[s-cars] Multi Function Temp Sensor or Thermostat?

[Rich Beebe]

brian et al,

i noticed my water temps staying very low today (around the 2nd thin
mark), until i stopped at a red light (about 8 miles from the house),
at which point it rose to roughly to the first thick mark, iirc. what
you mentioned below about oil temps is what has me thinking, though.
my oil temp gauge never moves from the far left of the gauge. i
noticed this upon buying the car and was told that they all read
low and it's normal. 2 questions - where 'should' my oil gauge 'read'
and could i have a similar thermostat problem? tia.

rich <-- feeling bad for asking so many questions, but i'm new to audis.
