P20EE00 & P040100

[SlothBurger]

In the last 2/3 weeks my 2019 Kombi (CXEB) is showing these faults in Carista. I've cleared them & they come back. One of the faults appears then the other. So far never both faults together.

Previously a few months ago the EGR pipe was changed because it was split but not the cooler part of EGR.

I'm seeing DPF regens about every 150 miles or less & mostly doing long journeys over 1 hour.

Feeling a rumble on idle last few months but I thought this might be the flywheel.

What further troubleshooting steps can I do myself to figure out what's the issue?

P20EE - please verify that engine controller software is up-to-date.
Please post "Detailed ECU info"-report (under Carista Service menu).

P0401 - you could run engine's self diagnostic routine to verfiy the issue

Thread '[T6_measured] 01-Engine - Built-in test for EGR'

23 Apr 2023

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...
