Mine goes past 210 all the time but doesn't stay at the high temp. This was just normal driving up to 4500 rpm on my way to EAS.

This was on D2 in auto mode.

How is that? My car has been to redline 12 times and never hit the rev limiter according to the data that's in the hidden file according to bpmsport when I had him do the euro dct programming.

Redlined 12 times...!! Yep, better order RBs and prepare replacement.

To OP, I wouldn't worry about it unless you're noticing changes in drivability or getting some sort of overheating warning lights/messages but that's just me. Make sure your coolant and oil level are good and enjoy the car.
Nearly 3,500 rpm in 6th gear and you are barely above 70 mph? My car is pulling about 80 mph in top gear at those revs.

i assume you're speaking to my picture/posting. Yes, with the DCT transmission, I would be around 80mph in 7th at 3,000 rpm...

I keep forgetting that the DCT has 7 ratios rather than 6... My mistake.

This is from stop and go traffic. Have noticed on mine it went right a tick from the middle. Coolant levels are max and oil was changed 1k miles ago.

I did not know that. my water gauge seldom goes above 195 at the most 200 then drops quickly to 195. the oil gauge in the cluster is frequently above 210. so when the track guys are at the third dot or slightly higher, does that mean it's still averaging both?
Hard to say dude. I think it would be good to start a baseline.....change the fluid and start documenting some things.
1-outside temp average for the time of driving from your cluster.
2-cars temp reading at the time
3-type of driving and flow ranking.
*city, freeway,
*flow rate 1=gridlock 10=wide open

I see higher temps on LA freeways that are 1-3 traffic flow along with 93 or higher outside temp. The heat from ground, car exhaust in front of me going through engine fan and low RPM's moving oil slower through the motor are to blame. The water pump is electronic so it can change flow rate based off temps but low oil movement and no clean cool air flow just adds heat.

It's not a combination gauge of oil and coolant. It's oil temp period. Might be labeled wrong in whatever application is being used.

Are you absolutely positive Mike? There are countless threads stating it's a mixture of the two going back to 08.

But what?

Just because the temperature sensors share the same part number automatically means that the gauge is giving some sort of combined reading?

The coolant temp sensor is 13 62 1 433 076 and is connected to the lower radiator hose on many BMWs, and is mounted in the thermostat on the M3. It's just a generic sensor with a reference voltage, it could be use for diff, transmission, or taking your temperature. This shouldn't lead to the conclusion that one sensor provides both values.

Think about it - how would one sensor give you a reading for both coolant and oil when they don't mix?

Having a "combined" sensor for both could be catastrophic. Oil and coolant heat up at dramatically different rates. You could have your coolant temps reach 212F before oil even reaches 120F.

Edit: Going to look more into this tomorrow. Oil temp sensor has got to be somewhere else. I'm going to unplug that connector just for kicks once I get my M3 back from the sideskirt install.

I suspect that the oil level sensor doubles as a temp sensor. The E60 M5 uses the same oil pan tube sensor and the M5Product-Info says : "The oil level and temperature are monitored by a thermal sensor."
It would make sense if both functions have been integrated together to save another wire and connector. I think the false assumption that oil temp shown on the dash gauge is derived from the coolant temp sensor developped over the years because of the absence of an oil sensor part in the list.

If the above can be confirmed then elevated oil temp on the gauge has to be the engine. This owners forum has shown over the years there is too much variability in S65 engines. Operating temperature is one more to add to the list. And no, it's not user and operating conditions induced it's B.M.W.

Maybe it's the location Mike? It is located in the water pump. But when you look through parts for oil temp gauges this is what comes up. Part #16. On older NON S65 Models it is located on the cylinder head.

It's impossible for a temperature sensor mounted in the water pump/thermostat housing to measure oil temperature. There are 2 seperate sensors, one for the engine coolant which triggers a warning lamp and another for oil temperature, which registers on the gauge. While the part numbers may be the same, it's like our engines' coils. The ignition coil for cylinder 1 does not have a different part number than the one for cylinder 2, et.al. They are the same part, just mounted in a different location. I'm not sure exactly where the oil temp sensor is located, but from diagrams it appears to be adjacent to the oil pump.

I challenge you to show part 13621433076 "Temperature sensor water/oil" mounted anywhere on S65/S85 engines where it is measuring oil temp. You won't find it. There is only 1 count of that part and it's on the waterpump thermostat housing not for the oil. As i said above, either the oil level sensor doubles as a temp sensor or there is no oil sensor directly measuring oil temp (unlikely).
