I plan on keeping my wagen for many years and I am struggling with deciding if I should replace the poorly designed CP4 pump or just run it.

The car now has 71,000 miles with no issues but I've read stories of them going without warning or obvious cause.

What have your experiences been?

I did it to my stage 3 A3 TDI (to include getting the tune adjusted to compensate for the new pump). No issues, it's great.
I'll be doing it to my stage 2 2014 sportwagen when I do an early timing belt change this december.

I put in my cp3 a couple months ago. I got it from Aurelian, he has been super helpful and the cp3 was cheap! No real change in drivability or performance now, it was in preparation of my 2060vklr that should be here in a week or two!

Would I be able to contact Aurelian for some help and to purchase a pump?

Thank you!

Yeah he is pretty active on this forum, his username is Macradiators.com. But the easiest way to message him is through messenger or his Facebook page

Did you have Malone adjust your stage 2 tune after you had the CP3 installed?

I did not, I have the slightest hesitation in 3rd gear sometime that only showed up after the swap, but they already have my stock turbo pushed pretty hard so I figured I wouldn't bother with a retune until the new turbo goes in.

Oh ok; so you already had them adjust their “cookie cutter” Stage 2 tune for a bit of extra power.

That’s interesting.. mind sharing a few details on what you had them tweak and what kind of numbers you estimate you’re producing compared to their claimed regular Stage 2 tune?

Not yet... When I do install the CP3 on my stage 2, I'll do some data logging and send the files to Malone to make any necessary tweaks.

I did it for my stage 3 and it was super easy and straightforward

I went stage 2 before I deleted, so when I had them retune for the deletes we turned it up as much as they say is still safe. I am not sure exactly what was tweaked. The numbers are probably just a couple percent more than the standard stage 2. I dont know if I would recommend it though as I am hitting my egt limit really fast and cutting power quickly even when it isnt hot outside.

@97B4TDi If it's possible you should add another option on the poll:

Haven't upgraded yet but plan on doing so in the future.

I think the earliest cars were most susceptible, the 2009/10 cars being the worst. If you're newer than that I'd probably just focus on other things and take care of the CP3 upgrade when you do a timing belt or go stage 3+ and need extra fuel.
