Hi I've had this car for ages now, and up till recently, i didn't even know it should have the active radiator flaps in front of the actual rad,. (not till i read my codes and it said it had a fault with it)(cos it wasn't there), i had a few jobs to do on the old girl and , removed the front bumper to refit the headlights and indicators previously removed (condensation and blown ballast), and set on to fit the new shutter. the thing wont fit you cant fit it from the front of the car , as there is very little content on the 645 on utube has any one done this or know how to refit the blind to the old girl ,
i have other problems with this car but i thought id post this first, , as im looking at it
thanks
Steve

Reinstalling the active radiator flaps on a BMW 645 is a relatively straightforward process that can be done at home with basic tools and mechanical knowledge. Here's a step-by-step guide on how to do it:

Tools and Materials:

Torx T25 screwdriver
Flathead screwdriver
Socket set
Ratchet
Allen wrench
New active radiator flaps
Wire cutters or snips
Electrical tape
Instructions:

Remove the front bumper:

Start by disconnecting the negative battery terminal to prevent any electrical shorts.
Open the hood and locate the front bumper fasteners. There are a total of 10 fasteners, five on each side, and two at the bottom.
Use a Torx T25 screwdriver to loosen and remove the fasteners.
Carefully lift the front bumper to disengage it from the retaining clips.
Set the front bumper aside.
Access the radiator flap mechanism:

Remove the headlights and indicators if they are still attached.
Disconnect the electrical connector from the radiator flap motor.
Locate the two bolts that secure the radiator flap mechanism to the radiator support.
Use a socket set and ratchet to loosen and remove the bolts.
Install the new radiator flaps:

Carefully detach the old radiator flaps from the mechanism.
Align the new radiator flaps with the mechanism and secure them using the two bolts.
Reconnect the electrical connector to the radiator flap motor.
Reinstall the front bumper:

Carefully align the front bumper with the mounting points on the car.
Reinstall the fasteners using the Torx T25 screwdriver.
Ensure that the front bumper is properly secured and flush with the car's body.
Reconnect the battery:

Reconnect the negative battery terminal.
Start the car and check that the radiator flaps are functioning properly.

I've just noticed something, the picture of the "dirty" engine bay where the red screws are circled there are 2 screws directly in front , don't tell me my local Indy didn't see these?. is this where the active rad hold on to?.. were we trying to mount it too far back?
