Hi all,

Need some help with INPA and catalytic converter desulfurization for my N43 engine cat.

Through the INPA software, there is meant to be an program option to desulfurize the cat, whereby you can force the process to remove the check engine light.

As you can see in the images below, it is not available for me. I have also tried the mikes tools version of INPA and that didn't have anything come up on the menu period. Does anyone know how to either a) fix this or b) an alternate way to desulfurize the cat so I can clear this light.

Thank you.

Hi mate, did you figure this out? I also can't select F9 or Shift+F3 for my 318i. Cheers

EDIT: I figured it out - you have to download the updated MSD80 files for N43 from bimmerprofs: https://bimmerprofs.com/msd80-loader-2-023/
