There is no reason why a couple of engineers would do this without instructions from management simply because the engineers would not stand to gain anything by doing so without the knowledge of management.
The more serious issue here is not that of the credibility of governments. Many governments set much spite by their actions to reduce the harm done to the environment by motor vehicles, and yet here we have millions of vehicles which are doing much more harm to the environment than that are allowed to about which the governments involved appear to be doing nothing. What they seem to be concentrating on deciding who at VAG knew this was happening rather than doing something about it.
