Approx 1200 miles - I never thought to record the mileage when topping up the as blue. I may have overfilled it. Will it eventually return to normal when I’ve used more adblue?
On a T6/6,1 the DPF and SCR/CAT are a combined unit - so be very careful the chemicals you use are also safe for the SCR and you don't damage that.

By my reckoning, seeing as AdBlue came in 2015, so there shouldn't be any CAAA,CAAB,CAAC,CFCA engines used beyond 2015. Not sure why they are listed as 2020, unless they continued in non European markets until 2020?
Thanks for the reply - I’ve recently had the DPF cleaned and engine light came back on after the clean. The cleaner guy then said my adblue was crystallised so he cleaned that also. Worked ok for week and drove lovely now this new code up as in post. Before the dpf clean it was code P2020 so...
