Volkswagen China is significantly overhauling its software strategy for the ID.4

This update is not available for the 2021 "First Edition" models via OTA yet. Those owners must visit a service center to have the central control unit manually flashed. However, VW China has confirmed that by April 2026, 100% of active ID.4s will be eligible.

🔌 Many owners of imported Chinese ID.4s are successfully updating via manual USB/flash drive flashing (like the recent 2974 and 2976 packages circulating in owner groups) or by visiting specialized local technicians.
