Update - have spoken with tuner and he says likely to be related with something else such as, boost leak, inlet manifold leak or carbon build up, oil breather system or injectors etc.

He also said the visible smoke test with a dpf car is only related to Euro Zone 6 cars 2014 onwards but I've looked through the MOT guide and not sure if this is true.

What he did say is my issue likely to be caused by another issue with car so I will be doing a few little jobs to start with and will go from there.

By the way my car failed on 8.2.2.2(d) if any MOT guys are on here.

My smoke test results Oil Temp = 73C
Peak 1 = 0.50
Zero Drift = 0.06
Average = 0.44
