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.

My thermostat needle was moving from even to hot (H) up and down as i drove. it stayed on hot for a few mins or until i stopped the car and turned off ignition and when i turned it back on it was fine. thought it was the thermostat sticking. It was fine for about a month and a half. Then started getting hot one day out of the blue. Once again the needle was not still for too long. This time went from H to C and back to H. Then finally overheated and turned off about 10 mins right when i got to a place i could pull over. We let it cool down and saw that it was out of water. We put water in it. It started and was fine for about 10 miles then overheated again. Pulled over again and filled up the radiator this time to the top. But car would not start back up. At the shop now.
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.
Got hot and it died well not start. Pushing antifreeze out of the radiator when the radiator cap is off
Overheating light only comes on when its cold outside. If you cut the car off it and wait a few minutes it stays off?
Then today one of the hoses blew off and I had it towed to the repair shop.
I had to have the thermostat, water pump, and coolant extension tank replaced all at the same time.
Temp light flashed, then red, as I attempted to pull off freeway radiator busted
Thermostat was already replaced at an earlier date when my check engine light trouble started. After a very expensive part replacement related to the exhaust, I found the light was still coming on. That repair was not needed. The real culprit was a fuze that went up.
thermostat failed causing check engine light. replaced thermostat
Overheat while driving on I15 south with outside temperature of 79.
thermostat light came on, let car cool, and than low coolant light came on.
Red overheat light appeared out of nowhere.
Service engine light stays on: have serviced engine, have replaced radiator twice, all upper and lower hoses, head gasket, machined the heads, replaced alternator, changed all plugs, replaced sensors, replaced ruptured expansion tank, replaced thermostat, now will clean injectors, (already seafomed them twice), check valve covers since the codes suggest misfiring on 4 of the cylinders, (seriously, I can hear the freaking car missing from a mile away), also we have a vac problem. Only run 93 octaine gasoline, keep full synthetic oil changed and use only OME filters. Only tow the car to the shop, will not allow her to run hot. So tired of borrowing my mom's 2003 Mercury Sable with over 175,000 on the odometer and still running great! (call her old reliable)
I have founded the BMW Caregivers /Survivors Support Group, and am looking for hospice and respite care for my bmmer! OH, THERE IS NO SOLUTION

Engine light on, took it in an have it replaced with only 65,000+ km. A little over 2 years later took it in again with the same problem. Now it is at 85,000km. Changed the whole thing which cost me a bundle. Either the part is defective or the workmanship not up to par. The thermostat should last longer than 2 years since it had lasted 65,000+ km the 1st time.
Won't turn over no start no crank nothing!!!!! What's the problem
sensor light came on. Put coolant in the tank, it came on again. Havent taken it to the dealer yet. Not looking forward to this.
