On one vehicle, a damaged roof may have been repaired with an incorrect part. As a result, the vehicle may not perform as designed in a severe crash. In particular, the roof could deform more than normal and the restraint system (head curtain airbag) may not work properly.
An incorrect roof repair could lead to an increased risk of injury in a crash.
Volkswagen will notify the owner by mail and instruct them to take their vehicle to a dealer to replace the roof reinforcement.
