For what it's worth, beginning with the 2018 model year a baffle has been included in the space between the front grill crossbars and the a/c condenser so that the vulnerable part is not visible from the front of the car (see linked photo), cannot be struck by road debris, and yet still receives the same flow of (redirected) air.
As best I can determine, only 2 air ducts have been available for all i3's
: part #51747306421 for i3's with the seat heating driver/passenger option (S494A) and part #51747296811 for i3's without this option. There is no air duct shown that became available with the 2018 model year.
I have found the grill which is described as "insert, air intake, center". However, I haven't been able find a baffle between the grill and air duct, so I assume that it's part of the air duct.
Our 2014 BEV without option S494A doesn't have this baffle whereas a local 2019 BEV with option S494A has the baffle. These i3's have different air ducts which is evidence that the baffle is part of the air duct for i3's with option S494A.
The owner of the 2019 BEV has noticed that this baffle opens and closes in our warm Hawaii weather thus exposing the A/C condenser to rock damage while open. However, he's doesn't know under what conditions the baffle is open or closed.
Because the baffle seems to exist only on i3's with option S494A, we're guessing that its operation is related to cold weather. Because the heat pump transfers heat from ambient air to the cabin when cabin heating is on, maybe the baffle closes to block really cold ambient air from passing through the A/C heat exchanger. However, no REx has a heat pump, so the A/C heat exchanger would not be used for cabin heating in a REx, yet a REx with option S494A has this baffle.
So I'm baffled by this baffle
