P1025
After replacing High pressure fuel pump, car drives great again.
It seem I have p1025 pending now. What is it p1025 related to?
I can’t find definitive answer anywhere.

I found this answer to clear:
Perform throttle adaptation and engine torque loss adaptation. You will find this function under DME using PIWIS tester.

Found another answer: The code will still be there because the adaption needs to be cleared. You can do a hard reset of the computer by touching the negative battery cable to the positive battery post for 5 minutes this will discharge the capacitors and reset the system. If this does not work then a shop will need to clear it.
Any opinions on this one?

Pending I believe means the code has been seen and not there now - and it will be removed after enough drive cycles are completed (ie: pending removal).. You won't clear it with battery crappola - that went out with discrete components. Emissions failures are supposed to hang around so places like NJ will spot them even if you've been touching battery terminals together. If you owned an iCarScan you could clear it yourself - at less than the cost of a dealer visit to have them clear it.

There is a lot of info in: https://www.renntech.org/forums/topi...p-replacement/ - including one person who had the same problems you did with a rebuilt pump - and apparently he replaced it again and the problems went away.
And this is the one you saw about connecting the battery cables together?: https://www.2carpros.com/questions/2...ne-check-light - I guess it can't hurt. DO take both off the battery to do this. No room for mistakes that way.

UPDATE: Tried the battery disconnect, I did not succeed as code is pending again, surely will pop up soon.
I spoke with a local Porsche specialist. I have an appointment Thursday morning and will update on the result for sure. 5-step adaption using the PIWIS will be the first step to address the P1025 fault code.
Failing primary fuel pump (the one in the tank, not HPFP) might be the other possibly, although less likely as I did not have P2015 prior the HPFP install.
Last possibility could be faulty HPFP, I doubt that one. We will see, can't wait to have this addressed.

UPDATE: All sorted. The adaption is suppose to be performed after the HPFP install. Everything went smoothly, some the the pressure values were bellow the factory range.
After the service, everything is back within the range. I drove bunch of miles, no pending codes and car drives even smoother. Good Bye P1025. SUCCESS :-)

P1025
Hello - I’m new here. I currently had the same issue and replaced my HPFP on my 09 GTS. I’m also getting the p1025. Can you share the estimated cost you spent to get the code cleared? I feel like my local
porsche dealer is a major rip off that wanted to charge me $1800 for the HPFP, whereas I drove to another dealer 45mins away and got it for $875. I just want to know how much to expect to pay just to clear the p1025 since I feel like my dealers are just marking up ridiculously.

Want to talk about silly prices. There is a intake pressure/temperature sensor on the turbos, located in the Y intake. For some reason I was curious what Porsche wants for it. I found it at several dealer websites..
Gaudin: https://www.gaudinporscheparts.com/o...r-99660618000/ - $343
Sonnen: https://www.pelicanparts.com/cgi-bin...996-606-180-00 - $331
Porsche Atlanta: https://www.porscheatlantaperimeterp...996-606-180-00 - $360
Turns out it's not "magic" - and is used on LOTS of turbo cars by lots of manufacturers.. (including an AC-Delco branded one that GM uses on the Corvette..)
Pelican: https://www.pelicanparts.com/cgi-bin...996-606-180-00 - $38.25
Google "Bosch 0261230042" which is the Bosch Part Number right on it - and you'll find it for $19.00
Markup? Nah... just about 1000%.
I'd love for someone to track down the OE part number for the HPFP.. I haven't been able to suss it out on photos I've found on the web - but bet it's on there somewhere along with a clue as to who makes it.

Before you do that, where did you get your HPF pump? You might have another issue.

Based on my WIN# the part numbers for HPFP for my 2009 GTS is 948-110-315-GX for the rebuilt unit (with core exchange). The new one is part# 948-110-315-07.
