May 2014 There was a line up to the problem. It was not sudden. There was time to fix the problem without shortcuts (1 year). Before the problem got out of hand (involvement of authorities). Big mistake N#1 (unintentionally or intentionally): Volkswagen tells regulators that the differences amount to technical issues and "unexpected" test conditions. First try to cover up or the start of workarounds? Protective statement. Recall in December 2014. Because the problem couldn't be fixed? The intention to “doctor” could also have been started here. May 2015 next governmental involvement. Second chance to make things right i.e. coming forward or disclose voluntarily. July 2015 point of no return. Third chance for a coming out or getting a handle on the problem. September 2015 problem total out of control on all levels; politically, technically, environmentally, reputation wise.
