Do you know if the wiring for the rear heated seats are there because i read that the wiring to the heated seats has to also be changed during this 4 zone climate control retrofit? Also do you have the wiring diagrams? Last edited by SocomCA; 10-08-2022 at 10:50 AM.. |

Unfortunately, I don't have a wiring diagram, I haven't gotten it yet! I'm a bit worried about the two different rear climate controls (fan and fanless), since i was originally without a fan, will it work with the fan version, will it be programmable? Thanks |

They have both the heating elements, and temp sensors in them...so those are necessary for error free factory operation.... Good catch. |

Did you take pictures of your install during the install? Also do you know if the rear screen controller will work without the hvac install? i want to hold off on the hvac install until later and plan on installing the center console blower motor + climate controller with screen + foot well sensors and wiring. Will i be able to control anything with the climate controller without the 4 zone hvac change?? I don't plan on doing the b pillar install or carpet change |

Sorry need todo a question
Its extremely hard to find Interior Heaters 2hand- Distribution housing, a/c unit, lower 64119241199 Searching for F10/F11 with 4 Zones, I have been finding that a lot have 11 actuators instead of 13. With 13 i could only find one of endless weeks searching. - They are not expensive 50-100€, the transport is expensive +100€ This two are controlled by the top actuators. - 11 Actuators M23 M22 But i can also find in TIS that F01 + F02 + F07 had M22 + M23 = 13 Actuators. Confuse there are 2 versions of 4 Climate Zones? The other point is For F10/F11 LCI the Distribution housing, a/c unit, lower that supports the actuators is the following Autom. climate control with 4-zone ctrl S4NBA=Yes Distribution housing, a/c with preheater 1 03/2013 64119241199 The only Cars compatible are F06 Grand Coupe If I try to buy a brand new Distribution housing with 4 Zones, it comes with support for 11 Actuators not 13. But If we look at the actuators needed Maybe we can assemble 13 instead of 11 and all i need todo is adapt the wiring. https://www.newtis.info/tisv2/a/en/f...ion/1VnbhzL6Ge Last edited by Napas; 07-09-2023 at 07:19 AM.. |

The rear HVAC controller (FKA) is a slave to the front HVAC controller (IHKA), and needs to be coded for it to function 100%. Not doing so will have unpredictable operation, so not sure I can provide a definitive answer, but since the adjustments in the FKA is done for flap adjustments, which is controlled through the IHKA, minimally you may not get the intended air flap operation. Leaving off the B-pillar HW will have almost no ill effect on the system. I wish I hadn't done it myself, but since I did, it's staying installed. Last edited by M_Bimmer; 07-09-2023 at 08:45 PM.. |

So im thinking of only doing the partial 4 zone climate control retrofit mainly to increase the air flow for the rear while keeping the original heated seats function but without additional footwell heating modules or anything. According to this thread, they said: https://www.bimmerfest.com/threads/2...ir-con.828555/ Parts: Front grille with 4 zone climate control 64229166891 Rear Center Console Cover 51169206781 Rear Blower 64119311853 Rear Center grill 64229172344 4-zone rear controller w/ seat heating, w/o ceramic knobs - 61319290751 4-zone center console, storage compartment (qty 1) - 51169206729 On the electrical part 1) Connectors and cable from rear center control unit to the rear center grille vent. 2) Connectors and cable from the rear blower to the rear center control unit. 3) Power for the rear center control unit to be taken from the front fuse box (behind the glove box). 4) Power for the rear blower to be taken from the rear fuse box (at the trunk). 5) Power for the lighting on the rear center grille vent to be taken from the LED lighting for the center storage box. 6) Connection to CAN bus. 7) For heated rear seats, run LIN bus wires from the two rear seat heater controllers to the JBE. Is there anything else I'm missing to accomplish just control air flow from the center console blower to increase the airflow based on what the front driver setting is? |

If you are asking me how to get the rear climate controller to "just" control the center console fan speed, I have no idea. The system is complex and with my Engineering background, I couldn't convince myself that a predictable functionality could be achieved with only a partial installation.
If you proceed, and are successful with a partial install of the 4-zone, please post. Others most certainly would LOVE to hear about your accomplishment. The "others" that post on partial install, oddly, don't post anything afterwards on what does or doesn't work. Last edited by M_Bimmer; 01-14-2024 at 12:22 PM.. |
