regeneration is between 20 and 40 km

Post by Fito1242 » Wed Jun 09, 2021 1:43 pm

I have continuous regeneration between 20 and 40km in 2015 skoda superb 2.0 TDI 150cv.
They have cleaned the filter twice and the last one also the EGR cooler, previously the pressure sensors.
We do not know what the problem is, I would appreciate your help.

Remotely is very difficult to help you. The cleaning was done by official service? Have you checked the ECU error logs?

the ecu does not give any error, no message has ever appeared about the filter.
the cleaning has been done by a specialized workshop, they have disassembled the filter and put it in a machine, I think it is ultrasound.
I would upload screenshots of the program, but I don't know how to do it.

I know that after a filter cleaning, including a full oil ash residue removing, it's recommended to reset all learned data with a specific command present in the official software ODIS, or also in VCDS.
Do you know if they did it?

Have you logged some values to understand if there is some parameter out of range? This behavior usually correspond to some missing or implausible data received by the ECU that make it going in emergency mode performing frequent regeneration to avoid risk of filter fire.

I don't know if they have done something with the program, the first time a regeneration with the computer.
I have the vcd program, if you tell me what and how I could do it, to discard.
Thank you

I'm sorry, I never experimented that procedure, I only know it exists.
If you don't have any other advice, maybe try to go deep in this possibility..

What strikes me a lot is that the pressure differential has barely dropped, it is idling at 15, and the nox has dropped from more than 2 thousand to more than 1 thousand

Have you logged some trip with the app? If you have the log file I can check the values.
