BMW X3 Check Engine Light and/or Engine Overheating

(8 reports)

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.

Check engine light, code is for open T-stat circuit. -
high temp warning light came on while driving short distance (about 5 miles) then went down to normal. Check engine light came on after about a week of this. $1,200 repair at BMW dealership. Thermostat, coolant pipes all needed to be replaced. Disappointed with first BMW purchase; second coolant issue with it in six months. -
