Hi,
I have problem with DPF off in Mercedes W169 A180CDI (109PS) from 2005 y.
I read EDC16C31 ecu without problem by KESS but when i switch DPF OFF by Swiftec i have new DTC and CHECK ENGINE.
Before read ecu i checked it by WoW and got this DTC:
from EOBD: P2002 - The efficiency of the particulate filter below the threshold value
from 640.940: 2251 Monitoring the air flow through the particle filter - air mass too low (this dtc was without P prefix).
After writting file with DPF OFF i got this:
from EOBD: P1402 - WoW didnt recognize it
from 640.940: 2251 Differential pressure sensor - error of reliability of indications (this dtc was without P prefix).
After dpf off mode car stays in LIMP MODE (i suppose by P1402).
Before, any problem with LIMP MODE (car had good power, only smokes).
Removing dtc (P1402) from dtc table unfortunately does not help
Do you have some experience with this car and have confirmed solution ?
