Hi I replaced the temp sensor in my car and it’s still not working so I think it’s a problem with a fuse Mechanic's Assistant: Have you checked the connectors on the sensor itself?

Hello, my name is \*\*\*\*\* \*\*\*\*\* will be helping you with your BMW question today. While those faults both indicate improper cooling system performance, the root cause for this fault in the M52/M54 engines in BMWs is due to the thermostat hanging open. This will require replacing the thermostat assembly.

I replaced the thermostat in the assembly thingThe metal spring disk type thing

OE, OEM or other aftermarket. This is pretty important. If not BMW, Mahle, Calorstat or Wahler, then that can be the issue. Also, just so were sure, your scan tool...this has the ability to display coolant temperature? What is it displaying from warm up all the way through to operating temperature?

Hi when I start the car it displayed -40 c, it was like that before
Automotive Expert
Ok, that's what you're seeing on your scan tool, and it doesn't vary?

No that's what it shows on the car dash
Automotive Expert
wait, are you speaking of the outside temperature display? There is no coolant temp display that shows actual temperature in these.

The coolants at 55 ferinheit
Automotive Expert
Ok, but this -40 number you're seeing, that's in the LCD display at the bottom of the cluster, correct?

I also have a oil pressure light on but I can't get the code or anything for that
Automotive Expert
Ok, and is there a check engine light on currently? The reading in the LCD display is just showing outside temperature, and will not affect running characteristics of the engine.

Still not sure what you need?
