Absolutely wrong (the mechanic, that is).
Quattros (with the newer systems) default to 25% at each wheel.
The rear diff lock only locks the two rear wheels together to
provide extra stability for unsticking yourself if needed.
The older systems (with 3 diff locks) could allow most combinations
of wheels locked together.
But, at all times, this is an AWD car.
