There's an online Recall checker on the BMW Australia website.
You can search for any outstanding recalls for your car by entering either the Rego number or VIN:
https://www.bmw.com.au/recall
If recalls are found, the checker allows you to submit an enquiry to your preferred BMW dealer.
The major recall at the moment is the Takata Airbag Safety Recall. Although my car is not affected by the Takata recall, I found 2 other recalls which I assume to be minor.
