[Q] Oil Temp Guage and misc

["SAQIB MAUSOOF" <SSMAUS@ccmail.monsanto.com>]

     I just bought an 87 4000 CS Quattro, against some people's advice and 
     I have not driven a car this fun to drive. My question concerns the 
     Oil Temp Guage near the ash tray. I have never seen anything like that 
     on a car and I am not sure how to read it. The manual says that the 
     range is 60 - 170 Celsius and the only warning is to not drive it 
     harshly if it is around 60 Celsius. Well, on a trip of 6 hours or so, 
     after a couple of hours I saw that the temperature was at 150, then 
     170 and then sometimes it would just go out of scale. No other warning 
     signs came on, anyone knows what is going on in here?
     
     Also, on the quattro switch, I can lock the central diffrential, the 
     light comes on, the position is 1, but when I switch to position 2, 
     i.e., the rear diffrential no lights come on. Any ideas
     
     Thanks in adavnce.
