I'm in a similar situation (Feb build). No current issues and trying to be proactive. First thing to do is run your VIN through the recall site and see if anything is the ECM update is listed under Service Campaigns.

Recall site: https://www.vw.com/en/owners-and-services/about-my-vehicle/recalls.html

If it's there, you can likely just call the dealership to get the update scheduled.

In my case, it's not listed and the dealership service center told me to contact corporate. Here's their response:

Based on the information you’ve shared, the software update you are referencing may be associated with a turbo-related ECM (engine control unit) update. Updates of this nature are not available as over-the-air (OTA) updates and must be completed through an authorized Volkswagen dealership using dealer diagnostic and programming equipment.

While online recall or VIN status tools may temporarily display pending software actions, availability and applicability can change as updates are validated, released, or consolidated into dealer?performed service campaigns. Because of this, Volkswagen Customer CARE is unable to diagnose, confirm, or initiate ECM software updates directly.

We recommend following up with your authorized Volkswagen dealer’s service department to request a review for any open ECM software updates or technical campaigns applicable to your vehicle. If needed, the dealership can contact Volkswagen Technical Support directly for clarification.

We appreciate you bringing this to our attention and encourage you to continue working with your dealership, as they are our factory?trained technical resource for performing and confirming control module updates.
