I got the light when I disconnected the 12V battery when I snip the Fake speaker sound wire.
When I reconnected, the warning showed up and only disappeared after a long drive but always came back.
I recently disconnected the battery again to install paddle shifters on my 8sp DCT car and when I reconnected the battery, the warning went away and has been gone for the last 7-8 drives regardless of miles driven.
Try unplugging your battery, wait 1 hour and plugging it back in. I just pulled out the positive terminal
