Steering wheel shaking + squeeking temp sensor fan

[Grant Lenahan]

The shake is [probably] either:

1. warped, not worn, rotors
2. suspension bushings so loose that things move about under pressure
before you replace, spin and measure runout

Oh - could also be surface material on rotors - this is a modern S4 
problem - rust and pad debris get fused to the rotor surface.  A few 
panic stops cleans much of it off.
