A class-action suit representing vehicle owners claimed Bosch was a 'knowing and active participant' in the emissions cheat.

Volkswagen Group has negotiated a $2.1 billion CAD (~$1.6 billion USD) settlement with Canada regulators, while supplier Bosch reportedly faces a separate $300 million payout in a civil lawsuit filed by vehicle owners.The agreement puts a price tag on a buyback and repair program for more than 100,000 vehicles sold in Canada with the diesel emissions 'defeat device.' An equivalent settlement with US authorities included a commitment of more than $10 billion USD to buy back or fix nearly a half million cars.

"Volkswagen's primary goal has always been to ensure our Canadian customers are treated fairly, and we believe that this proposed resolution achieves this aim," a VW spokesperson said in a statement to Reuters.

The alleged Bosch settlement, also reported by Reuters, centers around a lawsuit that accused the company of playing an active role in developing the system to cheat emissions tests.

"It is inconceivable that Bosch did not know that the software it was responsible for defining, developing, testing, maintaining and delivering contained an illegal defeat device," attorneys argued.

Bosch set aside around $750 million to cover potential costs of government enforcement and civil litigation.
