OREANDA-NEWS. March 15, 2016. One of the two regulatory bodies overseeing Volkswagen's diesel debacle is the California Air Resources Board. It's responsible for verifying and signing off on any fix for VW's beleaguered 2.0 TDI engines, and it's already rejected one solution outright. Now it appears that CARB is wising up to the reality that there might never be a light at the end of the tunnel.

As part of a series of never-ending hearings surrounding Volkswagen and its misdeeds, a member of CARB's enforcement division laid it all on the table: "Unfortunately, [fixing vehicles and returning them to their certified configuration] may not be possible," CARB's Todd Sax said, according to a Reuters report.

"We will have to decide what the best approach is to dealing with these vehicles, and one of the options potentially would be to accept something less than a full fix," Sax continued.
