SID803

5WS40201E-T
SW9658432280
HW9655041480

Please can diasable DPF and any related DTC?
I have been searching in MPC and didnt found.
I do not want to use any sw (ads 2017 etc), i have checked ads and imho too much changes applied, and many dtcs erased.
I prefer manual solution.
In this SID803 IS ON MPC .
RIGHT??

Found this info on DKFORUM, sorry did not remember user:

You need to change the 1 to 0 to the following hex addresses in the file:

4A260 4A262 4A273 4A274 4A28B 4A28C 4A28D 4A28E 4A28F 4A2C8
4A2F2 4A2F3 4A2F5 4A2FC 4A302 4A311 4A31C 4A327 4A35C 4A7FE
4A82E 4A82F 4A855 4A856 62D8F 62DAF

The ones staring with 4 are the error codes for various DPF sensors and triggers,
we are disabling to not have DTCs if you run out of EOLYS, DPS sensor breaks and so on..
The 2 last actually tells the ECU it’s a DPF free version. If some of the addresses already are 00 leave them as they are.

In my case did not seems very logical as no adress has 01.....
Did not find any thread with a NON PASSWORDED FILE.
So please, sorry for disturb...ANYWAY

And of course really thanked beforehand anyway ANYONE.
Even if you only read it.

DPF switch in your file:
$4D4E9 - set to 0
then erase DTCs and you're done

Ok I can see now you removed the $6374E instruction
I didnt understand it

$4D4E9 - set to 0 is the switch called lc_act_pf??

ONly one is necessary on this ecu..?
I believed it were 2 switches and of course any related DTC

Thanks of course
Gonna make myself a manual solution removing only dtcs I want, and switch of course.
Hopefully I finlally understand table dtc on this ecu ( I think :)

Many many thanks everyone

is the switch called lc_act_pf??

Yes.
lc_act_pf = 0
no more regenerations

delete only DTCs related to DPF pressure and temperature sensors

you can also set $6374E = 1, but it is not necessary
