[urq] Wet floors - causes?

[Claus Vegener]

In the instruction book / owners manual Audi advice locking of the diff for 
high speed highway driving and for slippery weather.
Besides this, the Urq dont have a load assisted brake regulator for the back 
but only a fixed springvalve and the 10mm back discs are almost always rusty 
do to non activ braking. So "free-running" the rear wheels dont add in 
braking but with locked center they do.
