If by newer q's you mean cars like the A4, they don't need this button
since they have Electronic Differential Lock.  This is a similar system to
that used on the M-class Mercedes except only on two wheels.  The ABS
system applies the brake to a spinning wheel thereby transferring thr
torque to the other wheel.
