A report from Germany is claiming that German luxury carmaker Audi developed the software used by parent company Volkswagen to cheat emissions test in 1999.
According to the German newspaper Handelsblatt, Audi developed the software in 1999 but did not put it to use in any of its cars at that time.
However, 6 years later when the engineers at Wolfsburg based VW were unable to meet legal thresholds for Nitrous Oxide (NOx) emissions, they turned to the Audi developed software to help cheat emissions tests.
The software can turn off various engine functions which helped the cars pass emissions tests despite being way over the limit with regards to NOx emission levels.
Niether Volkswagen nor Audi have commented on the report, citing ongoing investigations by U.S. law firm Jones Day into the diesel emissions scandal.
The Volkswagen Emissions Scandal came to light in September 2015, after senior VW officials finally admitted to using defeat devices in their cars.
