It is now almost seven days since the VW emissions scandal broke. While it took days for momentum to build behind the story, I still find it sad that the company has so far made such little progress in identifying exactly where the 11 million potentially affected cars are, and what it means for owners of them.

To my mind, one of the first jobs VW must do in the wake of this debacle is rebuild customer trust, and I find its lack of communication with people who have bought its cars in good faith disappointing.

They must know which cars were fitted with this engine and which could potentially have the offending software as well. While I understand nobody wants to spread panic, I’d argue that the volume of queries from concerned owners arriving at Autocar and our sister brand What Car? these past few days suggests some information is better than none. It seems inconceivable that the issue won’t spread beyond the three named brands so far - AudiSkoda and VW - but Seat is strangely silent.

So far we only have confirmation of how many cars are potentially affected, not where they are. While logic suggests that any cars in Europe and the UK affected are perfectly legal, having passed the different NEDC test cycle, it would be good to hear this message loud and clear from someone within the VW Group.
