The thermostat may fail resulting in engine overheating and/or illumination of the Check Engine Light. Replacement of the thermostat along with a complete inspection of the cooling system will be necessary to correct this concern.

Overheating can cause severe engine damage. If the engine begins to overheat it is recommended to stop at the first available location and have your vehicle towed to a repair shop.

    Amber temp light illuminated. Then went off. It came on again 10 minutes later and quickly changed to red. After cooling, took it to closest mechanic (2 mi) for a quick look. Had towed to BMW mechanic. Determined to be electric water pump and/or thermostat. Told have to remove water pump to get to thermostat so might as well replace both.

    Car was over heating so I bought a new water pump and thermostat on eBay for $400, followed the instructions on YouTube and managed to fix the problem myself.

    Same problem as another customer. The amber temp light came on, quickly turning to red. Took to mechanic and at first he could not find the problem. Took back and he determined that the thermostat was stuck and needed replacing. I don't have the car yet, so I hope that the new thermostat will solve the problem.
