BMW F25 Webasto retrofit problem
Hi
I have retrofitted a F25 2014 Webasto Auxiliary heater on my 2013 F25. The wiring and coding is done correct. But the heater does not start.. If I connect the heater directly to a Webasto diagnostic interface, the heater works GOOD! The heater I have installed (is for a 2014 F25): BMW part number: 64129330609 Webasto number: 9026939E The heater that is for a 2013 F25 (I think it is this model): BMW part number: 64122220985 Webasto number: 9024986A Both heaters communicate over LIN-BUS. Can it really be some difference with the heaters communication protocol? Any difference in LIN bus for a 2013 F25 and for a 2014 F25? Can I flash the Webasto ECU to a older revision? Thanks for any help I can get! Best Regards Mac |

RE: BMW F25 Webasto retrofit problem
Hi
It's a OEM heater. Yes SHSX and coded all ECU I have even hocked an Oscilloscope to the LIN-bus (IHKA connected to the webasto), I can verify that it try to send some LIN command, when I press the "start button". For me, it looks like my heater and my car does not use same protocol over LIN?!? |
