P1206 error (dpf)

The engin flash came up and I check the code which was P1206
The car drive fine, no power down
2 days later the light went off and the car still drive fine but in the ecu is still the error P1206
I check the dpf and a few days ago it was filled for 76% and today it was 102%
Today I did a forced regeneration and now it is 80% again but I did not remove the error.
It is a Doblo from 2007 with a 1.9MJT engine

My questions :


Does anyone have some advice ?

Should I remove the error ?
I ask that because it drive fine without power lost and I am afraid when I remove the error it come back again with power lost.


Can I drive back home which is around 1350km ?

you cant just remove it you have to delete it in the ecu too, or ecu will keep chucking fuel down the exhaust and you will have clouds of blue smoke coming out the back.

Re: P1206 error (dpf)

I know and they update the ECU.
I donīt know about the smoke but they told me that it is still confirm the rules so I donīt worry about that.
This DPF gave me so much problems that I consider to sell the car.
The car by it self drive very good so we made that decision.
And if it give bleu smoke backside .... I donīt care as long as it keep driving like it should and I donīt get problems with the inspection, which they confirm : I donīt get.

Re: P1206 error (dpf)

It is done, they renew the ECU software and delete the EGR - DPF and sensors
They also did a tune-up and my Doblo drive great now, no smoke and no error lights and because of the tune-up I have much more power, drive much better and now I hope it also take less diesel but that take some km befor I know that.
Thankīs for all advices and help
