 1R-0750 filters which filter down to 2 microns which should help keep the fuel clean. Parts list at the bottom.
-This is an alternative to the once popular 2Micron PureFlow and ContainFlow kits that are no longer available new.
-As these "DieselGate" TDI's leave warranty the CP4 can be a concern to some people because of the expensive repair cost of replacing the entire fuel system. The CP3 is an available swap but can be costly, this is a cheaper option to contain the failure to the pump only.
