The P20EE and 31103 are just different identifiers of a fault.
How did you read the fault codes - Carista, VCDS, Torque?
Have you reread the fault codes if they still exist? I've seen this code to fade away out of the reach VW OEM tool in a few engine startups. After hooking up the VW OEM tool...
Engine light can on for me again the other day - read the codes as P20EE and 31103.
Booked into dealer on weds but since then the engine light has gone off this time (happened twice before)
May as well take it into the dealer as they’ll still be able to read the codes? And then fob me off as...
Besides the infamous 31103 - SCR NOx Catalyst Bank 1 P20EE 00 [100] - Efficiency too Low -fault I have been curious about stated AdBlue overfilling causing errors in T6 engine management. So with ”promise to rescue” :thumbsup: from my VW garage :inlove: I have been “overfilling” my AdBlue tank...
...in the way the van is driving - everything feels as it should.
Are the two related, or pure coincidence?
It seems ridiculous that my battery is failing after only 18months and 14k miles.
A quick look with Carista today shows various codes - the only engine one is '31103 Manufacture-specific...
For EU6 engines most likely: 31103 - SCR NOx Catalyst Bank 1 P20EE 00 [096] - Efficiency too Low.
This is very common, usually harmless, but there are also quite opposite cases...
P20EE is the same as engine fault 31103. Search “31103” in the Forum.
0397 Tyre Pressure Warning - Pressure Loss. Dash light has been on?
6720 Rear View Camera – No Signal
As you can see 2 fault codes were recorded. After a bit of research I was fairly confident that the second code - 31103 - SCR NOx Catalyst Bank 1 was related to a problem with the NOx sensor in the exhaust. This made sense as it might explain my increase in Adblue consumption. The van was...
...Reductant System Performance Bank 1
P204F 00 [096] - Malfunction
Intermittent - Not Confirmed - Tested Since Memory Clear
31103 - SCR NOx Catalyst Bank 1

VCDS is showing that the 31103 is back on in my CXFA engine (150ps+DSG). Last time was in March (2367 km ago). Then I took it VW-service to get recorded and resetted.
Interesting thing is that it did not turn on the engine light then, and this has not either- yet.
I'll let this stay in there...
...With mine neither concerns with oil consumption, neither no mayo build up in oil-filler tube or cap.
The engine fault code on mine was "31103 - SCR NOx Catalyst Bank 1, P20EE 00 [039] - Efficiency too Low"
I’m assuming that those status messages on yours now “not ready” are because the...
@Twoguns You may find this post of interest to you. @mmi lives in Finland and seems to have the same model T6 as you. I'm not sure your problems are the same or just similar. Over to you for your advice to @mmi please.
...I have had only once engine light on (this far) and that for different fault code. Interesting thing is that I have the same fault code "31103 - SCR NOx Catalyst Bank 1, P20EE 00 [039] - Efficiency too Low" sitting in my ECU but it hasn't turned on the light.
Currently I'm driving with a...
In the VCDS coding for plain "31103"
31103 - SCR NOx Catalyst Bank 1
P20EE 00 [039] - Efficiency too Low
Grabbed the above out of the engine (CXFA) with a VCDS. It was also confirmed at the dealer. It didn't turn on the light.
