Hello, we have an F12 650i convertible Bj 02/2012, which was originally intended for Italy and therefore did not install seat heating. The car has the comfort seats installed and according to BMW there is neither for the comfort seats nor for the comfort seat module or seat control unit a part number WITHOUT seat heating. So we assume that the car has the heating mats in the seats, but these are not connected and that in addition the climate control part because of the lack of keys for the seat heating has to be replaced. In addition, probably also the corresponding coding, since the car then still does not know that it has a seat heating. My questions are: – Does someone already have experience with the topic here and can confirm that a seat heating is always installed in the comfort seats? – BMW suspects that even all cables are already lying and possibly are already connected to the seat and seat module, as well as to the cable harness and that you only have the plugs behind the K I’m interested in your experiences. Perhaps someone has had experiences with the comfort seats of another BMW model and can help? My plan is now first to expand the climate control panel at the next WE and to see if there are really the right plugs for the seat heating behind it. Paral I also want to check on the seat module if all plugs are occupied. Thanks in advance and greeting Marc
