Has anyone heard of the likely issues of having a VW modified to overcome the Dieselgate effect?
I'm assuming there would be either a reduction in performance or economy, or more likely both. If so, most owners won't have it done. Is it possible there will be some way of adding a test for in into the MOT?
If it's optional, why would you have your car modified? There would be no gain to you, and unmodified cars may well be worth more on the second-hand market.
