Problem Fap Polo 1.6 tdi p200200

[thekid]

hi all, I have a polo 1.6 tdi with an error p2002000 (limit efficiency filtroantipolvere low)

The error is permanent and cannot be cancelled. The ****llo of soot in the filter is below the maximum, however, the error does not clear.
I assume, therefore, that both a sensor and mange.
The pressure differential has already been changed without result.

Anyone have any idea what this sensor is going to see????

Thanks

try to see the working voltages of the sensor differential pressure it may be that you damaged the electrical part of the sensor itself sends a signal to fake the ecu..

hello note that changing the sensor the new one should be appropriate with the diagnosis
