Hey @Melonkanon, that comfort seat retrofit sounds awesome, but it's frustrating when you're left with a stubborn FRM fault code even when things are working. When you VO coded the module, what were the exact steps you took after adding the new options? Sharing a bit more about your process might help the coding gurus here figure out what's going on.

 

Hey! It's amazing! getting rid of those Standard seats

I connected the car with E-sys selecting the protocoll for F10 510 (there was a selection called 540 aswell)
Headed to Expert mode and Read the Vehicle Order. saved it, went to editors and FA Editors where i added the VO codes.
The file was then saved, i went back to "Expert mode-> Coding" Loaded the edited Vehicle order File and Activated it. i then went to SVT Actual -> Read (ECU)
I'm not a 100% sure if read the VCM or not.
Scrolled down to the FRM Module Clicked on "Detect CAF for SWE" selected the lasted CAFD "file"
Scrolled back down to the FRM and hit the "Code" Button Below
I replaced the IHKA from the old car (needed vented seats button) And Door panels with Memory + massage buttons.

I did the exact same procedure for my IHKA and SMFA SMFB Modules (seat modules) and they turned out with 0 faults.


I did end up adding adding a couple different VO codes for the seats.
455 Active Seats
453 Vented Seats
456 Comfort seats with memory
488 for Lumbar support
494 for Heated seats.
