Last week TüV and AU were due. Although my car is fully in fire, so absolutely no defects, I did not get an AU!! The values were very high. Then again all filters were changed, again checked for errors… etc. Monday morning the examiner was again there, with the same device !, and what should I tell you … the values have risen immensely … failed!! For 300€… What should I do now? First refuel the expensive diesel …have 4 weeks time a If the examiners come back with the new equipment (according to the law probably from 1.7.2023), I probably have no chance. Do you have a tip? It will soon go other, with Euro6 cars, also like that.. LG Hexlein
