    CP3 fuel pump upgrade thread

    Why on earth would anyone pay approximately $950.00 (tax and shipping) for a CP3 conversion kit + a remanufactured CP3 from WB that looks like a prototype and based on pumps available primarily in Europe that requires cutting a connecter and and grinding a part to get it to work when you can get...

    CP3 fuel pump upgrade thread

    That's not true. FCP Euro does not request information on the application when warrantying a part they sold that fails. If the part fails, they replace it. Period. https://www.fcpeuro.com/page/lifetime-guarantee

    CP3 fuel pump upgrade thread

    Hello. You could use the part number for the CP3 pump I mentioned and use it to look for the vehicles that use it. Most vendors show the vehicles a part is compatible with. I looked for used ones first. It's not worth saving $100-$200.00 for a used one with unknown miles (if you happen to...

    CP3 fuel pump upgrade thread

    If you go to 2microns' website, it's clear it's no longer in business. The best person to ask whether a tune is necessary is a tuner (Malone Tuning offers the CP3 option). That you can replace the CP4 with a CP3 and the car runs, does not mean the car is running as it should. Most any repair...

    CP3 fuel pump upgrade thread

    It's not a bad idea to read the thread, at least the posts made over the last year, before asking a question. If you do, you'll find the answers to most, if not all, of your questions regarding the CP3 conversion, and you'd also discover you could get a kit from a U.S. manufacturer that uses a...

    AC won't kick in until the engine is under load (WOT)

    This happened to my 2012 SportWagen. It was the RCV valve. There's a company that produces an upgraded one. The ones that come installed in the compressors are not of the best quality. URL:https://www.rkxtech.com/collections/air-conditioning You'll have to check the sticker on your...

    CP3 fuel pump upgrade thread

    Hello. This thread is dedicated to that topic. All the information you will need is in it. I'd opt for a kit that uses a pump that is available in the U.S. Most, if not all, of the other kits require a CP3 pump that is available in Europe only, and most are rebuilt. Also, some of the...

    CP3 fuel pump upgrade thread

    If I am not mistaken, the "grill" thingy is for cooling the built-in auxiliary pump. The BMW pump does not have once, so the VW auxiliary pump is not deleted. The auxiliary pump is deleted when using the CP3 pump sourced from Europe that is offered with the other CP3 kits. The one from Fisher...

    CP3 fuel pump upgrade thread

    You can get a kit from Fisher Motorworks that is compatible with the CKRA engine. A benefit of this kit is that it's based on a CP3 Bosch pump for BWWs, so it's easily sourced in the U.S., unlike the other CP3 kits whose pump is from Europe that are rebuilt. I picked up a band new one for...

    Euro tunning 6th gear add on kit

    You can install a MKV 02Q 6-speed in a MKIV 1.8t or 2.0L 8v. It should work on any TDI that mounts to a transmission with the O2J's bell housing. You have to use the R32 flywheel, clutch, and pressure plate from Sachs. I tried one for the R32 by a high performance shops that made clutches...

    Photos of Darkside Developments CP3 Upgrade Kit?

    Hello tjg, Thank you for the photos. I appreciate it. As for the fuel pressure sensor on the CP3 fuel pump, do I use the that's installed in the CP4 one, or do I have to order another sensor? The car is stock. This is a reliability upgrade, not a performance once, if you need to know to...

    Hello, I'm researching installing a CP3 fuel pump in my 2012 Jetta SportWagen TDI, engine code CJAA, and have found a few venders who sell them. One of them is called Darkside Developments. On the page for this kit, they do not provide photos of the installation kit. I contacted them and...

    Diagnosing Possible Fuel Pressure Issue 2012 SportWagen TDI CJAA

    Hello Shoveltrev. Yep, I see it now. One's for fastening it to the fuel rail, and the other's for orienting the plug. Do you happen to remember the size of the wrench you used to install it? The largest one I have is 23mm, and it's too small. It looks like it's 25-26mm. Thanks, and have...

    Hello Dannyboy. Thank you for the input! I'm replacing that pump as well given that it's fairly inexpensive and easy to remove and replace. Have a good day.

    Diagnosing Possible Fuel Pressure Issue 2012 SportWagen TDI CJAA

    Hello. Thanks! To replace the FPR, does the fuel rail need to be removed? Can I do it with the fuel rail installed? It looks like it would need about an 17/18mm deep socket if doing it with the rail on. Have a good day.

    Diagnosing Possible Fuel Pressure Issue 2012 SportWagen TDI CJAA

    Hello. Thank you for the quick reply and information. Yes, I thought it might be the fuel pressure regulator. I have one on order, so I hope it's that. The injectors are quite within spec according to VCDS when the engine is running, and I don't have any sort of smoke when cranking the...

    Hello. I'm trying to resolve an issue my 2012 VW Jetta SportWagen TDI (Engine Code CJAA) is experiencing. Issue: On the first start of the day, it will generally will not start. It can take multiple cranks to start. After about 3 seconds, I stop cranking. Sometimes, it almost starts, but then...
