Dear experts, it is only slowly becoming for those who have a tdi with Euro 5 standard (whether cheated or not). I have a touran with the 105 hp 1.6 tdi, (built in 2012) and which I bought extra new, in order to then be able to drive it for a very long time. Now I would like to know if there are any considerations to develop retrofitting possibilities for Euro 5 diesel, in order to obtain a blue badge. That this is not trivial and that because of the injection of Heranstoff larger interventions are necessary, is clear to me. But especially with newer vehicles (theoretical) a larger investment might be worthwhile. Thanks for the one or other technically sound opinion Gysbert
