Volkswagen's commercial vehicles and cars from its Spanish unit SEAT are among the 11 million fitted with a diesel engine that can cheat on emissions tests, the company said Tuesday.
Volkswagen AG has admitted using a piece of engine software to cheat on diesel car emissions tests in the U.S., where authorities say there are 482,000 such cars. The company says that up to 11 million vehicles worldwide were fitted with the engine in question.
Not all of the 11 million vehicles, however, would have had the software activated, according to new CEO Matthias Mueller.
Details have emerged gradually of how many were made by which VW division. Guenther Scherelis, a spokesman for the commercial vehicles unit - which makes vans and pickups - on Tuesday confirmed that 1.8 million of its vehicles were affected. He didn't give further details.
Spanish subsidiary SEAT said it fitted 700,000 vehicles with the EA 189 diesel engines in which Volkswagen has said there are "discrepancies."
SEAT said the cars were sold worldwide and it was seeking to determine how many were sold in each market.
Also fitted with the suspect software were 5 million VW brand cars, 2.1 million Audis and 1.2 million Skodas.
SEAT and Volkswagen-Audi Spain on Tuesday ordered a suspension of sales of all SEAT, Volkswagen, Audi, Skoda and Volkswagen commercial vehicles with the EA 189 diesel engine. It said this decision would affect 3,320 vehicles currently in stock.
In a speech to VW managers Monday evening, newly appointed CEO Mueller said that the offending software was activated only in part of the cars fitted with the engine, so "we expect that the number of vehicles actually affected will be smaller," according to extracts released by the company.
He said customers will be informed in the coming days that their vehicles need work and authorities will be presented with "technical solutions" in October.
Mueller said that, alongside the company's internal probe, Volkswagen's supervisory board has commissioned an external investigation by U.S. law firm Jones Day, and "that will start very quickly."
"A long road and a lot of hard work lie ahead of us," he said.
The German government last week set up a commission of inquiry on the scandal. Transport Ministry spokesman Martin Susteck said that the panel is in contact with the U.S. Environmental Protection Agency.
In Brussels, European Union Industry Commissioner Elzbieta Bienkowska was scheduled to meet Tuesday with Volkswagen brand chief Herbert Diess.
"We expect Volkswagen to explain the situation," said EU spokesman Ricardo Cardoso. "The Commission wants facts and wants to get to the bottom of this."
