This 29 September 2015 video is called The man who lifted the lid on Volkswagen’s emissions scandal.
From the BBC today:
Should the engines contain a so-called “defeat device”, this could substantially widen the number of vehicles affected.
VW has been embroiled in a scandal over emissions test rigging on its EA 189 engines.
It said it was now looking into older versions of EA 288 engines.
The EPA discovered that certain engines were fitted with a cheat-device that could detect when the car was being tested and reduced emissions to improve results.
VW had previously said that the software was installed on cars with variants of the EA 189 diesel engine built to the “Euro 5” emissions standard.
The company is now checking whether models with the EA 288 diesel motor built to the same emissions standard may also have the software.
Newer EA 288 cars built to the “Euro 6” standard are said not to be affected.
The firm has set aside €6.5bn to cover the costs of the scandal but many analysts expect this will not be enough.
