Tbh I didn’t even think of the bongs before I decided to fit the badge. Think that shows how few problems I’ve had.
The sensor has been absolutely fine since doing the badge, no issues at all (famous last words eh). You really don’t have to touch the sensor at all. I certainly wouldn’t have unplugged it as some of the videos show. There’s plenty of room to do the work without unplugging everything.
The worst bit was taking the front section of trim off but once you work out where the clips are, it’s pretty painless.
