Currently reading: US lawyers target Bosch in dieselgate case
Alongside Volkswagen, Bosch is said to have been a “knowing and active participant” in the scheme to dodge emissions controls

The German automotive supplier Bosch worked “hand-in-glove” with Volkswagen in the dieselgate emissions scandal, according to court papers filed in the USA.

Lawyers for owners of affected vehicles in the States have filed papers with the US District Court in San Francisco, which allege that Bosch was a “knowing and active participant” in the scheme to dodge emissions controls. Bosch supplied the ECU (engine control unit) that VW programmed to recognise when an emissions test was taking place.

“Bosch played a crucial role in the fraudulent enterprise, and profited handsomely from it,” state the papers from law firm Lieff Cabraser Heimann & Bernstein. “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.” 

Bosch has previously said it is not responsible for how a manufacturer integrates its components into vehicles.

The allegations refer to information from confidential documents supplied by Volkswagen, the details of which remain largely out of the public domain. However, they include records of communications between Bosch, VW and US regulators. The court filing states that one 2011 email to the California Air Resources Board shows “Bosch’s deep understanding of what regulators allowed and would not allow, and what Bosch did to help VW obtain approval”.

Bosch is one of the world’s largest automotive suppliers to car manufacturers. It has previously said that it will cooperate fully with investigations and has set aside 650 million Euros (£560 million) for legal expenses.

Autocar has contacted Bosch UK for comment and will update this article accordingly.

The dieselgate scandal, which broke in September last year, centres around Volkswagen’s deliberate cheating of emissions testing systems in the US, which affected some 11 million vehicles worldwide. It has resulted in lawsuits and legal action in countries around the world, including Germany and South Korea.

Last month VW agreed a $15.3 billion (£11.6 billion) buyback and compensation deal with US authorities, which will result in American customers being compensated. However, no compensation is being offered in Europe.

A device that shuts down NOx control after 22 minutes running when the test lasts 20 minutes. How about a device that shuts down NOx control below test temperatures. Both sound like very convenient software features to me and both are examples of systems fitted by two rival manufacturers. There are other examples, VW were certainly not alone.

There's no doubt

There's no doubt that VW were very silly indeed to pull this stunt in a place like America with their crazy pollution laws and culture for compensation - they burn petrol for fun out there by the way.

All manufacturers have some kind of dodge - as I said before, you cannot change the laws of Chemistry.

Does adblue assist the chemistry re NOx reduction?

All sleaze leads to VW

Bosch is involved in the Volkswagen's multi billion pound diesel scam does not surprise. Bosch - correct me if I'm wrong - makes similar parts for other car makers too but they don't cheat. Bosch made cheat parts / software for only Volkswagen.

Thought you would poke your head up on this one. All manufacturers are up to something of some description - you can't change the laws of Chemistry.
