X-post, horns not working...FEM module?

Gunzy · 03-15-2024, 10:34 AM

Hey all, I have a 2018 LCI and both horns don’t. They haven’t worked since I bought it and just recently had to the hit the horn and nothing happened.

I bought 2 new OEM horns and this changed nothing.

Could be a bad FEM module or clockspring? I’ve ran codes and there is nothing.

Maybe a clockspring?

I’ve read that possibly the LCI does not have a fuse for the horns anymore. Does anyone have any suggestions what to check?

I will check codes with BimmerCode, any clues for which modules to run?

Thanks!

Update: not electrical related per say, the horn ground behind the airbag was caught between the airbag and spring mechanism for the horn.
