An update on my issues regarding DPF and DPS fault codes on my 2.0 TDCi 2WD 140.
It went away for a short period, but didn't last. Basically ended up with what seemed like almost all the DTCs associated with the DPF system. "Soot accumulation", "DPF perfomance", "Pressure Sensor Circuit" etc. etc.
It may have just needed a new DPS, and a regen, and all would be fine, but looked at the sort of money a sensor was, and it wasn't much, but wasn't guaranteed to fix the issue. With the potential for a new DPF required, I decided to just cut my losses and found a local tuning garage online which solved my DPF issues forever (plus a complimentary ECU remap to disable DTCs and regen attempts while taking the engine to 185HP).
£450 later and I no longer have any worries about the DPF or EGR, and won't ever have (from a technical perspective) in the future.
Nice bonus is the remap has made the engine much smoother, and MPG improvement on the in-car trip computer is showing about a 5 - 10% improvement. But am going to get real data on the next few fill-ups.
Would recommend this course of action personally if you don't mind the potential pitfalls.
