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 0445010042 or 0445010031 CP3 pump. An ECU tune update is required for proper operation with no fault codes.
All parts are CNC machined in house. The kit includes the pump adapter plate, pulley hub, high pressure fuel line threaded adapter, banjo fuel fittings, and all necessary nuts and bolts for install. For the CKRA Passat, the cnc machined/welded coolant neck is needed as the factory neck hits 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.
It is available as a kit only or with a remanufactured pump with a 1 year warranty. Pumps are built to order by United Diesel in the UK and shipped directly to customers for the fastest possible delivery time. Due to a constantly thinning core supply, lead time on the pump is subject to fluctuate anywhere between 2-5 weeks. Thank you for your patience and understanding.
Until we have a free moment to make our own instructions, here is an archived copy of instructions written by 2micron from TDIClub. Please only torque the pump mounting nuts to 10-12lb-ft with anti seize on the threads.
