Tried searching a bit and didn't see this exact question pop up. Has anyone replaced or had to reinsert one of the sonar sensors? When I bought my 4R there was a scratch on the rear bumper. Dealer took it off and repainted it, but one of the four sensors didn't get reset all the way. I haven't had much time to play with it but figured I'd ask first if there was an easy way of popping it back in before I mess with it or take it to the dealer again.
