Been removing front wheels for brake pad replacement on my Q5 using standard 17mm socket. Studs are ridiculously tight, assume air gunned previously. Using a 1/2 inch knuckle bar with extension tube. One side came off OK but have part rounded two studs on the other wheel. Tried a tighter 21/32" socket on a non damaged stud and it split with the force required (Britool original so not cheap tat). I'm not sure how best to proceed now so any advice welcome.
