Check coolant level alert

[BMWM3PWR]

i am getting this alert form the obc, i have a new radiator and do not have issues with over heating. is there a sensor i need to change?

Have you checked your coolant level?

The level sensors do fail, so it is not unheard of to get a new one.

if ur level is fine then the sensor at the bottom of the expansion tank is in need of changing

level is perfect. i just installed a mishimoto aluminum over the weekend. i will stop at the dealer to buy a new sensor for the expansion tank.

thanks
