Hello to each other, I open up a “new” topic, because I have found nothing for the fast but please need an appropriate answer: My C4 with 150 hp diesel engine, E6, from 2015 consumes very little AdBlue. Can I conclude that my exhaust gas cleaning also has a “fraud software” or that there is another “error” annual output August 2015 to August 2016: 12,200 km, AdBlue consumption: 7 liters (~0.6 L/1000km) annual output August 2016 to August 2017: 11. 600 km, AdBlue consumption: 9 liters (~0.8 L/1000km) This is only about half of the expected consumption. On the internet you will find a real consumption of about 1.5 liters on 1000 km travel distance. My diesel consumption is about 6.4 liters/100km – that indicates the way of driving!?! What is a normal consumption of AdBlue for my vehicle? What did you do if you have determined similar values? Thank you and until then NeuBrander (now 2 years in the forum with over 100 contributions) (exact model name: C4 PIC 5 SEL BL HDI 150)
