Tired of your troublesome CP4? Let's fix it! This CP3 adapter kit fits the 09-14 CBEA/CJAA/CKRA family of TDI's using a Bosch 0445010194 CP3 pump from a 09-12 BMW 335D or X5D. An ECU tune update is strongly recommended for optimal rail pressure control with no fault codes, please see the last two product pictures of datalogs showing the difference before and after a tune update.
All parts are CNC machined in house. The adapter plate is machined from 7075-T6 aluminum and the hub is machined from 1215 steel.
The kit includes the pump adapter plate, pulley hub, high pressure fuel outlet adapter fitting, banjo fuel fittings, and all necessary nuts and bolts for install. For the CKRA Passat, the CNC machined/ TIG welded coolant neck is needed as the factory neck will hit the CP3.
The OEM high pressure fuel line requires minor re-bending to work with this kit. A good quality 1/4" or 6mm tube bender is suggested such as this one.
This is available as a kit only if you would like to source your own pump, or with a brand new Bosch pump that will ship with the kit directly from WPI.

If you refuse to read instructions, please note that YOU MUST TRANSFER OVER THE SPRING FROM THE OEM HIGH PRESSURE OUTLET FITTING TO THE NEW OUTLET FITTING. If you don't do this your pump will be junk in a mile. If you didn't already know this, you should probably read the instructions....
