It’d probably need owners and prospective owners of VW’s to vote with their feet ‘en masse’ and not buy VW cars before VW take notice and listen to their customers.
If VW experienced a significant drop in sales they may take some positive action; in reality, they probably wouldn’t though.
Give it another couple of years then you will get the swimming pool in the boot too. I am working through this currently with a not so old mark 7.
