So your remap is gone? Which one was the most recent, remap or VW software update?

I presume you had to pay for the new software? What did they charge you please?

I used to get the P20EE quite regularly but after hounding VW to get the software update I haven’t had any further fault codes relating to this. That’s been over a year now. My van is a 2017 102ps 5 speed. Its be remapped to circa 150ps for well over 1.5 years now

...The others - any notes what they were? I've been tracking the Forum and this far the software update has cured the (false alarms of) faults P20EE and P204F. On mine those haven't surfaced any more - for 17 months/14000 miles now. Some more here...

Yes, exactly, thanks. I was curious about your van's engine software version because the recent software update should have eliminated fault P20EE (31103). That's the reason why I'm chasing P20EE faults around the Forum. So far no P20EE faults from new software.... "Fortunately" your engine...

Could you please share Carista "Detailed ECU info" (under Service menu)?

Hi - Having similar issues with my T6 showing the P0401 and P20EE codes on my Carista OBD. I've just bought the van which is 2 months out of warranty, but only done 12,000 miles. I've spoken to VW who said they 'may' consider fixing under goodwill if I can show them the service history. However...

...difference in how the van is behaving. Fuel consumption unchanged, no discernible difference in how the van is performing. key codes are P20EE - SCR NOx catalysts efficiency below threshold bank one, and the associated 31103. Given the lack of any impact I have elected to reset the codes...

...was an official recall - at least here in Finland. I'd expect it to be same in the UK. For N1 class (basically VIN WV1....) the update has not been classified as mandatory but will be done if faults (especially P204F, P20EE) show up. So basically the decision is left to service center :rolleyes:

That's really well explained, thank you. Had my vw software update 4 days ago after a serious of Nox EML displays. Will keep an eye on the Adblue range, read 5000 on leaving Vw.

...at all during DPF regeneration - which actually caused the NOx levels go very high - which eventually every now and then triggered fault P20EE 00 - Efficiency too Low. Among other things the updated engine now uses AdBlue also during DPF regeneration - which definitely means more used now. A...

How would I go about getting this updated? Does it have to be a VW garage/service centre?

...However, for N1 class (basically VIN WV1....) the update has not been classified as mandatory (as it was for passenger carriers) but should be done if faults (especially) P204F, P20EE show up. A related thread --> https://www.t6forum.com/threads/adblue-discussion-and-issues.8270/post-346774

...in black and white - unfortunately. For T6 (EU6) there were two main waves of updates. The latest and greatest should iron out pretty much all the wrinkles that have caused a lot of frustration and discussion also around our Forum. I'm anticipating that P20EE and P204F will finally become...

Did you note down engine software identifiers before and after the update by any chance?

I noticed EML showing half way through an 80 mile journey on 12/12/20. A Carista scan reported P20EE fault. Next day I booked it into VW for first available date, which was yesterday 19/01/21. Not impressive if anything is critical! To resolve the issue they performed software update TPI...

...The new version is 6163. Yes, this will fix the software glitch which caused elevated NOx levels in the exhaust thus eventually triggering the P20EE fault. I'd stick with VW for the update - you might even get free AdBlue refills. Although, the update is available to any garage (as was...

I had the P204 and the P20EE. the software update and recalibration of the level sensor got sorted but received numerous P20EE faults resulting in 6 trips to VW and having my van for over 50 days last year. So in order I had the software update, new nox sensor, twice they didn’t really do...

Hi all, I have fault code P20EE and after reading this thread I'm still quite confused. As far as I can see from carista: Engine Part #: 04L906056KA Component: R4 2.0l TDI Software version: 4047 My software is the older version? So would updating this stop the fault? Can any vw specialist do...
