How did you know the oil cooler was missing on the 2011 model? Did you take any pictures of the engine compartment that can be used for verification?

Here is some more speculation:

(the picture of the engine with no oil cooler seems to be an older non-turbo 6-cyl 328i which of course never had any aux oil cooler)

Some confusion might come from this: There is a performance power pack that adds a left side radiator (not an oil cooler) and a 850W fan (but it is not available for the Z4 afaik)
