Bosch Involvement in VW Diesel Emissions Scandal

Bosch Said to Have Played Critical Role in Volkswagen Diesel Emissions Scandal Since 2008

Auto supplier Robert Bosch has been accused of conspiring with Volkswagen to produce the technology that would help the German automaker fraudulently pass standard emissions tests in its diesel vehicles. Numerous media outlets, such as The New York Times, Fortune, Bloomberg, Thomson Reuters, and Jalopnik, have reported that Bosch asked VW to provide legal protection while the emissions cheating software was in development eight years ago. Despite VW’s reported refusal to indemnify Bosch, Bosch continued with the production of this defeat device.

Claims regarding Bosch’s involvement as a “knowing and active participant” in the VW scandal were filed in an amended complaint on September 2nd in U.S. District Court in San Francisco. The revised consumer fraud lawsuit now includes allegations relating to Bosch’s development and concealment of the “defeat device” (code name akustikfunktion) software which allowed vehicles to turn off certain critical functions while in test mode.

Volkswagen publicly admitted in 2015 that it had rigged emissions production in the diesel engines of approximately 11 million vehicles worldwide. More than 500 federal lawsuits were filed against the German auto manufacturer and consolidated into a single action in February of 2016. VW has already agreed to a $16.5 billion settlement to compensate owners of 475,000 2.0-liter diesel vehicles.

As reported by Bloomberg, “‘Plaintiffs do not have a full record of what unfolded in response to Bosch’s June 2, 2008 letter… However, it is indisputable that Bosch continued to develop and sell to Volkswagen hundreds of thousands of the defeat devices for U.S. vehicles’ even after it acknowledged in writing that the use of software as a ‘defeat device’ was illegal in the U.S., according to the filing.”
