...is still out of date - dealer requiring money to run diagnostics has put me off going to them
Obeleven and adblue range indication seems to.indicate that adblues going through the system
My fault was only intermittent p20ee no other codes So discounted egr straight away from faults thankfully
Having pretty much the same issue with mine.
Intermittent P20EE fault on longer runs.
Had Nox sensor replaced but still the same.
Not sure on my software version, I’ll have to check it.
...in, it came back two faults both of which they reckon would be sorted by the update:
P204F (Pending) - Reductant System Performance Bank 1
P20EE (Pending) (Confirmed) - SCR NOx Catalyst Efficiency Below Threshold Bank 1
Anyway, it's done now and I can only take their word that things are...
Did you clear the fault memory between the runs? Just to get fresh start for each run - as this fault is based on NOx emission accumulation over time.
Did you check fault memory after 90 mile run - to see if there the fault was already in pending state?
Did you read the fault memory without...
...different road types
So far 1 run of 90 miles flattish roads gave no faults
1 run of 145miles mixed speeds including hills gave intermittent p20ee fault and eml on
More runs to be tried in the next 2 weeks runs all to be recorded
Best scenario we get an active fault
Worst case we gather data...
Yes your right p20ee my phone auto spelt it
Only just got the van last week so unknown how long the codes have been an issue
Looking through the service documents no obvious clues
Just been out today 90 miles no eml but this just confirms its longer run issues
No obvious regen cycle during...
I guess it's actually P20EE - which is not about the sensor being faulty. It's about too high NOx levels detected.
Hmmm... any more info - has it ever worked without the fault?
That would fix "false alarms" but if there is an underlying real fault can't cure that - of course...
Hi peeps
Firstly what a great forum and excellent knowledge base I have spent more time on here than driving the van
Thanks to the many posts on the forum my mind is at ease on the pe20ee nox sensor fault eml light co.ing on after buying obd 11 I can see this is an intermittent issue (happens...
Hi, is there any way I can find out about a software update for my T6 2018 150ps, it keeps throwing up P20EE and every now and then the adblue DEF faults and warnings, then they will go off and stay off for a while but come back up every now and then and reading on here looks like this may have...
I hope its ok If I steal thread As I got same problem with my t6
Purchase van 2 weeks ago and get error same day. As show on image was 4500ml of adblue
Then 20 miles later was much less
At this moment I'm unable to drive until next month and trying to sort it out and see what its a problem...
...on which VCDS is reporting as:
23871 - EGR System
P0401 00 [236] - Insufficient Flow
and
31103 - SCR NOx Catalyst Bank 1
P20EE 00 [100] - Efficiency too Low
I think this means the EGR needs cleaning/replacing, but having been quoted ~£900 for that, I might get a second...
Interesting, mine has "blipped" the adblue warning a couple of times but in general it was just the EML light, P20EE and P204F (31103 and 33262). I can't believe VW don't know about the issue or have a fix. The dealers do not seem interested asking the question of head office. they are like...
Xxx
thanks, he’s just cleared the codes and on startup the light is off. Thanks for all the advice, you’ve put our trip back on track! Fingers crossed they don’t come back. Thanks again!
That code pops up quite frequently when people are in France!?

If you're still with that guy get the code reset for now and monitor. It's more likely a 'software glitch' than anything serious.
Loads of threads on here about it.
Presumably your 2019 M1/passenger class, CXGB engine ECU would have been updated from the excessive NOx polluting 4147 software version to the latest 'clean' 6163 version at the factory. Your scan tool should be able to tell you the version.
...sorry for bringing this thread back to life, but I have a 2019 Transporter Shuttle BMT 102hp with 33k miles and it has just started to report this P20EE fault. The VIN starts with WV2 and is classed as M1. Would my engine be one that requires this update you speak about?
Many thanks for your...
Correct yes I had the amber emissions light present on the dash
Yeah i did wonder if that could be the case - I have a 650 mile round trip next week so going to see what it does then....could leave me stranded if the countdown starts but should see what codes are captured on the journey.
