Buzzing ECM solutions

Ok, I know there have been a few threads on this already. I am currently battling this issue. The cold weather seems to have worsened the buzzing. It's also intermittent - it will buzz like hell sometimes, and other times, it's quiet. That is making fixing the issue very difficult. I also realize the dealer is going to dismiss my concerns if the sound can't be replicated. I've tried putting a clamp on my ECM, but that hasn't worked. I know there are some who have done something with the bracket in the engine bay, but I haven't been able to figure out exactly what. I'd like to create an all purpose thread for this issue, I know I'm not alone. Can any of you who have tinkered with the bracket in the engine bay post pictures of what you did? Does anyone know if there is TSB or some other definitive fix the dealers have? I have seen several things mentioned in other threads, but then the people posting those things haven't followed up.

 

The early 2018 models can have a buzz noise from the engine ECU. The dealer would need to contact technical assistance and confirm the production date on your ECU if they determine that is the source of the buzz noise. This doesn't apply to 2017 and older models in case anyone else reads this.
