Bosch faces class action suit in VW emissions scandal

A class action lawsuit has been filed in the US against Robert Bosch GmbH, accusing the German auto parts supplier of conspiring with automobile giant Volkswagen to evade diesel emission standards in at least 11 million vehicles worldwide, agency reports said.

The lawsuit was filed late on Monday in the US district court in Detroit, Michigan. It names Bosch – the world's largest auto supplier – along with VW, former VW chief executive officer Martin Winterkorn, and VW America chief Michael Horn.

“Volkswagen's fraudulent scheme was facilitated and aided and abetted by defendant Bosch, which created the software used in Volkswagen's defeat device,” said the 56-page lawsuit, which accuses the parties of violating civil racketeering laws and consumer fraud.

In September, Volkswagen’s EA 189 diesel engine was found by the US Environment Protection Agency to have been fitted with a ‘defeat device’ — a software that modified its performance when it sensed being run in ‘test condition’ by monitoring speed, engine operation, and even steering-wheel position.

Last month, news reports had suggested that the US justice department was examining whether Bosch knew of or participated in Volkswagen's efforts to circumvent US diesel emissions tests.

Bosch built key components in the engine used in six Volkswagen models and one Audi model that the automaker has admitted to rigging to defeat emissions tests.
