can't get him even nearly 120C no matter how long I drive

This seems backwards. Oil temp is usually higher than coolant temp. Anytime I’ve logged it that’s always been the case.

I hear ya! Never could get mine close to 120 as well.

This is quite strange. Generally the oil temp is around 10C higher than the coolant temp.

I wrote "nearly" which means they weren't the same and i didn't say which was higher when the car was warm.
As I remember the oil was the higher. I will check again on Saturday when i will bring my car back from the PPF shop.

What you will also notice is in Comfort mode both will be around 215F. When in Sport or higher, coolant drops to 165F and oil to 195F. I’ve never seen the gauge move specifically with oil or coolant temp. Seems to be an average as others have stated.

What are you guys using the get defined separate temps?

Today i could check the temps on a 200+ km trip, normal road speed and highway speed. In comfort the oil temp varied from 106-109 C, the water was 105-108 C. In sport the oil was 95-103 C, the water was 81-84 C. Outside temp was 15-17 degrees.
When it's in sport the water is significantly cooler than oil. At the same time the dashboard still shows around 95, that's why i think it shows only the oil temp. LCI.

Stupid question how did you get the water temp? So are you saying the temp reading on the dashboard is only oil temp or both?

I'm using OBDLink MX bluetooth adapter and different apps on my phone, so i can see both and other parameters too.

Per the manual and tech release I guess it is an average of the water & oil combined for the overall average eng temp......

If the engine oil or coolant, and thus the engine,
become too hot, a Check Control message
is displayed too."

I dont think mine has ever reached the "center" position though, really tends to be right around 200*F after 20-30 minutes of driving. My commute to work is about 20 minutes of stop and go traffic in >90*F temperature and the engine temp usualy doesnt reach much higher than 160.

The manual says this but I'm pretty sure it's wrong.
The LCI dash has a marked readout starting at 160F, 4 minor marks then a major mark that isn't labeled, and then another 4 minor marks and a major mark labeled 250F. I'm not quite sure how this scale is supposed to be read, since it's a 90 degree spread but 11 increments total (8 minor, 3 major, one of which isn't labeled). This would put each mark roughly 8.2 degrees?? Very strange; maybe the scale makes more sense in Celsius?

In any case, after warming mine up and then cruising on the highway for a while, it was sitting at the midpoint mark and then a mark or two past there. The midpoint would be roughly 201F, but two marks past is ~217F which is much higher than I would expect water temp to read on normal cruising. I also have no idea why the scale reads as high as it does (it goes past 250); water/coolant should *never* get that high since it will be exploding out of the expansion tank once it is past 250.

I wish the scale would be sensible and show actual temp starting from 50F or something sane. Instead, it just sits at "160F" when the car is still cold, which is complete bollocks.

Are you driving in sport or sport+? That puts the car into a more aggressive cooling profile and will hold coolant temps around 80C, heavily based on ambient air also.

Since the car has a combined water->oil and Air->oil heat exchanger coolant temps will affect oil temps as well.

Cookie,

My understanding is on the pre-LCI - cold/OK msg is coolant temp and the bar chart graphic with pointer indicates oil temp.

I've seen 'OK' msg and pointer still all way the to the left indicating coolant in range and oil temp isn't.

I wouldn't start "booting it" until oil temp is above coolant temp so as oil is lubricating and the coolant is primary for regulating the engine temperature.

I know air to oil heat exchanger is located on RHS front but whereabouts is water to oil heat exchanger on the M2 ?

Don't need numbers for oil temp. it's a gauge. Get a carista and Bimmerlink app if you want read outs

i was searching around for a bit, does the 2016 Dash have any kind of oil/coolant/engine temperature gauge? i dont see it anywhere unless i have to enable it somehow.


EDIT: NVM found it -.-

Yes, this is correct. Comfort mode will fluctuate temps around 210-220F and will be lower the more aggressive your settings (sport, sport +)

I tried tracking this since I like seeing the mileage readout rather than the temp gauge.

When the car changes from COLD to OK, I've seen the oil temp at ~175F (or 80C for those like me that prefer Celsius). Several notches left of center... sorry its not scientific, but usually I'm not that eager to gun it (and my commute is short). I will try to pinpoint it sometime in the future.

[sh_kross]

I have a MY2018, and although I won't comment on whether it's an oil or coolant gauge, I have noticed a difference in cooling profile when driving in different modes.

I actually find it useful to drive around in Comfort Mode for a while, to warm the car up. Then after I'm past the first notch on the gauge I'll switch to Sport+ for more spirited driving. I noticed that I can't get it higher than that first notch, especially out of Comfort Mode. And if I switch to Sport or Sport+ it actually goes down to around that first notch after a couple of minutes of driving.

What I am curious about is if traction/MDM has the same cooling as Comfort? Or Sport? Or really what I want to know is will the car warm just as fast in traction/MDM as Comfort? If so I can stop using Comfort to warm up the car...

It warms just as fast in traction mode. On DSC off it has the same increased cooling as Sport though.
