I looked for a fix to this very simple problem, but was not able to find any videos or solutions. However, I did find a decal that would solve the problem for me! It was $10 for 2 of them and all you have to do is remove the old residue, clean the button with rubbing alcohol and put the new one on. If yours is as bad as mine, you will have to color in the edges, but if it isn’t scrape a little less than what I did. The start/stop button on this BMW i3 is now fixed and is actually transparent where the words are, so it looks like OEM.
