If replacing a fender, you just need to loosen the cover at the side and you can pull it back far enough to access the 3 bolts......don't have to remove the headlight or cover...
Negative sir you have to remove the bumper and the headlights in order to replace the fender, men just take your time and it Don. If you could sit down and watch a 2 and a half hour move you could find the time to get the job done
I got an B7 from 2014. My dad accidentally pushed one of the parking sensor in, behind the bumper. I guess the only way to put it back in place is to takr the bumper down, no?
