Volvo D13 Regen Issues

William Diagnostician California Posted   Latest   Edited  

Do you have volvo ptt software, if you do what are the exhaust temp on all three temp sensors. Does this happen when the hydocarbon doser is dosing or before it reaches temp to start regening

William I’m a little confused after reading your post what you’re asking. Many times a regen is for the DPF (diesel particulate filter) and the fuel for that operation is from the engine’s fuel injection system. The “doser” usually is for the 34 percent urea (DEF) diesel exhaust fluid from the DEF reservoir. Do you have codes? What isn’t the emission system doing right?
