I have a 2000 A6 2.7t. I was experiencing occasional high temps for oil (300-325) for a few min and then it would drop back down to about 225-250. The temps would drop in about a couple seconds, which i dont think is normal for oil to cool that fast. Lately i've noticed that my temps will go up and they sit around 300-325 all the time and rarely now do i see them come back down. Has anyone heard of the oil temp sensor going bad? What could be the problem here.

 

gauge could be bad ... temp sensors are knows to go on the cluster according to audi

 

hey do u know whats the normal temperature for the 98 audi a6 quattro ?

 

225 i think

 

Mine did the same thing ('01 A6 2.7t), right before it completely died and showed 0 temperature. The sending unit was the problem child; pretty easy to replace, thankfully.
You're right in thinking oil temps aren't going to swing that fast unless it's -40 or +150 outside.

i've seen the same thing on my 2000 2.8L. Where is the the sensor, or sender located?...i can't find it from the bentley manual.

 

bump...where is it?
