Volkswagen may not be able to reach an agreement with US Environmental authorities on an emissions fix by the April 21 deadline set by a US Federal judge.
US Environmental Protection Agency Administrator Gina McCarthy told reporters that the two sides were in "really robust" ongoing talks but said she did not know if they would agree to a deal by the April 21 deadline set by U.S. District Judge Charles Breyer.
It is still not sure whether the US government will accept a partial fix of the 580,000 polluting vehicles or if it would insist that Volkswagen offer to buy them all back.
Federal Judge Charles Breyer had set the April 21 deadline after the two sides failed to reach an agreement in March.
The judge has stated that if the government and VW would not reach an agreement by April 21, he would consider holding a trial in the summer.
