replaced rear pads for a friend on a 2012 a7. had no idea about needing to use vagcom to retract the ebrake. I've never worked on these and used a hammer to get the caliper.off the rotor. 1st mistake. then used pressure and a piston tool to turn the piston back in. got the new pads in and everything works fine but the brake light won't go out. is there anything I can do. also yes I'm an idiot I can't believe how much I fudged this up
