Was used to it being a notch down. Doesn't seem to exceed this level.

I don't think my oil temp has ever gotten that high. How were you driving?

In Dynamic S mode, yes, it reaches that temp easily if been driven for quite a while in local traffic. The out side temp indicates 71F so it's not winter time any more.

The oil is cooled by the coolant, so it should be at the coolant temp or higher once up to temp. The target coolant temp is 105°C+ (221°F+) for low speed / low torque scenario. The passive thermostat opens at 113°C (235°F). The active thermostat is managed to control the coolant temp between 85°C and 105°C+ based on engine speed vs output. The coolant temp matrix for the original Gen3 (B8.5):



Is that display a smooth sliding bar, or does it move in chucks?

@SMac770 Thanks! It's small chunks. I'd say maybe 5-8 levels between 190 and 240 deg F. It does seem a little high after looking at your chart?

@minmet Thanks. Do you have the same top temp? Anyone else?

@A4Driver Normal city driving with some heavy accel for merging.

I have never seen it that high.

minmet

Yes. Exactly that temp close to 240F in stop and go rush hours especially in summer time. You wouldn’t see that often in D though.

I don't see it as outside spec. I could see it as being at the top end of the normal temp range. But you'd need to dig into the measuring values and log the coolant and oil temps and see how they compare over the duration of a drive and such. The pic gives us no information about the temps of the coolant and oil or the radiator fan activation or the vehicle movement for the five minutes leading up to the pic. There's also probably measuring values for that managed thermostat and other things to analyze.

I've had the car up to 120C (250F) on the track. But not just merging in traffic.

Thanks all. I've ordered obd11 and will report back soon with more data and hopefully some graphs.
