In the i3 owner's manual, it shows two coolant reservoirs in the frunk, one for the climate control system and one for the "drive." I presume the "drive" reservoir is not for the Rex engine coolant. Is the Rex coolant reservoir in the rear under the engine cover near the oil dipstick? Thanks for the information.
 
same inquiry here.
i could not find a site that specifies what coolant is needed for the rex engine.
i went to a bmw dealership and i was provided with 2 different coolant.
I would assume the rex engine and the e-drive coolant are the same (blue color).
I bought my i3 preowned last dec2020, and was planning to check all coolant levels for peace of mind.
all my coolant levels at frunk are ok except in the rex engine which seems below minimum.
