Re: Not all need to be recalled.
If you have an affected diesel VW - you could make the case that it is not fit for purpose or that it was sold under false pretences and just get your money back. What will VW do with a 3 year old car no-one wants. What about all the inner-city located cars that have low/no-TAX concessions due to their stated low-emissions? Where are you going to park now? After the SW *upgrade* has killed performance who will want a gutless VW diesel?
Expect lots of VW diesels on eBay for very little money real soon.
Perhaps some enterprising after-market *downgrades* to restore the performance lost by the forthcoming emissions *upgrade*.
