Last 5 of VIN [redacted] mileage is 112k No EML light on dash. What does fault 31103 relate to? I'm hoping these faults are easily rectified as I've only just bought the van and can't afford to spend loads on it :oops:

...the type of the van - just leave 5 last digits off. Also what's the mileage in the scan? Got a bit curious of seeing in the scan: 121 incidents :unsure: of fault 31103 - SCR NOx Catalyst Bank 1 - P20EE 00 [104] - Efficiency too Low But you don't have the EML light on? (Yellow engine symbol)

Any chance it's actually 31103 aka P20EE? https://www.t6forum.com/threads/eml-light-on-vcds-scan-implies-an-scr-fault.20638/ https://www.t6forum.com/search/251246/?q=31103&o=date https://www.t6forum.com/search/251250/?q=P20EE&o=date

Hi If it helps, I have had 7 EML's (Emissions light - not coil light) on my 2019 MY 150 DSG, and only done 5000 miles. The light never resets itself. The code is the P20EE. VW have reset the fault code 5 times, and twice more after replacing the SCR Injector valve and then 1000 miles later the...

...some Redex. The light has now gone out - most of my miles are motorway. I now have VCDS (thanks to @sippe ) and the fault code showing was 31103 as above. Looking at the data it seems it might not have had the any updates (Component R4 2.0L TDI H 02 4027). It also shows the frequency being...

How has your van been after the NOX replacement? I've just had a multitude of faults come up and one being this.... also an intermittent issue on the EGR .. as you said MPG has been going down, van is running rich and no other issues other than a drained battery one day and down 15bhp on power ...

Thanks. I'm quite sure VW has an update for the engine - which should among other things cure the fault "31103 - SCR NOx Catalyst Bank 1, P20EE 00 [236] - Efficiency too Low". The update campaign started early 2019 and last T6 engines got the update March this year. So I would recommend to...

So the EML light came on the way home tonight, and a scan of VCDS when I got home gave the following fault: 31103 - SCR NOx Catalyst Bank 1 P20EE 00 [236] - Efficiency too Low MIL ON - Intermittent - Confirmed - Tested Since Memory Clear Freeze Frame: Fault Status: 00000001 Fault Priority: 2...

The biggest issue with adblue it can crystallise in the tank and on the sensors...so they would I hope clean out the system and refill....what I’ve found it’s best not to let the tank run down too low as it will splash up the sides

There's definitely a common thread here - which is the temperature. In the cases above it seems that the fault codes are being thrown when the temperature is below freezing, which may add some weight to the theory about adblue urea concentrations! So here's my experience :-( Yesterday when...
