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.

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...

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.

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.

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. Last edited by Rajmun340; 07-07-2017 at 09:45 AM.. |

#16 goes on water pump. Impossible to be oil only.

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.
