Volkswagen has started its long hard road to repair the damage caused by their emissions test cheating 'defeat device,' scandal. The company posted a video showing how they plan to fix millions of diesel powered vehicles in the 1.6 liter and 2.0 liter classes. Note that this video and the included remedies are for the UK, North American emissions regulations are different which means that this remedy, which takes 30 minutes per car to complete, may or may not apply here.
