5k dilemma

[Mark Trank <mtrank%acva@mail.co.albemarle.va.us>]

So.......I'm driving home after a couple of hours sweating it out on the 
tennis court after work......its finally cooled down in torrid central 
Virginia....grateful dead is on the tape machine...all is indeed 
well......but all of a sudden, the clutch pedal on my 5K goes strangely 
passive and mushy, all the way down to the floor, seemingly losing 
hydraulic pressure.  I stop the car, lift the pedal back into position, 
and away I go, no more problem.  When I arrive home, the battery warning 
light starts to flicker.  This morning, car starts just fine, but oil 
warning light comes on briefly.  

Does anyone discern a connection between these seemingly random events?  
Anyone encounter similar phenomena on a warm summer eve in his/her 
quattro?

Also, BTW, I've noticed in my little home town a plethora of audis on the 
road in recent days.  Not your upscale A4s and A6s, but lots of 4ks, 5ks, 
100s, even a couple of real nice 200tqs.  I usually don't see that many 
around here.  Just an observation........

TIA,
Mark
