Again, that's why it happens when you hit 70C which is pretty much the temp at which regen is allowed.
Maybe you can try to disconnect the battery for 30 mins and reconnect to see if this condition stops. But that's just a temporary fix to clear the temporary ecu/ dde memory.
You didn't answer me this: did you log fuel, maf, and egt values to compare before smoke and during smoke? That can help us point it out for you.

Just logged egt temp and smoking seemed to start when temp got upto around 270 |
Just took it over to a garage that I know as the fella used to work for bmw and he's convinced it's trying to regen
