do you know exactly what the head rest restraint is for and does?
Head restraints were introduced in MY09, the methods are a bit different when coding for race seats in MY08 vs MY09-13. Seat position sensors are present in newer models as well as 1-series models.
OC3 is possible as well, not a problem. I haven't had the need to retrofit heated seats since the weather's typically nice all the time in SoCal, but should not be a roadblock at all in the retrofit path.
