G12 radiator blind flaps

 I know we are missing the front bumper and kidney grills,,,,I already removed them on this G12,,,,car came in with check engine light,,,,fault was radiator blind flaps not working,,,,since this was a new model car BMW didn’t have a test plan for this problem,,,,also no repair instructions on this,,,,so I was on my own to tear this car apart. Not o get off the subject but you see those 2 white canvas straps going around the front of the car,,,those straps are there to help with a 45 degree front end accident,,,,it’s there to keep all the front end piece together and not fly apart during a front accident at 45 degree. So here he new front radiator blinds,,,this is the back side with the motor in the center. When replacing the radiator blind flaps you also have to replace the lower radiator blind flaps at the same time,,,,because they work together and because parts department said they are sold in pairs. Here you can see the motor linked to the blind flaps,,,,this motor is activated due to temp and or a/c settings,,,,when a/c is on the flaps open up. Here’s a better picture of the flaps connected to the motor and all the other flaps linked together ,,,all this for emissions just to help heat up the engine faster.

    Good work man! I was just wondering. On a job like this when even BMW does not have any procedures or test plan on repair. How many hours do they pay you?

    hi, my 2016 750i xdrive just had the check engine light come on and dealer diagnosed the fault to upper radiator blinds inoperable. My car is under CPO but they are telling me it is not covered by CPO; I am quoted about $1050 plus taxes. It is an electric part so why wouldnt it be covered? The front bumper must be taken off for this? Is that why the difference between the cost of the part and the labor is about $180×3 hours?


    • It should be covered under CPO since it is electrical,,,,also they should only replace the actuator motor instead of the complete radiator blind with motor,,,,we only replace the complete radiator blinds when the shutter blinds are damaged or binding.

    Hi, similar to Jay, my 2016 750i xdrive also had an engine light go off & the dealer diagnosed an upper radiator blind drive as the culprit with a $1300 price tag for replacement. What are my options here as you’ve indicated that I don’t need to replace the complete radiator blind with motor but instead only the actuator motor. If so, how much effort would that be? Is that only an hour worth of labor & thus cheaper?


    • Labor about 2hrs maybe 2.5hr and then just the actuator motor which moves the flaps,,,,this is what BMW has us replace for repairs that cars are still under warranty,,,the only reason to replace the blind shutter flaps if they are damaged or broken or jammed.
