In this picture the yellow DPF highlight address has been changed to a RED vertical bar.Īs you can see, the DPF switch location is not obvious when viewing in 2D mode. This is the TEXT picture above shown in 2D view. The correct DPF switch position is highlighted in YELLOW on the above picture.Ĭhanging the value 00001 to 00000 will switch off all DPF functions *įor those that like 2D view. NOTE: If the 04081, 00015 search doesn’t help. In many files the DPF switch 00001 is followed by 02800 so the DPF switch is the second 00001.Īnother clue is that the DPF switch 00001 is usually close and to the left of the sequence 32768, 32767. In the example you can see that this occurs twice. In 16 bit decimal view the DPF switch is 00001. It is important to view this whole row because the DPF switch is not always at exactly the same address in all ECU files. Make sure you have a least 14 columns in your view and move the selected two addresses to the start row as shown above. This sequence usually only occurs once in a file so you should be in the correct 4. The addresses for 0405 will be highlighted. Enter 4081, 00015 Click right arrow button or Enter button.Open ‘Search’ and then search for decimal byte sequence (decimal tab).The file below has been opened in 16 bit, decimal (255), LoHi view. With the hardware sorted you are ready to modify the ECU file.Īs usual the information here is based on using Winols to examine and modify your file.
Dpf off install#
Refit and try the forced DO NOT INSTALL A DPF OFF FILE BEFORE THE HARDWARE HAS BEEN SORTED You may have to remove the DPF and soak it in something like alloy wheel cleaner for a day or so.
What if forced regeneration doesn’t work?
