New Quattro owner

[scot@phoenix.phoenix.net (Scot VanAlstine)]

 I've just purchased an '86 4000cs Quattro.  I have a few questions
(possibly dumb ones).  On the console next to the diagram of 4 wheels is a
knob that is marked 1 and 2.  Does this switch from all,front or rear wheel
drive?  If so when should I use it? What do the lights mean on the diagram?


Outside door handles on the front doors don't work.  I've ordered repair
kits.  Any tips on repairing these?

When braking and turning the wheel, I hear a slight bumping noise.  When
turning the wheel and accelerating from a stand still I hear a clattering
noise like a CV joint.  DO these go out very often on Quattros?  I've
changed them on rabbits and porsches.  Do the Quattros have any gremlins I
should know about?

Well thats about all the questions I have for now.  Thanks for any help.
