Update:

2 more commutes and i didnt manage to get the codes to re-appear, but the DPF has been regenerating and it has reduced the hesitation.

Thankfully i found that ISTA stores old logs so i managed to pull the codes:

P2251 - O2 Sensor Negative Current Control Circuit/Open (Bank 1, Sensor 1)
P0132 - O2 Sensor Circuit High Voltage (Bank 1, Sensor 1)
P2297 - O2 Sensor Out of Range (Bank 1, Sensor 1)

So first step is to inspect the wiring of the sensor. If that looks good, ill order another.

Given the problem was worst on warmup and almost completely disappears when the DPF regens, that would confirm a suspected Lambda fault. Apparently they only start working properly from 316C+. If they cannot heat themselves, this would cause fuelling issues.
