hello to all.
someone can disable the error P1901 on this file?
it is a opel astra 1900 cdti 120 hp.
I think that the affected area is between 0C8534 and 0C85F2
I ran the defap, the car is perfect, do not even mention to the regeneration but I have this error in diagnosis.
I also saw on damos a switch to override the reading of differential pressure sensor, if someone saves me from doing what I do 200 tests welcome.

I've done other and never had any problems. this is the car of my father in law and decided to give it a bit of discomfort. Thank you in advance anyone give me a hand.

ori file attached

What is measured diff. pressure with ignition, idle and full load?
I mean - the sensor is good or not?
Cheers!

today control with the diagnosis the percentage of clogging of fap.
before performing the defap the machine had no abnormality.
The fap was removed only because the car really very little walking and many times the regeneration was not even completed.

a little off topic........

the usual "professors" can avoid sending PM with offers of paid service.
if the machine had been a customer would have gladly paid the file to a person I thought was capable.
since it is family car and, considering that we should put in addition to the work that I have already made ***8203;***8203;money, too, I thank anyone who wants to help me.
all those who use this wonderful forum to make money are invited to go to write PM to others.
THANK YOU

I noticed that the software behave in nearly the same way on this file.
usually these cars I have never created problems, just want to give this discomfort.
As soon as I see five minutes to fix it.
in the meantime I wanted to disable this error so go without fail.
