That's unfortunate. If the x man used pumps have been problematic, I guess I'd be looking for either a new unit or a Bosch factory reman. unit. And sell the x man replacement pump. I can see how junkyard pumps might not be the best.

The xman pumps are supposed to be a remand pump. They claim in their description that they have the “highest” quality pumps.

They're probably refurbished, not actually reman'd. Most likely not reworked by Bosch. Generally when the CP3 pumps fail they just generate low pressure, not shed lots of metal like the CP4 pumps. Did your factory CP4 pump fail?

Need opinions, I haven’t spent much time here but hope I can get some good feedback. So I cp3 swapped my car about 3-4 weeks ago when doing the timing belt and I was unfortunately one of the lucky ones to get an xman pump that grenaded itself after 800 miles. Now I don’t know what to do…. All I have done so far is pulled the fuel filter and it was full of metal shavings. The car is stock and a daily driver. I was just trying to make it last, which is why I swapped it.
I bought my kit from whitbread and he immediately contacted xman and although I had zero correspondence with xman, a replacement pump showed up at my house a few days later. It’s no secret there’s been more than a few junk pumps from xman in the last couple months. I found it odd they didn’t ask for Any proof. I asked Matt from whitbread to see if xman was going to offer any compensation for my now destroyed fuel system but he didn’t ask them and they’ve had no contact with me so besides Matt offering a set of used injectors I guess I’m beat.
So I don’t know what to do. I’m kinda scared to spend $2k to replace the fuel system and put the replacement cp3 on and hope it doesn’t happen again…or spend $2500 and go back to a cp4 and forget this whole thing even happened. What would you do?
Call him on Facebook, that's what I had to do. The cp3 shouldn't push metal into the rail.

Damn, that's an attractive price on those x man kits. Not so great if a lot of the pumps are defective, I suppose. Looks like he advertises them as reconditioned, not reman'd. I wonder if someone is getting careless with sealing things up before sandblasting them.

I ordered through whitbread and xman was the pump supplier. He said he uses 3 suppliers depending on availability. United diesel is one of the others and I believe I saw someone that got a pump from them and it had a Bosch reman tag on it.

Correct fuel meter valve is 928 400 643

Cp3 would be
0445010042
Citroen / Peugeot 1.4
Also known as 1920EC

adapter plate can be obtained by Matt whitbread aka whitbread performance.
Xman now sells the adapter kit without CP3 pump. Anyone can get the adapter kit from whitbread or Xman and find a CP3 pump in Ebay or anywhere else.

Yep same kit as Stevenson kit. I wish he made his OWN kit. Stevenson seems to have removed cp3 kit off his website recently.

Oh yeah... just searched and yes i see he removed the CP3 kit.
They all have been having distributer problems. He had better luck with used, he switched to referb units and has been having issues. They have been misasembling them. If you pull yours apart. Video the whole thing.

Flush and filter the fuel system the best that I could, maybe even drop the tank for a cleaning. If you have any inclination to send the injectors out for cleaning I hear S&S can do it. Then run the new cp3.

good tip! I had my 2micron CP3 pump disassembled few years back from sitting for 2 years from other owner who put only 20k miles on it then sold the car to buyback and he kept the kit until he sold it to me via Facebook in VW TDI group (it was a gamble). it was gummed up as in hard to turn the crank so my friend took it apart and cleaned it up and assembled it then I could easily turn it with my hand without pulley so we installed it on my car, fired up like new. now its about 120k miles on it since installed.

if I were you guys, look it up on Ebay. I bought one from "nerings" seller when 2micron shuttered his business in 2015 and he helped me with this process. they are selling this,


there are few other sellers in the Europe as well. the pricing are far better than my time. (it was $400's)

Nice! That one fits the CJAA? Will add it to the watch list.

yes the pump ITSELF will fit as long as you get the adapter kit from xman or whitbread performance. I personally would go with whitbread due to pricing and much closer being in Michigan as Xman is in UK.

https://whitbreadperformance.com/collections/tdi/products/cr-tdi-cp3-adapter-kit for $319 dollars

Not without the adapter plate it won't. And if your keeping EGR. Get the pre bent line. It's a pita to get that ss high pressure line bent so it fits and uses all the anti vibe mounts.
Yeah i know about the kit thanks. No worries my CJAA is Malone stage 2 (swirl flap, EGR & DPF deleted). A friend gave me an upgraded metering valve for the CP4 and the car feels better, feels more awake and no tuning needed. This friday will install the Xman CR170 Hybrid with a 4 bar map sensor. Later will add meth and will do the CP3 some day.

Sorry, I'm a little late to the party on this discussion!
I just had a Malone stage 2/Rawtek combo installed.
Also, I just did the timing belt/water pump maintenance done at 110,000 miles.
Should I think about upgrading this HPFP on this car?
nervously,

Yes, I'm keeping it for the long term. But I've read somewhere that the CP3 gets terrible MPG and I kind of like getting 50 MPG HWY.
Also, by 2014, the stock CP4 hasn't the reputation of grenading like earlier MK6 TDIs.

Cp3 will have terrible MPG’s if wrong fuel meter valve is in it. I had that happen twice. The behaviors was:

overfueling. Piss poor MPG, limp mode, poor performance. Choppy acceleration at WOT.

That's always the risk though. Is 1300 for a cp3 kit worth a 5k fuel system? Not as many miles on the 14s as the earlier ones...

Now you have made me nervous.
Ok, how do I get the right fuel meter valve if I install the CP3?
Are we talking about part numbers here or what?

My CP3 pump was a brand new Bosch unit with the correct metering valve and my fuel mileage was totally unaffected. I don't think anyone who got their pumps from Andrew had problems like seem to be popping up sporadically lately.

Okay, again, sorry for asking obvious: a new Bosch HPFP CP3 includes the correct metering valve?
I can still get the same MPG as long as I don't drove with a heavy right foot?

Yeah same mileage. Even a bit better if you tune it. But with correct metering valve, no tuning nessisary.

what DivineChaos said is spot on! just get correct FMV with CP3, you are golden.

the stock fuel meter valve for the cp4 is 928 400 706

Common wrong fuel meter valve is 928 400 493, or any other numbers that would be too big or too small!

Notes of wrong fuel meter valve was the symptoms I had was overfueling. Piss poor MPG, limp mode, poor performance. Choppy acceleration at WOT.

Correct valve is 928 400 643 which I now have in my current 2014 JSW. silky smooth and excellent fuel economy and such.
