As per suggestion, I'm starting from scratch from previous thread. I got car back and did autoscan. I will start by checking at lift pump and work upwards from there. On previous thread mentioned DPF Regen frequency fault which has not re-appeared. I did add a dpf cleaner additive and not sure if that did the trick but for the last month or so that code has not retrned. UNfortunately, there is now an EGR code. Last thing that was done was a fuel injector replacement that had higher than normal return. The new injector seems to have solved high return issue, but this EGR code popped up and still low fuel pressure.
