I have a 2014 Q7 with the CNRB 3.0TDI with EDC17CP44, I need to delete the DPF, SCR, Adblue, and I need to disconnect the sensors for these (there was underbody damage and I can not leave the original pipes, I will replace with a straight pipe).

I have researched how to locate the DPF switch but have not figured this out yet.

I am aware of these "ADS" and "Davinci" solutions which delete DTC only but I think I need actual switch OFF + DTC delete so that there are no future problems and I can disconnect the DPF/SCR/Adblue parts.

I have posted my file, this ECU is marked 4L2-910-401-A / 4L0-907-401-E HW:23.

This is a north american car so it had the "fix".

Can anyone help me with pointers or files to find the DPF switch?  Is it correct that there should be no re-mapping needed for EDC17CP44 w/CNRB and I should need only Switch OFF + DTC delete for disconnecting sensors and removing DPF+SCR pipes?  I have attached JTAG reads from KTAG.

Best regards to all

Hello thank you can you tell me is this file DTC delete only or is there a DPF switch also OFF/any remap?  I am reading other posts about CNRB and DTC delete ONLY not being enough for this car?  I really want to learn and understand this so I can fully remap the car later after I drive it for some time.

Hello Jurebv I really appreciate your effort, unfortunately I really need to disconnect all the wires that go to the sensors on the DPF and SCR.  There was underbody damage on this car (I was able to buy it for very cheap!) and I did cut/splice the wires back together but it is a mess under there and I want to be able to eliminate all of the sensors since the DPF and SCR are smashed on the bottom and I must remove them and replace them with pipe.  Regardless I appreciate your effort though, thank you!!!

just because i write no need to disconnect doesnt mean you cannot disconnect , you can disconnect anything you want , file will work
