Radiator Shutter Activation:Line Disconnection 002E82

[E70xDrive]

Hello Everyone,

Please help me fix my 2012 E70 xdrive 35i. I will be very thankful. I changed alternator on my car, cleaned intake valves, changed valve cover gaskets and then tried to run the car. It drove totally fine for a few miles and than engine light came on. I ran diagnostics using ISTA-D. There are a few error codes and this is the first one I want to work on.

002E82- Radiator Shutter Activation: Line disconnected.

Does anyone know where radiator shutters are located and which line is disconnected? I have researched for few days and have not found relevant information. People on the forums talk about manually closing the shutters but where are these shutters located. My car doesn’t have active grill.
