Just so everyone else understands how our justice system works (at the Federal level anyway). The FBI does not just "decide" to arrest someone. An agent can start an investigation and want to arrest someone. But if a federal district attorney is not on board, usually no arrest will happen. 99 times out of 100, a Federal District Attorney (usually in the region where the company / person is headquartered) makes this decision and then the FBI (or other federal agency) acts, especially in major cases like this. Many times there is a working relationship. An FBI agent might call a district attorney and "shop" his case: "Hey Jim, it's agent Bob, I have a slam dunk case for you here, call me." Other times the crime is serious enough its totally obvious that everyone is going to peruse it (murder, child exploitation, major drug stuff, etc.) And other times, the District Attorney calls the agent and says "Bob, these Volkswagen people need to pay for what they have done, lets throw the book at them, start investigating." We will probably never know what happened in this Volkswagen case, but make no mistake that people inside the White House, FBI headquarters and Loretta Lynch's office all had to "thumbs up" a persecution on this level. One lowly agent doesn't make these decisions.
