Stupid Forward Collision light (ideas appreciated)

Last week my ‘24 AT4 had the forward collision light come on. I’ve searched and tried the suggestions (disconnect battery, mess with the fuse box, etc.). Today I had it in the shop for one little issue and just asked if they could fix that too. You would’ve thought I asked them to cure polio. They cleared the system…nothing. Fiddled with a couple of other things…nada. Had a guy in the waiting area said he had the same issue and could show me the fix. Same stuff I already tried with the settings feature. Now they want me to leave it for a couple more days so their “electronics specialist” can look at it. Is there anything else that someone has had success with in the group? It’s not THAT big of a deal because I don’t care about lane assist and such (cruise still works) but just seeing that amber beacon of light staring at me and mocking me is irritating. Thanks in advance for the suggestions!
