The automaker is also conducting its own, internal investigation, but the company isn't releasing those results, yet. It has allegedly responded by suspending over 10 employees, including three top engineers. There has been reportedly no actual evidence found against this trio of men.
In addition to the work of German prosecutors, many US investigators are looking into VW's actions, as well. The West Virginia Attorney General is suing the company for fraud, and there are pending class-action lawsuits. In written testimony for a Congressional hearing, Michael Horn, President and CEO of VW Group of America, said he first learned of the emissions noncompliance when the West Virginia University study was published in the spring of 2014.
A recall on the affected Volkswagens isn't expected to begin until at least January, according to CEO Matthias Müller, and it could be later for some models. The costs to fix them all and deal with potential fines means that VW must delay some projects to save money. Put another way, VW will be dealing with the repercussions of this scandal for years.
