The aux heater kicks out alot of smoke when running. Is there are
quick cure for this (can it be cleaned out. If left running does the
smoke stop?) or does the unit need replacing.

We are turning the heater off so that it is not used - which is
probably making the situation worse as it is leaving a small amount of
unburnt fuel in the unit.

There is a heater that burns diesel to heat the cabin and speed up the
warm up of the engine

It should. The handbook for my 2000 9-3 recommends running the heater in
the summer to prevent unburnt fuel collecting and causing it to smoke, but
here it is referring to those machines with the optional parking heater
upgrade. My TiD has the heater but it's only used when the donk is running
(when ambient air temperature is under 5 degrees and the coolant temperature
is under 75 degrees).

I'd try running the unit for a bit to see if it clears up; what fuel do you
use in it? I've only run the 9-3 on Shell since buying it in May and it
didn't use the heater until November, but there's no smoke from it.
