Well, below a snippet from a log when the van was almost brand new - at 1500 miles since factory. Can't confirm the full load but probably almost there as the engine was guzzling 49.4 litres/hour at the moment (the value is updated by ECU only once per second thus repeating the same number in the log).

In the thread below a few DPF readings - as a side product of the EGR flow test - a kind of "standardised" way to produce comparable results.
So it seems - inevitable P0401.
Well, visited a VW garage to be tested - the van had accumulated 30 events in ECU's memory since July 2021 (since 20 months now). Eventually managed turn on the emission light at event number 31 - thus had a priviledge to have EGR flow tested. The result - pending - the ODIS went to an unending loop without a concluding result.
Meanwhile, I think I have reproduced the EGR flow test using VCDS. However, I don't have any reference value to estimate the degree of EGR cooler blockage. Neither did ODIS tell the reference value (should have told but the computer...
