CODING VAG GROUP
Volkswagen/Audi group manipulated their ECU software to trick pre-production tests into thinking that their vehicles produced less emissions than they did. When they were found out, a software update/callback was released to owners with affected vehicles. This fix was for the 1.2, 1.6 and 2.0 TDI Volkswagen, Audi, SEAT and Skoda vehicles. Many owners who have had the callback software update are reporting/suffering with vehicle part malfunctions and issues.
