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...

...So i have just been out and plugged it in, there is 18 faults! :eek: P20EE, which is SCR Nox Catalyst Efficency Below Threshhold Bank 1 Engine 31103, ABS 00128 08208 08216 08217 08338, Instument Cluster 13635840, Airbags 13635840, Parking/Steering Assit 13635840 13893632, Cental Electronics...

I recently had the engine Amber light come on constant, stopped and called VW , they sent out AA and he found code 31103 but no info? He suggested deleting the code, continuing on my journey (92miles) and take it in to VW to double check. The fault hasn't returned, the adblue reads 1800m. my...

...Bank 1 [the van has only had short runs this last week so guess this is re-gen connected?] ABS 00397 - Display test, blue segments [this cleared when I re-set tyre pressure values] Engine 31103 [no text, just the code] I'm not going to panic as there's no worry lights on the dash.

...with Carista just to see they fade away - after a couple of runs. The reason being that this far I have seen more than 20 times the fault (31103) surface up to “confirmed” level and within a few startups fading down to “pending” and eventually disappearing from Carista. But still seen by...

...came on, I think it was without cruise, flat steady speed/terrain, approx 60 mph Interestingly, I've been reading up on other threads and the 31103 I think can be linked to adblue? If so, that might make sense as it was topped up the day prior. Before top up circa 2000 miles left, after...

31103 = P20EE - SCR NOx Catalyst Bank 1 - Efficiency too Low. This is unfortunately very common, usually harmless, but there are also quite opposite cases... P20EE is standardized OBD emission fault code and 31103 is just VW equivalent, here they are actually just one fault. As you mentioned...

Thanks - nothing plugged in at all?

02256 - will prob be you have left something in the 12v socket or OBD2 port draining power when van is sleeping - or a dashcam running 24/7? @mmi found: In the VCDS coding for plain "31103" 31103 - SCR NOx Catalyst Bank 1 P20EE 00 [039] - Efficiency too Low T6 Fault Codes? .

Wow! I'll definitely check them out individually...

Hmmm... I'd say too many... to be real ones..:confused: - too bad Carista doesn't show time stamps of the faults. 31103 = P20EE - definite yes - a common one. 00397 Tyre pressure warning- yes. Central electronics 03303, 03304 - side sliding doors - possible. All the sensor faults 005xx...

The faults are "explained" as follows: 31103 - SCR NOx Catalyst Bank 1 -- P20EE 00 [036] - Efficiency too Low and 33262 - Reductant System Performance Bank 1 -- P204F 00 [096] - Malfunction The first one is unfortunately quite common and the root cause is/was unknown even to VW. A software...

...should not have anything to do with (missed or unfinished) DPF regens. Did the emissions light stay on till your visit to the dealer? The dealer has the fault code in their records - perhaps a call to get that? Just the code is enough (should be a few digits, something like 31103, P20EE, etc.)
