Check engine light came on a N20 saying engine temperature faulty,,,,checked connection ok,,,the sensor is located under the intake manifold you remove the intake pipe and throttle housing to gain access. 
Here is the old and new sensor,,,this sensor does oil pressure and oil temperature ,,,we see this sensor good bad once and awhile.

Hi ! I have a 2013 BMW X3…2 months ago had issues with oil pressure low message…so I replaced the oil pump, oil sensors, timing chain… drove for 2 months everything good – now low oil pressure light comes back on… oil level measures accurate… any ideas what is going on?

Possible a couple of things I would check,,,check your oil filter make sure it’s not coming apart,,,and the oil pressure switch that I showed in this blog could be bad

I have an issue with my 2013 BMW X3 28i Xdrive. I purchased the car used with only 86,000 miles on it. I took it to BMW because the system showed an oil change was due. Two weeks later I happened to look at the gauges and noticed the gauge was barely moving. I took it t back to BMW and they said it was the thermostat and replaced it. When I got the car back my screen stopped working and the gauge still doesn’t move. Could the issue be the sensor? I don’t think they checked it and I am hesitant to go back since I just purchased this vehicle and had no problems before I took it in for them to

When you say the gauges are you saying just the temperature gauge is not moving,,,, and the I drive screen is not working,,,it’s hard to say what the problem is without seeing any faults in the system,,,the temp gauge not moving is not a common issue,,,,the screen not working could be a couple of things.
