[A4] A4 Oil Temp Sensor

[thejimrose]

hey phil - the oil wouldn't cool down like that suddenly. the oil would take
a long time to cool down once hot. i bet what's happening is the sensor has
gone intermittent and when it loses connection, it shows cold oil.

not sure where the oil temp sensor is off the top of my head. searching the
forums [audiworld, audizine etc] should help.

sludge would have more of an effect on oil pressure not oil temps.

For a little while I've been getting intermittent readings from my oil temp
