SAN FRANCISCO — A federal judge is set to get an update on ongoing settlement talks in the Volkswagen emissions cheating scandal after announcing a tentative deal last month for nearly half a million polluting Volkswagens in the U.S.

Attorneys for Volkswagen and Volkswagen owners filed an agenda for today’s hearing before Senior U.S. District Court Judge Charles Breyer that includes a report on discussions over roughly 482,000 Volkswagens with 2-liter, four-cylinder diesel engines.

The agenda does not indicate whether the parties have reached agreement on more terms that will be disclosed in court. Breyer has put the attorneys under a gag order that prevents them from discussing the settlement talks.

He announced a tentative deal last month that would give the owners of nearly half a million Volkswagens the option of selling their vehicles back to the company or getting them repaired. But many questions remain unanswered, including how much money owners can expect in a buyback and how much additional compensation beyond repairs and buybacks they’ll receive.
