[Es2] Re: [s-cars] clutch problem

[chris chambers]

Prior to my 93 UrS4 I owned an 86 4000 CS quattro. One cold and snowy
night the driver's side front CV joint blew out at the wheel.

Turned the knob to lock the rear end and drove home. Question is,
should such a situation arise in a UrS4 can you just press the button
to lock the rear end and drive keeping your speed below 25 mph?
