Intermittent rough engine running, turbo lag, and exhaust smell in cabin on BMW N47 diesel after DPF/EGR modifications, likely due to forced DPF regeneration cycles and lack of proper ECU reset.
No diagnostic solution to identify root cause of sporadic limp mode and regeneration cycling without CEL, and no way for DIYer or mechanic to verify if DPF values were reset properly.
