The California Air Resources Board (CARB) has rejected Volkswagen’s proposed diesel fix.

The state said that the German automaker’s proposed fix was not adequate or fast enough, and that it would continue its investigation in addition to talks with Volkswagen to find a reasonable fix. No immediate penalties were assessed by California regulators but it has issued a new notice that Volkswagen has violated California air quality regulations.

Volkswagen CEO Matthias Muller will be meeting with Environmental Protection Agency (EPA) chief Gina McCarthy tomorrow to discuss the diesel emissions scandal that now impacts almost 600,000 vehicles in the U.S. and up to 11-million units worldwide.

It was reported earlier that Volkswagen is pointing to German privacy laws as an excuse to not hand over emails or other communications among its executives to U.S. officials. The U.S. Justice Department has said that Volkswagen has “impeded and obstructed” regulators while providing “misleading information” during the current investigation.

It is believed that one of the proposed fixes from Volkswagen is to replace the catalytic converters on affected vehicles, although that fix would only apply to about 400,000 of the affected 600,000 vehicles, potentially leaving 200,000 for the automaker to buy back from owners.
