It actually had a lot of codes which are attached. I deleted all and restarted and immediately read it again and first one that came back aline was 2936 coolant temp sensor, electrical short circuit to ground. After a minute code 33fe cane back engine oil pressure control plausibility, statuc: pressure too low. Engine sounds normal. Also code oil pump: pressure too low 3406. I monitored the scanner data, and the ect engine coolant temperature was 123f after 2-3 minutes of starting. I also just noticed 5 minutes later that there is white smoke from exhaust. Water level is full. Oil is full.

There are a few TSBs about the temperature sensors being an issue on them.
BMW SI M17 02 13 being the latest one.
https://dot.report/bulletins/MC-10146802-9999.pdf
I would look into that and then see if it was completed.
The fans will also come on if the temperature sensor signal is missing. As you are showing the error of it being shorted to ground that would cause the DME to say "I don't see a temperature signal, I better turn the cooling fans on to protect the engine" The temp sensor is a simple thermistor that varies in resistance as the temperature changes. On many cars you can unplug it and it will turn on the fans for the same reason. You say that it shows a warm engine in a few minutes which would be normal. From that and the other codes I would start hunting on the wiring harness for damage first. Look at sharp corners or hot spots. If a few wires in the harness were shorting you could get all this. The other possibility is a bad DME which is somewhat common on the minis. I would check the coolant sensor wiring first. Go into live data and watch the coolant temperature, then unplug the sensor. See if the temperature changes.

Good ideas, thanks. I also heard about oil getting into some PCM or DME wires, I just never found out where per the conversations I read.

Yeah, oil migration is a thing for sure. I've seen it with transmission connectors and a few throttle bodies where the seals were junk from the day they were installed.

I am almost finished changing the thermostat assembly. Also checked the back to see if there is any leak in the back sensor which the other code shows which has to do with another TSB I think. I don't know what it's called, but there is a harness that goes into a circular thing in the block and has one screw, the harness goes inside. TSB says to remove it and update it. But there is hardly any leak from it. Code 2DA0 points to one of the can sensors can you tell me where its located so I can remove it and clean it first.

The 2DA0 code is the same as a crank-cam correlation code in any other make but you mentioned a P1338 earlier. That would be a circuit code to the sensor, showing it shorted high. That would also set the other code. The sensor is on the top rear of the head in the middle of the cams.

I think I see it on back of head under the valve cover kind of, on passenger side. Can I replace it with the exhaust one to see if code comes back? Where is the exhaust one?

They should be next to each other if the service info on that engine is correct. They are the same sensor.

Not good to see that much debris in the oil. Might need to do a few rapid oil changes to get that out.

New thermostat and harness. New oil pressure sensor, new oil filter and oil. Started car and light for oil pressure immediately comes on and all types of codes. Engine is smooth. The fan still came on and same p117 code. Delete it and fan stops. No oil in the dme connectors sitting on top if engine on driver side. Other codes that set are below. Decided ti leave it for fee and then do a motor flush. Added it to the motor. Started the car and there was no red light and no check engine light came on. Strange. Left it running 5 minutes and now gonna change the oil again and see. But there are no codes after running the motor flush in it only the p117 pending. Even when the engine is off and ignition on fan stays on then I delete the code and it stops then 3 seconds later comes on then I delete the code and it comes back on.

Looked at live data and it shows ect at 285, but it's not overheating of course but that's why the fan stays on.

Okay, with live data up, unplug it. Does it change to -40 or what? With it unplugged short the two terminals what shows then?

First picture you provided shows an insulation part or something. Why are they using that? I only replaced the whole thermostat assembly. I assume the eenor that cane with it is what reads the ECT correct? I think it it has 2 connectors. Am guessing one is the sensor and other is to read thermostat?

If they are, they both connect then run to a bigger connector at main harness on two of them. I guess I can just unplug that and see if the temperature changes at all. And to short it I will plug it back and just remove the sensor harness and not the thermostat harness.

Remived the connector that sends wires to thermostat and to the sensor, temperature did not change on the scanner. Stayed at 64f. If it doesn't work, then how is it that I read 285 once?

If DME is bad is that the one on top by reservoir? The n driver side.
