Overview
- VW initiated the action on November 7, 2025, with Germany’s KBA monitoring it under reference 15666R and the company using internal code 93FK.
- The recall affects Touareg plug-in hybrids built from September 27, 2018, to August 21, 2024, including 4,853 vehicles in Germany.
- The fix is a free workshop-installed update to the high-voltage battery software that introduces on-board diagnostics, improves temperature monitoring, and can limit charging, with Audi indicating about 60 minutes for the visit.
- Drivers may see a warning such as “Bordnetz: Störung! Bitte Service aufsuchen” if the system detects an anomaly, and owners will be notified in writing, with the KBA handling notices in Germany.
- No property damage or injuries have been reported, and Audi’s quality checks first flagged changes in certain batteries, prompting a related Q7 recall and guidance to monitor for heat or unusual smells and to park outdoors until the update.
