DPF OFF Siemens PPD 1.2 VW 2.0TDi PD 125Kw(my solution)

Hi colleagues,
I've just made some kind of solution that turns off DPF/REGEN/POST in wv passat 2.0tdi PD 125kw, controlled by Siemens ppd1.2 ECU
Before you begin, you must reset all the dpf values using VCDS/VAS or other diagnostic tool that has such functions.if you won't do it you will probably have the dpf sign on the dash, although the car will be running fine, and you won't get limp mode, or check engine light, but the annoying dpf light will still shine on the dash.
So tell the ECU that you installed the new dpf, and then try this solution.it worked for me.all the info how to reset dpf values is in rossitech site, so everyone can find it there..
So try and enjoy, or say your critics, or give a better solution..
This isn't one switch solution, so if you have one please share, we can learn new things from each other.
I attach my original and DPF_OFF files.

P.S.Before you start programing it is strongly recommended that you back up your ECU orriginal soft using BDM, in case something goes wrong and you break your ECU
You do not have permissions to view the files yet. You have to be registered and you have to make at least 3 quality / unique posts.

Edit:
There is no real need to do the "renewal" of dpf via vcds or others, after you modify your soft in the way above and write it down to your car's ecu, the dpf light shuts down permanently after about 150-200km..

@pauliusj: how does the car behave after almost 7 years since the DPF OFF operation?
