Rolled 46,000 miles today, first problem - I think
So first off I have scheduled a service appointment and will update following.
My situation is this - I'm fairly certain that either my analog temperature gauge in the instrument cluster is not reading correctly or I have another issue. I think that in just a few minutes, 10 or so, my car used to (i.e. just a few days ago) warm to 250 degrees - 12 o'clock - on the gauge. I live in Boston so the time to reach operating temperature will vary by a few minutes depending on the wide range of temperatures we experience. Today after driving for almost 40 minutes the gauge registered 230 - I'm not sure if this topped out or if it would have kept going with a longer drive. I would say that it took at least 20 minutes for it to move off the lower limit stop. Interestingly the LEDs for tachometer behave as they always have - when the engine is cold there is a lower limit for red-line and it increases to the max red-line in the same amount of time it has since new. My question: Can you confirm your typical operating temperature is 250 degrees after warmup, and how long does it take to reach it? Thanks, Garrett |

Sport + has extra cooling to the engine, this feels normal to me. Its also been quite cold around the northeast lately

I appreciate the feedback, perhaps I am mistaken that it ever reached the middle - 250. I still do think it is taking (or at least appearing to take) an excessive amount of time to reach operating temperature. I will set a timer on my next drive and record the intervals from the point it moves off the lower limit, reaches the first interval (which is I think 190) and the point it reaches the second interval (which I think is 220).

I will concur with others depending on the throttle settings the motor runs at different oil temps up to about 60 degrees of change. Additionally, I have noticed the warm up times very according to outside temps. I wouldn't be shocked if its will run hot just to run hot, and do slow warm ups for a system/reliability test. Cold temps equal performance hot equals MPGs up to a certain point.
Has it throw any codes? The temp it appears can vary a lot. I would just take it in to see, but its unlikely you have an issue. But better staff than sorry. See this link below, its a common concern. http://f80.bimmerpost.com/forums/sho....php?t=1025229 Also I think this common among the BMW M, and maybe even the standard lineup. Note Post# 16: " I made a discovery today that i hadn't previously realized. I normally drive in Sport throttle and Sport Plus Steering. Well I decided to spend some time in Sport Plus throttle. The thing is I have a MPE Steering Wheel II with race display and normally leave the engine temp display on while the car warms up. The only thing is I noticed on normal application the engine was quite some amount lower than normal. It was clear the cooling systems were firing away in Sport Plus mode. I normally find in sport mode the engine water/oil temps reached and then maintains about 106-109c (223-228F). Today they stayed around the 84C/93C (183F/199F) in Sport Plus. To test this further I switched to Sport Plus from Sport and the water temp dropped fast from about 228F to 200F in about 45 seconds.

Same here, sometimes a hair above that, and a little below in Sport +

One other thing Ive found is that in the summer, Sport+ runs at a constant 190 and in the winter, it seems to run a bit warmer as the secondary cooler likely doesn't come on as its cold outside.
I run 250 in efficient and sport regardless of time of year. |

I know when its super cold out the car will take over 20 minutes to warm up unless i do some highway driving.

You guys are seriously paranoid.
Under normal conditions (economy, comfort, etc.) the motor (coolant) will aim to run between 200-250 degrees. Switching to sport+ mode will engage the thermostat a bit more aggressively and will try to keep the motor a bit cooler under the assumption that you will be pushing it closer to its limits. That being said you'll see coolant temps closer to 180-210 degrees. Cooler doesn't always mean better either, 220 is perfectly fine for this, or any, motor. Key number here is the oil temp, not coolant. |

Edited: Your temp sensor might be off, the oil pump could be malfunctioning, your water pump could have an issue (creating uneven cooling), etc....but almost any of those except the oil temp sensor would trigger warning lights.
Since you are based in MA, I'm assuming you are driving in some real winter temps. Under normal winter driving, the temp gauge will start to show >160 degree oil between 8-12 minutes after start-up with mild driving. 8 minutes representing active driving, 12 minutes representing more idling time. If you just idle your car from stone cold, perhaps it'll take longer than that. But your ultimate oil temps sound normalish to me. 220-230 is fine. 250 is a bit high, but also not problematic. I would check the oil level and go into your cars secret menu in dash to have it show actual digital oil temps as they move around. See if they are moving linearly and "look" how you'd expect ~6.5 quarts of oil to heat up in 20 degree ambient temps. |

Here ya go - here's the page when I posted pictures and some info on accessing the secret menu and someone else posted some more comprehensive links for the f30 platform. Just scroll down. Use this to see if your temp is varying in unlikely ways rather than rely solely on the analog gauge. |

Even flogging my car repeatedly up to 155 mph and down to 18 mph, then repeat 40-50 times, I never saw oil temps move above 230. Seriously good cooling on this car!

It takes 6-7 miles right now for my car to start warming up. This is in So. Cal as well. I think his car is fine.

Maybe paranoia is the operative word - cancelled my service appointment.
So Wednesday night I made the following observations, all settings in "economy", outside air temperature 41 degrees. Approximately 1-2 minutes of back roads followed by highway at 50-70mph. Both trips engine was completely cold Trip number one - 7 minutes until needle moved off 160, another 7 minutes until needle passed 190. Topped out at a hair over 220. Trip number two - 7 minutes until needle moved off 160, another 7 minutes until needle passed 190. Topped out at a hair over 220. All my concerns arose from a trip I made last Saturday - it felt like it took 20 minutes for the engine to even move off the lower limit, but I must just be losing it. I suspect that this is a result of my subconscious brain telling me that I have 4000 miles left on my warranty - which will probably carry me until end of April Then I have 5 months of lease left without warranty coverage. |
