In a statement on its website issued from the company's HQ in Wolfsburg, Germany, on Friday, Herbert Diess, CEO of the Volkswagen Passenger Cars brand, said: "We are working at full speed on a technical solution that we will present to partners, to our customers and to the public as swiftly as possible.
"Our aim is to inform our customers as quickly as possible, so that their vehicles comply fully with regulations. I assure you that Volkswagen will do everything humanly possible to win back the trust of our customers, the dealerships and the public."
An internal evaluation revealed that approximately five million VW vehicles are affected worldwide. The brand is working with the certification authorities and will inform all markets worldwide how many of vehicles are affected locally.
On Friday, VW appointed Matthias Muller, the former boss of Porsche, as its new CEO. Speaking at a press conference, Muller did not reveal how many people had been suspended or who they were but said the scandal was the result of "engineers" and "technicians".
Muller replaces Martin Winterkorn, who resigned last week following revelations in the US that Volkswagen installed software in its cars to disguise emission levels.
It has since been reported across German and international media that the firm was warned about the software on multiple occasions in recent years.
