Good day, I’ve had a second-hand French diesel vehicle with SCR system for one year (January 2023). I’ve only driven 10,000 km with it since then and now with ~60,000 km I get the first notification/request for refilling the AdBlue. In ~2,000 km they want to deny me the start. I know that the vehicle also stood before my purchase at least a year since the previous owner had passed away. As I read, the AdBlue liquid is about a Jah r durable. So in the AdBlue tank of my vehicle there are now a few liters that are likely. Since I am reading in vehicle forums, I know that the AdBlue system makes my vehicle and can only be exchanged as a whole. (€ 1,000+ of pure material costs) Regardless of this, I plan to add an additive to counteract the crystallization. Thank you and thank you very much!
