2013+ is DOC(Diesel CAT?) - DPF - SCR.On my 11’, there’s no SCR, it’s CAT, NOX then DPF. So 13’ and up its CAT, SCR then DPF??
I agree with the comment on the early models without any of this stuff. Wish it was still that way. Firm believer in KISS(Keep It Simple Stupid).
To the OP, not sure if you have ALFAOBD but have read postings regarding the ability to complete stationary desoot. Not sure if that would help you out or not but maybe one more thing to try.
