Another set of logs. For the moment, the error hasnt come back...
I really hope that was not the issue as it is going to be very complicated... apart from loosing the remap and the money...
I guess what they will say: We have done this remap to hundreds of this engines and there hasnt been...
...it's very simple to increase the power/torque but to keep the emissions down is the challenging part.
I'm wondering what they would say about P20EE fault re their remap? Would they offer to put the OEM software back in the engine - to eliminate the remap causing the excessive NOx emissions...
Hi mmi
Thanks for such detailed analysis
So... with that context, that data is from a van where this system was not optimised yet (old software)
This really bothers me, that means adblue system is trying to compensate this high amount of NOx particulates and the fault comes up when adblue is...
Food for thought...
For comparison a recording from a T6 (150kW/204PS) without the software update - thus prone to P20EE fault. The recording was a long one - 2h18mins.
The load conditions seem to be reasonably similar to yours, see average speeds.
Based on these two recordings (just...
that makes 100% sense, so, with that paremeter, we have some kind of idea what is going on with the ad blue injectot but not a fact, understood. It is a pitty that sensor does not exist to provide an accurate measurement.
No need to thank me, just trying to be helpful sharing my data/experience...
...AdBlue flow.
Thank you very for doing and sharing the measurements!
Well, a kind of normal - I have logged quite a few (some 30+ incidents) P20EE faults without ever seeing MIL light. My feeling is that the "timeout" is somewhere in range 300-500 km - if the active fault doesn't reoccur in...
Thank you very much. That's indeed interesting. Is your van's clock in the dash panel in correct time (or actually same time as your computer)? Just trying to syncronize the log and the fault time/Instrument. Actually based on engine rpm and speed - the times seem to match.
Interestingly the...
...drive, i had the NOx error, luckily this did not turn on the MIL light, find below
1 Fault Found
31103 - SCR NOx Catalyst Bank 1
P20EE 00 [101] - Efficiency too Low
Not Confirmed - Tested Since Memory Clear
Freeze Frame
Fault Status...
...had a Carista hour! I had these faults and reset them. When I am not a lockdown self isolating w****r from my trip I'll take it for a run!
P20EE, 31103, 03303, 01044.02256
I suspect some of these were from the Tow bar fit in July.
I saw my soot level at 12.9 somewhere but damned if i can...
The faults do NOT indicate NOx sensor fault. Can you tell what software you have now - it would have been a few lines above the fault codes in the printout.
Some more:

...for my appointment at the garage, but the light is still on.
Garage now diagnose:
2 fault codes stored -
31103 - SCR NOx Catalyst Bank 1
P20EE 00 [039] - Efficiency too Low
and
33262 - Reductant System Performance Bank 1
P204F 00 [096] - Malfunction
Garage now advises:

...the time and mileage are correct in the logs.
Just an observation - in several fault logs there seems to be a correlation between the fault P20EE triggering and either high speed or high engine load (in the log below normed load value). All my faults (25+) were logged at speed above 85 km/h...
hello,
mine is a 102
software is 6163
VW just replaced glow plugs (cylindre 3)
P20EE and P204F come back
restart warning in 1000 km too,Adblue level is well.
Thank you. No need for VIN's last digits.
31103 is just VW's own code for P20EE, thus only 1 fault there. Anyways, there is an engine software update (version 6166) available for your CXHA engine. The update should cure false alarms of this fault - among other things. The trick is to inject some...
...know nothing about mechanical stuff so it worried me all the way home and I plugged Carista in, it showed two engine / exhaust related faults - P20EE and 31103 (along with 4 others, more of which later maybe!). FWIW Ad Blue was topped off about 600 miles ago.
I plan on calling AA Assist...
