Hi everyone, some time ago I've been involved in a crash in which I broke the AC radiator. The mechanic replaced it and filled AC gas but now the AC isn't working anymore. He told me that the AC compressor has activated a sort of protection and locked up, so he told me I need to go to a bmw dealer to unlock it. Is this possible? I tried to read error codes using Bimmerlink but I'm not getting anything. Given that I have the obd-ethernet cable, is there something I can do with e-sys or other bmw software to fix it on my own?

I just searched in ISTA/Rheingold for some hints for a compressor protection lock, but i found nothing.
You can try to read the error memory with ISTA/Rheingold and there should be some errors for the compressor and solution tips. Here you can ask for ISTA/Rheingold: https://f30.bimmerpost.com/forums/sh...highlight=ISTA |

That's a lot of error messages.
But that's the only message related to your problem i think. Quote:
Did you try to delete the error memory? |

The compressor clearly isn't engaging, the rpm keeps stable when I press the AC button.. |
