Hello,

This might have been asked a lot of times but I need a little bit feedback if possible please.
History: Skoda Octavia 1.6L CR TDI, new injectors and new EGR. After replacement of those parts engine light came on with the P2002 code after some driving. The first time I managed to clean it by service regeneration. The measured soot was 66g and it was close to the 70g limit. After regen it fell down to 6g and management light turned off. Decided just in case to use one of these DPF cleaners and fuel additive for DPF cleaninbg as well. After a few days the management light came on again after a long trip, so something is not right. I have looked into the values but the soot was a negative number. This does not seem right. Did pressure sensor got damaged or something? What do you think? The car does many frequent regenerations
Planning to inspect the sensors around the DPF this weekend
Thanks in advance for any tip

Full scan and some data attached
