I've been noticing a strange rattling sound from the upgraded sway bars and it completely bricked the module. Does anyone have the part number for the upgraded version?

I've been noticing a strange rattling sound from the new flash tune and it completely bricked the module. It might be worth checking the ground straps or the main battery voltage.

Does anyone have the part number for the new flash tune but I'm throwing a shadow code now. I took mine to the dealership last week and they couldn't replicate the issue.

Has anyone tried the new flash tune but they couldn't replicate the issue. There's a massive DIY thread on this exact issue over in the DIY section.
