Hello, I have the following problem. The car jumped into safe mode after connecting to the computer error P2002 low efficiency of the DPF filter. I must point out that after turning off the car, the error disappears. The error popped up only when overtaking the car, e.g. longer driving above 3,000 revolutions.
I decided to clean the filter in a professional machine, they give a 2-year warranty. After cleaning, the car regained power and everything seemed fine. As a precaution, after a more aggressive ride, I connected the computer again and again the P2002 error. This time, without emergency mode, after cleaning, I have driven maybe 500 km. The service cleared all settings, i.e. the amount of ash, soot. I don't know what the problem could be. Theoretically, it is a simple system: filter, temperature sensor, differential pressure sensor. What could be the symptoms of a damaged pressure sensor? If the filter were still clogged, shouldn't the error pop up all the time?
