Should i change the automatic transmission oil cooler for my BMW F30?

I’m not sure whether i should be changing the Automatic Transmission Oil Cooler as a preventive maintenance for my BMW F30 2014 with 188,000km mileage.

I live in Egypt, and the dealership usually change it at 120,000km as a form of preventive maintenance. So far i don’t have any problems so i’m not sure whether i should be changing it. Is this usual in other countries?
