I confirmed the FA option $494, seat heating, is still there. I’m wondering if deleting and re-adding the option to the VO will return it to the default seat heating setup.

ard, I’ve seen the comfort seat requirement a lot while searching. I also read on one or two forums that dealers indicated sometime in 2011 the distribution function started getting restricted to comfort seats only (with one dealer/service advisor noting it was possible to add “with the right software changes”).

Since mine was an Oct 2010 build that has the original sport seats with no changes to interior, wiring, etc., I’m thinking they discontinued the functionality shortly after.

I got a chance to try a few other codes with no success, as expected. HVAC_SEATCLIMATE_LED did nothing, SITZHEIZUNG_IHKA was activated already, and I haven’t located most of the other codes yet. More to come. I have a feeling it’ll be a combination of codes that has something in common with comfort seat features, climate features or the iDrive controller.
