I disagree. I think this shows that if you break the rules with impunity, there is a significant risk that you will be caught. The Panama papers is another great example of this. Overall this is likely to have a net negative impact for VW.
The Panama papers don't, in fact, show that a lot of rich people are scamming tax. Many of those people are likely paying capital gains tax in their countries when they sell their assets (as Cameron did). The few that are evading tax will likely get caught.
As I see it, the majority of the really rich aren't corrupt (at least in the USA/Canada). Other countries maybe, but those countries tend to be corrupt to begin with.
