Volkswagen's plan to recall 75,000 cars in California following the emissions scandal has been rejected.
Authorities in the state have said the German carmaker's proposal failed to explain how it would track down affected cars or limit emissions in future.
The California Air Resources Board has said that the recall plan was “unacceptable” and did not adequately identify the affected vehicles.
The state agency also issued a formal notice of violation against the car maker.
Volkswagen's chief executive is in Washington for talks today.
