While they company has yet to admit to any wrong doing, the CEO has now issued a formal apology and said the automaker will cooperate fully with any and all investigations. It's issued a stop-sale on all new and used TDI vehicles until further notice. VW's currently in talks with the EPA and the California Air Resources Board in regards to these allegations. It's also ordered an external investigation of its own into the matter. Whether criminal charges will be filed is yet to be seen.
