Hello municipality, after a long time I have registered now. What should I say. My additive tank seems to be empty. Now the question of which additive should be in there torments me. Would it do it myself. These 2 stands to choose from:EOLYS 176 Additive Gen 2 or EOLYS PowerFlex Gen 3. Unfortunately I found nothing in the manual and when reading along I always came across EOLYS 176. My C30 with the first registration date 29.03.2010 probably exactly in the generation change of the additive ger The key number………. 9101/AFS……… Running 85,400 I took over the car from a city driver. I only drive long-distance highway. Maybe someone can help me here. Thanks a lot and you have a nice holiday.
