With OEM instruments, there is no way to read engine temperature from the cabin. On most BMW models, it has been like way for a very long time.

About a month ago, I got a 2016 X5 35i with only 75k miles. When I went to the dealer for my pre-purchase examination, the bmw master tech showed me the Control unit tree, which was at the time completely green and problem-free.
When I was driving yesterday, I noticed that the heat in the car was not working, that the engine temperature was staying at the lowest setting, and that there was a loud noise coming from outside. It turned out that the fan was running at full speed the entire time I was driving, which was for about 15 minutes. FYI, while I was driving home, the fan didn’t come on, but I did get a CEL, and the engine temperature rose extremely slowly and never reached the regular operating temperature.
I arrived at home and performed my scans; I will begin with the coolant temperature sensor. If you have any suggestions or know of anything else, please let me know. Could there also be a thermostat problem here?
the OBD2 codes
I’m also getting a message about the battery being old for some strange reason, which is strange. I typically have the car connected to a “intelligent” trickle charger if I won’t be driving it for a week.
Remember that the oil temperature on the dash is higher than the coolant temperature. I would attempt to fix all ISTA issues, then drive around the block to see what results.
Quick update: I spent $50 on an OEM BMW sensor to replace the coolant temperature sensor. Replaced it, removed the codes, and has been driving smoothly for the past three weeks.
CEL reactivated with the same two codes:
As an FYI, the engine oil temperature indicator is operating normally, and the fan isn’t running constantly like it did at first.
In order to continue documenting in this topic, there are several people with the same problem in the linked thread who replaced their thermostats but the problem persisted. However, this was stated on a poster, which is encouraging:
“They started by replacing the MAP thermostat for me, PN 11-53-8-635-689. That had no effect, and the car was still taking too long to reach operating temperature. Even after a 30 to 40 minute drive, the oil temperature would remain at the lower end of the gauge at 70C. Additionally, I experienced recurrent check engine lights for the P0128 and U1408 codes.
I returned it to the dealer, and they changed the heat exchanger (auto transmission oil cooler) with part number 17-21-7-600-553. On this component, a second thermostat malfunctioned. That fixed the issue. Even in really cold conditions, my car now warms up to operating temperature after about 10 minutes of highway driving.
I can’t find it right now, but you can find evidence of this issue online if you search for it.”
I also question the veracity of what was said by another poster:
A 10-year, 120,000-mile extended warranty is available for stuck-open thermostats.
Not bad, they went another three weeks without a CEL, drove another 1,000 kilometers, and returned.
This morning, I received the exact same two codes: weak acceleration and full-speed fans. Did you manage to resolve this completely, and if so, what was the outcome?
What level should the 2014 x5 35d’s engine temperature be at? Running at 155* right now. My Volkswagen runs approximately 190* at idling, so I think that’s a little low.
Where do you acquire the engine’s temperature? That’s not engine temperature if you’re staring at the tiny indicator on the far right of your instrument panel.
If there is a thermometer protruding out of an oil can, that gauge represents your oil temperature, according to the small icon. Your engine COOLANT gauge is displayed if the icon is a thermometer poking out of wavy lines (indicating water).
Once more, where are you receiving this 155deg F temperature from? Is it a program or app, the far right indicator on your cluster, or something else?
How can I monitor the temperature of my engine?
- Make sure the engine and radiator are cool, then park your car on a flat surface.
- Start the engine of your car and let it idle.
- Take a temperature reading from the engine block (also known as the cylinder block) and the upper radiator hose using a cooking thermometer or a hydrometer. The thermostat housing will be connected to the other end of this hose.
- Repeat the reading on both parts after waiting for about 10 minutes. Compare these outcomes to the earlier ones.
- Take another reading on both parts after waiting another 10 minutes. While the temperature of the upper radiator hose should not change, the temperature coming from the engine block should. Your vehicle’s thermostat is likely locked open if the engine block temperature does not fluctuate. This means that since the engine can’t achieve a certain temperature, you will probably need to change your car’s thermostat.
How hot should the engine in my BMW be?
The majority of experts concur that your engine should operate between 195 and 220 degrees. Your needle should always retain a position directly in the centre of your gauge.
On the BMW x1, where is the temperature gauge?
It’s not cool that after spending so much money on a “high-tech” vehicle, the designers neglected the fundamentals. Just cross our fingers that the temperature sensor never fails.
A temperature gauge is an anachronism, a holdover from the development of the automobile. The vehicle has so many sensors that it is more aware of everything that is happening inside and adjusts things accordingly. If the battery is not charged, the heated seats won’t operate, and the engine’s characteristics vary depending on the situation.
The next time you turn off your X1 in a quiet area, sit inside the vehicle and pay attention. The car is still in use long after you’ve removed the key.
The absence of a temperature gauge is due to the fact that the car will only do what it is given permission to do. The car should be the one to know the temperature, not you.
Be concerned about the electronics’ robustness and waterproofing rather than the lack of a temperature gauge:-)
Long after turning off the automobile, I’ve also heard faint whirring and clicking noises coming from it and wondered what it was up to. Does anyone have particular knowledge of what is going on at that moment?
if the engine overheats or a reservoir leaks. The engine’s temperature gauge trend is crucial. Due to his neglect of his temperature gauge, my father recently burned his engine. Maybe that’s why I’m anxious! By the way, it has now been established that the X1 does not include this feature or “relic”. Case is over!
By gaining access to the on-board computer’s private menu, perhaps the motor temperature might be determined.
I had a secret menu on my E39. The X1 shouldn’t be an exception therefore. The only issue is: how in the world do you get to it?
How can I measure the temperature of the engine coolant?
Using a thermometer is another approach to monitor the temperature of the engine coolant. An infrared thermometer should be used for this task. This kind of thermometer can take temperature readings without coming into touch with the subject of interest. You can avoid getting too close to surfaces that are extremely hot or cold in this way.
To get this procedure started, not much is required. Hand gloves and an infrared thermometer are required.
- Step 1: Open your car’s bonnet to see the engine first.
- Step 2: Next, search for the automobile engine thermostat. Put the ignition key in the ignition and walk over to your car to start the engine.
- 3. Get your infrared thermometer out and aim it towards the engine thermostat to measure the temperature.
- Step 4: During this, make sure the fan is functioning properly so that the temperature is between 180 and 220 degrees Fahrenheit.
- Step 5: If the engine is still hot, inspect the surface of the radiator for obstructions or problems. In this manner, the temperature ought to drop from one side to the other, indicating that the radiator needs to be replaced.
How can I tell if my BMW is overheating?
signs of heat exhaustion First, steam (which may initially appear as smoke) will emerge from the hood. Additionally, the engine temperature gauge on your dashboard could rise to “H” or turn red. For information on the precise symbol for your BMW model, consult your owner’s manual.
What symptoms indicate an overheating BMW x5?
Touching the hood is one of the simplest methods to spot an overheating engine. After ten seconds, if it is too hot to touch, the engine is probably overheating. Steam leaking from under the hood is another obvious sign that a BMW engine is overheating. When the coolant inside the reservoir begins to boil, steam is expelled, and this happens.
Is the engine temperature displayed on the dashboard?
Your car’s temperature gauge is made to gauge the coolant temperature in your engine. This gauge will indicate whether the coolant in your engine is cold, normal, or overheated. It is a crucial dial that may be found on your car’s dashboard.
What temperature causes a BMW to overheat?
Condenser fan motor, fan control module, or fan clutch. This results from running your engine past 3/4 on the temperature gauge (where 3/4 is 220 degrees). If this occurs, STOP right away and dial a tow truck.
Why does the BMW lack a temperature gauge?
Because the gauge needle would move around too much for the ordinary driver, BMW decided against including a coolant gauge. BMW decided not to include a coolant gauge in order to avoid confusing the typical driver. Before we begin to hammer it, we all simply wait till we see the oil temperature gauge begin to rise.
How can I tell if the thermostat in my BMW is broken?
The following symptoms indicate a faulty automobile thermostat: The engine overheats and the temperature indicator reads high. Temperature swings are frequent. The vehicle’s coolant seeps under the car or near the thermostat.
What leads to a BMW X5 overheating?
The radiator fan, a broken thermostat, or a coolant leak (water pump, radiator, hose, etc.) are the three most frequent causes of overheating in a BMW X5. fluid leak
Why does my BMW continually stating that the coolant is low?
You should take your automobile to the automotive service shop as soon as possible for an inspection and maintenance if your coolant is low because it could be an indication of a larger issue. Some of the causes of a possible coolant shortage in your car include the following:
- reservoir leak or overflow tank
- a radiator leak
- radiator hose leak
- water pump leak
- cracked or compromised radiator seal
- defective head gasket
What does the warning light for engine temperature mean?
When your vehicle’s engine temperature rises above the advised maximum temperature, the engine temperature warning light, which resembles a thermometer or simply says “TEMP,” lights. You should act immediately since an overheated engine can cause significant damage that is frequently irreparable.
This light typically alerts you to a significant issue at least somewhat in advance. For the next mile or two, keep a close eye on the light; if it doesn’t go out by then, pull over and turn off the engine. Leaks in the cooling system or overuse of the engine in hot weather are the two most prevalent causes of an overheated engine. In any case, your best course of action is to contact your neighborhood service center or emergency roadside assistance.
