Description
This CP3 kit allows for the replacement of the factory CP4 pump with a BMW R70 high pressure fuel pump. The CP3 pump is a more durable pump capable of running higher rail pressure. A new metering valve is not necessary to run the BMW CP3 pump, these pumps plug directly in for most customers it works with the stock tune. A small percentage of customers report high fuel rail pressure codes which necessitates a software update. This kit only works with the R70 pump.
Our pumps are sourced directly from Bosch and are brand new, NOT reman or takeoff.
Latest Revision will now fit all 2.0L North American TDI’s from 2009-2014: CBEA, CJAA, CKRA

***IMPORTANT NOTES**
-The center nut for the replacement hub should be torqued to 60nm/44 ft-lbs.
-Factory rail pressure sensor is 1875 BAR. When it fails it’s very expensive to replace, so some customers like switching to the 2200 bar sensor as it’s much more economical. It’s only required for above 200 hp builds. If your factory sensor is working correctly do not try to do this preemptively as you will likely create more problems than you will solve.
-If you have ANY debris in your fuel system it will clog the internal screen on the HPFP. Often this will blow out the plug and cause a fuel leak. Bosch has made it clear that this not an issue with the pump but rather not enough prep being done, so make sure your fuel system is completely clean to avoid buying two (or more) HPFP’s! As of this writing the only CP3 failures we have seen have been due to debris in the system. The pumps are extremely reliable and we have had 0 failures/warranty claims for actual pump defects.
-This kit does not require tuning, unless you are currently tuned. In that case you will likely need a tune update. See above for metering valve part numbers. You are still responsible to confirm the part number you receive with your kit and coordinate with your tuner.
-Some customers have chased fuel rail pressure codes. If your rail pressure code is too high it’s likely a software issue and will need a tune update. If it’s too low it’s usually mechanical in nature – injector or fuel rail.
-We will update this list with any other patterns we find. If you have any helpful hints please email them over and we will update the listing as needed. Please note one off experiences may not make the list, but as patterns emerge they will make it up here.
