Oil temperature super low and fluctuations- no op temp
Guys,
I have been having this issue where my oil temp gauge on the right side of dash will barely move and it fluctuates many all over but in low range. It happened ever since I got car. I don't believe it's tune based. It happened when I got the car with dinan stage 2 module. I put to stock and then stage 2 bm3. Then I put to stock for a drive to test again and it still barely registered. So I do not believe it is tune based I also have LED wheel where I can see obd2 reading for oil and water temps. It's always low. It's like 150 max to 160 on hour + drives. Drove 7 hours and max temps 170 I saw. It will jump up to like 170 for a second but then falls to like 155 and rhe needle does follow accordingly... so the needle will follow at 160 if ob2 says 160. It will follow to 170 of obd2 says 170... so it does work but it just never heats up. Never really seen 180+ only a few times for like 5 seconds. Does anyone have any ideas what this could be? I changed the oil thermostat to a brand new OEM on I got from my father in law that works in bmw parts counter... it also did not help and had the same issue and that thermostat was leaking from factory so took it off as it didn't change My issue anyway. I also see my water/ coolant very low sometimes too. Like it's already cooling at like 170 or so and doesn't get to 200. Like thermostat opens way too early or is stuck I'm having a hell of a time trying diagnose this... please... anyone have any experience and good feed back? I'm losing my mind. I can't even check my oil 90% of time because the car thinks it's still cold |

The sensor that you mention is coolant. |

Yes but were they also having issues with measuring oil? I can still measure my oil as long as it's above 150 degrees. I already changed that sensor in the front there that you circled in red hoping it would help. It did not. There is also this oil temp sensor on the side of the block that I need to try. |

It is a sensor that can be used for oil and coolant. I don't have any literature, speak from experience. |
