Body Control Module Bad?
Hello,
I believe I have a bad body control module on a 2014 428i xDrive convertible. Initially the radio quit working sporadically over the course of a week. I replaced the battery and reset the battery life. Over the next week, the radio quite completely along with numerous other functions. All fuses under the hood and in the trunk are good. Currently here is what is not working: 1. Driver Information Display is dark and occasionally shows "No Signal" 2. The rear turn signal lights do not work and after 1 flash the front turn signal goes to hyper flash. 3. Adaptive headlights do not work (move up and down, sideways) 4. Bright Lights do not work 5. Seats controls do not work 6. Cooling fan runs all the time 7. Gas gage went to empty and will not move (tank is full) 8. Climate control does not work (does not turn on) When I check the systems with the code reader, none of the systems show available Dash warning message pictures included. Again, I am leaning towards a body control module replacement. Can someone confirm this is the right direction for a fix or give me another direction? TIA Bill.. .. . |

Have you tried using ISTA?
You will quickly see which ECU is not responding, you can even run diagnostics to find the fault

Honestly, this is the first I heard of ISTA. I will be purchasing it and I will give it a try as soon as I get back home from Mexico this weekend.
Thank you very much!! |

With ISTA you have the ECU tree, you can directly see which one contains errors and which one does not respond
