F25 Auxiliary Heater retrofit
Hello! I have a 2011 f25 and have also installed the original one. Can you tell me how and where to record SHSX?
536 I already coded. Do I understand correctly that Webasto connected directly to IHKA pin11 |

Put SHSX in HO-Wort in VO. Also you must install LCI IHKA controls. Done that last week. I was wondering why it is not working until I installed new AC control panel |

What is the number of the IHKA that you installed? Can you tell me the wire from the webasto W-bus where you connected the IHKA? |

If you don’t know what is VO and HO-Wort how did you coded 536 option? These are basics
As far I know original Webasto from F25 uses LIN bus to communicate and it goes to plug A95*2B - PIN 11 I have put IHKA module with PN: 64116825513 |

Thank you! I will check what IHKA number is.
Which has to do with VO, I've missed it. Can you send me a picture of where you can find him or where to put him? Sorry if the question seems strange to you. I would like to post my pictures, but I don't understand how to reduce the resolution to 500kb, because larger pictures cannot be posted. |

IHKA controls it. |

RE: F25 Auxiliary Heater retrofit
So, I will post pictures of what I have activated, but the oven did not work.
Wads from Webasto go directly to IHKA on pin.11. I coded the CIC and activated the additional heater and it shows it. Also, I posted a picture from the Webasto diagnostic equipment about the Webasto stove itself and IHKA information. I also wanted to ask if there is something to write in the SHSX file? Tomorrow I will try to change the SHSX to OMSA as suggested by Krysiaman I attached the original FA file |
