...which had 3000 miles adblue range on MFD. I have done 750 miles and it has not changed. I did a scan and the following fault code came up: P20EE and P20EE00 (SCR nox catalyst efficiency below threshold) I have deleted the code and will see if it reappears. Does this sound like adblue has...

So spent the last few hours reading all these issues with P20EE codes and I now feel proper stressed, only had the van 5 weeks and done 300 miles in it and got the dreaded light today:( Is there a way I can check my software version? I haven't got access to VCDS readily and a garage used a...

There is an update available - version 6163. The update should cure a few niggles - mainly fault P20EE and sudden AdBlue range drop (to 1000 km/650 miles). A before/after comparison here...

I had a reoccurring engine light with code p0401 "egr a" flow insufficient and then an second one p20ee SCR nox catalyst efficiency below threshold bank 1. I was having no performance issues, just engine management lights. Yes, all original bits still on can, egr has been blanked, both bits...

Thank you for that, I have recently had a stage 1 remap, would this affect the remap if I had this carried out ?

...had my EGR cooler replaced as a gesture of goodwill at VW Preston. Van Is 4 years 9 months & done 23.5k. EML light and carista codes P0401, P20EE Had it flushed under warranty a couple of years ago at Manchester. Was ringing around for quotes on EGR replacement before reading this thread...

...is exactly as it was from new Started getting engine warning light in March..got a carista & these codes appeared & disappeared randomly 31103 P20EE 33262 P204F 06720 08216 08217 08338 08208 Low level adblue warning light & was in fact full, went away within 50miles Finally went into limp...

...only partial) DPF regeneration. This shortened cycle combined with highly elevated NOx levels during DPF regeneration could be a candidate for P20EE fault under certain conditions. Exact threshold TBC - highest recorded soot calculated was 10.61 grams, which ECU considered as finished DPF...

...engine cold start effects on NOx emissions - possibly addressed by ECU update (see above "Short term stats") - possibly related to infamous P20EE fault code in early days of T6. In this data the "DPF regeneration" period has been isolated from the data (different journeys than "Normal engine...

...was an official recall. For N1 class (VIN WV1....) the update was not classified as mandatory but was/will be done if faults (especially P204F, P20EE) show up. So basically the decision is left to service center. In the paperwork it was mentioned that the update might increase AdBlue...

...reagent INCORR_REAG ENG110382-ENG20516 SCR inducem system status-inducement system active active I believe they are related. P20EE just indicates too high NOx level in the exhaust, which is a consequence of poorly working NOx reduction system as a whole. Thus a guess would be either the...

...piles of junk to earn a living. I like many have experienced these issues. My van was in 6 times for a total of 52 days back in 2020 due to the P20EE code. I never had the P0401 code. VW will do a step by step process to basically get away with what they can with this issue. I had a new NOx...

...an EML. Carista showed P0401 fault when I scanned it - its a 102 18 plate PV with 49K on the clock. They looked at the van and diagnosed P20EE fault but software is shown as being up to date (I guess the current software does not eliminate all P20EE faults). The notes sent to me show they...

Bit of an update to the saga garage has done an scr reset forced regen and reflashed ECU EML has come back on with p20ee code and egr insufficient flow within 60 miles but no adblue countdown as yet

After speaking to previous owner he said it had a dpf clean by a proper company a year or two ago We tested the adblue injector it was atomising but slowly and not much adblue was dosed but we have nothing to compare with if it's normal or not

...expect to see less than 25ppm under these condition (even below 10ppm with the updated ECU software). The above might actually explain the P20EE faults in earlier log. I believe the NOx sensor works correctly (wake up, live data). Assuming the values reported by sensor are of right...

...I can't say anything definite on these - I believe they relate to recent P204F.... Note the mileage and time in freeze frame on P204F and P20EE are the same... Re the fault P046C - a proposal about testing "specified value" vs. "actual value" was below Exhaust...

ok cool thanks, there was no light on the dash so, awesome! cheers

There is only one fault code stored: 31103 is VW equivalent of OBD-standard P20EE. Without warning light on dash there is nothing to worry.
