Germany's car regulators have asked Volkswagen AG to provide a plan by October 7 for if and when its vehicles will meet national emissions requirements, after the company admitted cheating on US air-pollution tests.
The Federal Motor Transport Authority sent a letter to Volkswagen requesting a "binding" programme and schedule for a technical solution, transport minister Alexander Dobrindt said Sunday in an e-mail.
Volkswagen will present a plan in the coming days for how it will fix its affected vehicles and will notify customers and relevant authorities, Peter Thul, a company spokesman, said by phone. Bild reported earlier about the letter.
Volkswagen may have known for years about the implications of software at the centre of the test-cheating scandal, newspapers reported. Robert Bosch GmbH warned Volkswagen in 2007 that its planned use of the software is illegal, according to Bild. A Volkswagen employee did the same in 2011, Frankfurter Allgemeine Zeitung reported.
Volkswagen is investigating and will present its findings as soon as they're available, Thul said, declining to elaborate.
