CEL 12B701 Active Autowerke

[directmk]

HI All...looking for some help here.

I recently installed a active autowerke down pipe. First one produced a CEL (catless down pipe detected). They RMA'd that and sent me a newer one, a proto type of sorts and is labeled as such (see photo), but this one has a different O2 sensor port, angled differently than the previous one (see photo). My problem is that I am now getting a different CEL that says: 12b701 lambda probe heating after catalytic converter. resistance too high

Does anyone have any experience with that same error and what might the fix or problem be...short of the DP itself? This is for a 2022 MK5 3.0. with 23k miles and running on a jb4 tune if that matters.

thanks all!

It's the downpipe nothing else to it. Gotta tune it out.

See if you can get your money back and buy an Armytrix catless dp ASAP! No CEL over here for 23k miles on my car

replaced the O2 sensor, that did not fix the problem.

Open a warranty claim with active autowerke, their DP comes with a no CEL guarantee. if its the downpipe they will replace it for free.

quick question, how did it go with car inspection with the armytrix catless ? lol

I have had a catted AA DP on my car for well over 2 years now with no codes. My car passes NY inspection every year without issues. I do run ecutek but that should not matter here as nothing is coded out. I would double check the wiring for the O2 sensors and make sure something didnt get pinched during install.

edit: Make sure you dont have any exhaust leaks around the v-band, or O2 sensors.

In Georgia we don't get the physical inspections where they look for the downpipe. We just get a basic emission test for $14-20
