i havent used it yet, just saw discussion about the rail pressure sensor and thought i'd dig the specific PN out of my notes. it drives me mad darkside sells it at such a markup...

however, i will be buying that sensor before my next t-belt service. as i will be putting the CP3 in then. at 223k miles now, nearly 224k. next service at 239-240k! coming up quick....
gotcha. I got it for free (2200 bar sensor) from Darkside per store credit due to their fawk ups in the past. But yeah the mark up is nuts especially the Audi S3 intercooler…. I found several for 1/4 of their asking price on the FleaBay. (eBay in case you wondered)

I had darkside uprated intercooler, that one was a beast! But rubbing issues on the oil pan with DSG body being large, it was mainly designed with 6MT in mind.

A friend of mine came over with 6MT JSW and I would see the massive differences of 6MT to DSG which darkside intercooler would not rub. So I sold it to him.

Looks like I'm not the only one who's had issues with them... Part of my Stage 3 install took longer than expected because their S3 intercooler wouldn't fit my KermaTDI hoses despite me emailing them ahead of time asking about specific fitment. It wasn't even close either. Had to make my own hose setup, was super annoying.

Happy to report successful CP3 swap - 2013 JSW 2.0TDI, 6spd after some initial trouble.

Simultaneously did T-belt, water pump, idlers, t-stat, harmonic balancer, lower cover, full deletes + stg 2 tune. Took about 40hours to do it all, but it was my first time doing "major" work on this car though.

I will say, a third of my time was me trying to do my own DIY tune on a nickel, made it about 95% of the way. I was actually able to turn off the DPF and EGR (and tuning protection). It was drivable (drove around a few days), albeit stock power and all the DTCs were still on. While I was able to see maps themselves to attempt a stage 1 or 2 tune, I wasn't confident that it had interpreted (or "mapped the maps") correctly, in the decimal grids I was seeing erratic values instead of smooth gradients along what it thought was load/rpm/airmass.

I've done my own tuning on GM stuff with HPT and I could definitely see the parallels, but the knockoff software in this case sucked and/or seemed more geared towards euro spec cars. I found myself only able to find an approximation of my car, not the exact and usually only up to 2011. I still have my original and DPF/EGR modified binary files so I may try again in the future, and possibly document what I found so far, if there is interest. Most available info seems to be from across the pond. There is definitely a big learning curve, and admittedly, a substantial risk, in front of this knowledge, but to technically perform the read/write is a laptop + ~$160 in aliexpress hardware (which I actually had no problem with).

In the end, I wanted to get it back on the road and verify the work I did was good, so I ended up paying the big bucks, (more than the delete itself sadly), for a premade tune, which had no problem overwriting my slightly modified tune.

Just placed my order for the CP3 kit from Whitbread and getting ready to do the Timing belt change and the CR170 turbo upgrade at the same time.

Question - where are folks getting their Timing Belt Kits from? ID Parts, Diesel Geek, other options?

I did the diesel geek kit - the two small issues, maybe not exclusive to them, but I didn't feel very positive about the fit of the cam holding pin. Second was it took awhile for the CP3 to come in and by then I lost access to the instructional video.
I used pieces of a few yt videos, so maybe I had pinned it in the wrong place. I'm sure they would've re-upped if I asked, but it was already super late on a Friday when I got started so oh well, easily caught if I had checked earlier in the day.

Neither issue was a big deal, would buy again, I remember it being a better deal for the parts?

Thanks, yes I built in some lag time for the CP3 pump to arrive, looking to do the work once the weather cools down. So sometime in the October/November timeframe.

Thinking Diesel Geek for the Timing Belt Kit and the tools. ID Parts for the T-stat. And Cascade German (TuneMyEuro) for the CR170 & the Inlet Pipe required for the upgrade. Diesel Geek seems to have a higher quality kit (or at least equal) and a better price.

Yeah, it took about 2.5 months for mine to come in.
I kept the original turbo, but yeah I did the tstat from ID parts too. Hardest part was getting the alternator in and out without taking more stuff apart. It was barely possible with just the HPFP removed and EGR being deleted.

Fwiw when your talking about the kit themselves, adapter and pump, the Whitbread kit is about $500 cheaper than the fisher kit which is sold through cascade german according to their website. ($1320 vs $850) Maybe the new pump vs the remanned one is worth that cost but it seems the people with the Whitbread kit have been happy with it.

Surprise! The Whitbread CP3 pump and kit arrived yesterday (pump from England, install kit from Michigan). Remember, I ordered on 8/31. Much faster than I anticipated...
That's good to hear. Placed my order last week so we'll see. Expected it to take a couple months from what I'd been hearing.

I have received the Whitbread CP3 and Install Kit, also have the Timing belt kit. The parts bottleneck now seems to be the CR170 turbo and the required intake pipe...have been told from 10 days to several months by ID parts. ID Parts had the best price on the CR170. So, I placed my order regardless, it will arrive when it arrives.

Update 10/6/2023 - the CR170 arrived! I think I have all of the parts to begin. Let's get the party started!

So I've got a question, I have a CP3 kit from Xman however the metering valve has no part number on it... All it has is "040" on the side. I contacted Xman and their team said the part number "should" be 0928400492... Is there any way to verify this is correct? Or should I just purchase a different metering valve?

is the car inopperable as is? i thought the x man kits came with correct meters.

if you plan to have your car tuned by malone/tunezilla then keep the current meter valve and they will adjust it accordingly in the tune to the 492's. if you dont want that then get 643. no tune needed.

So I’m in the middle of the CP3 conversion and I cannot get the fuel rail line to meet the pump outlet… it’s close, the angle is right, but it’s too short/close to the block… I’m completely out of ideas. Half the time the damn tube bender just spins the line, making this even more difficult to align it exactly outside of the car

swap the pump outlet on the CP3 to one not so close to the block. you have 3 positions you can put the outlet on

like lemon curd said try a diferent outlet, i show one alternative port a page or two back, i retained my egr assembly and used my hands to bend everything, it was fairly simple in my opinion. i actually had it routed to the original outlet by making one very minor bend but it didnt allow me to get the egr back on, literally like another 3/16" was all i needed but once i switched ports i had plenty of space, all my hold down straps are in factory locations even, one is slightly tweaked but the rest lined right up. i doubt even the average vw tech who maybe hasnt seen a lot of tdi engines would even know it was swapped. a tdi guru would notice the lack of accessory pump almost immediately i hope....

I usually just use a box end of a wrench to bend the line. The stock line doesn't require too much bending if you're going to the port that is closer to the front of the car. It does help to delete the EGR valve to gain clearance for the line but isn't necessary.

I already advised all vendors to get 643's. some heard me and switched, some didn't....... I emphasized that to them that the 643's were advised by the 2micron whom I am regularly in touch with. So I adopted his advise and slapped the 643 on and viola! my old 2011 JSW ran flawlessly with the 643.

I had no idea you can could do that! After looking at the pump housing it makes perfect sense. Thank you! I ended up rerouting the rail feed line more directly instead of that 90 it does to fit around the intake. Worked great, no leaks, picked up a spare line just to be safe

Can you post a picture of your set up?

The pump has the connection at the forward most port, runs a little close to the dip stick so I added some washers on the bottom side of the ASV mount to give it space. Rail feed line runs close to the #1 glow plug plastic as well, but does not rub any hard surfaces.

So I would like some community input. After changing to the CP3 pump, many people remove the Auxiliary pump because it's not necessary. However, does retaining the Aux pump put the CP3 at any risk of failure? Is the aux pump outlet pressure too high for the metering valve or o-rings? ThatGuyTy on youtube has a fully built CJAA with an R70 CP3, he retained his Aux pump, however he has oversized injectors and runs almost 50PSI.. So is the aux pump only necessary to assist the CP3 if you need to delivery a huge amount of fuel? I don't want to go cutting fuel lines if I don't have to..

my understanding is it throws a rail pressure too high code. most cp3 pumps have a built in pump ive learned, the style found in bmw's do not however and maybe require keeping it(?) you can identify them easily based on whether or not it has the little vented thing opposing the pulley or not.

I also installed a 2200 BAR fuel rail sensor and had it tuned accordingly so the Rail target pressure is now 2000BAR rather than the stock 1900.. Perhaps the CP3 can't bypass enough fuel when combined with the stock rail pressure target and the Aux pump :unsure:
