Today, Friday 18 March, is six months to the day that the VW Group emissions scandal broke. In time, studies will fully map out how and why the firm chose to cheat, how it was caught and how effective its response was, but now seems as good a time as any to pause and take stock of the revelations that have emerged so far and the hurdles ahead.

What’s abundantly clear is that the scandal has barely begun. In the past month alone we’ve had the revelation that the VW Group’s management was aware of the problems as long ago as May 2014. There have been accusations that the firm believed it could buy its way out of trouble, via a large but not humiliating fine, right up until the last minute. There are suggestions that VW Group engineers were refining the cheat codes long after the firm was accused of using them. An employee has claimed that he was fired for whistleblowing. There are emerging stories that the proposed fixes are neither as effective nor coming on stream as quickly as claimed. And we’re six days from the company needing to agree a solution with US authorities, with absolutely no sign of a solution being in place.

The scandal isn't over yet

Make no mistake, the snowball of bad news that enveloped the company on 18 September is still gathering momentum; if you think the VW scandal is old news, that’s only because you’ve become immunised to it by repeated exposure to more shocking revelations, and because the VW Group PR machine has become marginally more adept at handling the fallout than it was during the calamitous early weeks.

Perhaps the biggest challenge on the horizon comes in just over a month’s time, when the VW Group is promising to publish the report of its appointed independent investigators, Jones Day, into how the scandal was allowed to happen, as well as the VW brand’s 2015 financial results.

To date, VW’s senior management has deflected probing questions by saying they must allow the investigators to do their jobs unhindered; at that point, they must not be allowed to hide as they have at recent public appearances, and the report itself must be scrutinised in the finest detail. The pie-in-the-sky distraction of launching a ground-breaking electric car by 2025 that dominated their Geneva motor show thoughts must not be allowed to be pedalled as a smokescreen again.

Even then, the story is far from over. A VW Group-appointed investigation can never be considered conclusive, and while it may shed more light on some of the more hard-to-believe claims made so far, chiefly that the cheat was the work of a tiny number of rogue engineers, there’s no doubt that higher-level legal actions around the world will seek to uncover more. Not even the well-oiled machine of one of the world’s largest companies, backed no doubt by numerous well-paid crisis advisors, will be able to stem the tide when the US legal system swings into action. My only hope is that they seek to find answers as ardently as they appear to be trying to break records for corporate fines.
