VW was the _first_ company selling diesel powered passenger vehicles to be caught lying. Opel/GM, Chrysler, Nissan, Jeep, Renault, Peugeot, Mercedes-Benz, BMW, Audi, and Porsche were all later caught somehow skirting diesel emissions testing. Basically all large truck manufacturers did it too.
Clean diesel is a myth, it never was a thing and the only reason anyone thought it was was because the entire auto industry was lying to regulators and customers for decades.
