@REH17 I see. Thank you for your reply. Do you think the problem could have been solved without the ECU rollback? So simply substituting the sensor and adapting it? I am asking as I don't know anyone who can do a rollback.

@REH17 can you confirm that there was no "DPF sensor alarm" in the ECU? So the sensor was faulty but it did not trigger alarm?

@REH17 the car has 130.000km but DPF was completely cleaned and washed last week, before getting the car back. It has 2 of those pressure sensor, and I got one changed 6months ago. I got a non original one from a car fixer, who did not adapt the new sensor either. I'll go to VW asap and perhaps ask to blow on the sensor pipes as well.

@REH17 I am living this nightmare since I bought the car one year ago, 16.000 km. Constant regenerations. I just got the car back as the warranty had to replace the engine with a new engine (crazy amount of money which I did not spend), but the issue is not solved. Incredible. Of course the sensors are still the old ones.

Thank you very much. I'm from Italy, so impossible to get there (or I will get hundreds of regenerations). I indeed can buy the new sensor from VW but as you said it required adaptation, though I heard that these new sensors can autoadapt. I'm thinking to bring the car to VW center again. Last time I did, they did a check, but in my opinion they simply scanned for faulty codes in the car memory, instead of looking at real data. What's your suggestion, buy a new original sensor from VW and mount it by myself or ask everything to VW so they adapt it?

Hi @REH17I need your help. I bought a second hand VW golf, 1.6 TDi 2015. Though the engine is different, I have a serious problem with DPF, as in my case it does active regenerations every 30km. In the images below you can see that the calculated soot mass suddently jumps from 3.5g to 24g, triggering the active regen. This thing is driving me crazy. Can you please explain how you solved the problem? From what I understood, changing the sensors did not solve the issue, but rather rolling the ECU software back to the factory did solve everything. In my case the car should not be affected by dieselgate recall but I experience this serious issue.
