Hi all.
What is a normal soot level in the DPF? How many grams before I need to start worrying? Having some issues with code error p0544 which could be related to a blocked DPF (engine check light came up as well). When plugged the computer to OBD it is showing aroung 8g and does not want to go down while driving for about 1h at 70mph on 4th gear. So do not know if its a normal level or the regen system does not work.
Thanks
