Does anyone know if it is normal, that Post Injection 2 - injects for every 3-5 kms?
If not, anyone knows what might cause it?
Best regards
Peter

What do you see exactly?
Does your engine has SCR filter? In this case, the ECU sometimes injects fuel to perform a little regeneration of SCR filter, maybe it's your case.

I do not know what a SCR filter is. It is an 2016 Audi A3 8v 2.0 TDI, 150 hp.
What i see is, that every 3,5 - 4,5 kms, the post injection 2 injects diesel.
It is between regenerations.....and all the time with 3,5 - 4,5 kms intervals.

Should be the SCR system regeneration.
SCR is a filter fo NOx reduction that requires, in some engines, little regenerations in the middle of the DPF main regeneration.
You can find more information about your engine searching for the engine code, it should be easy to understand if the SCR is present in your system.
You can also check if some engine group lets you read the NOx value, in this case you can verify is that value decreases during those short regenerations.
