Used another hour of the fast disappearing daylight to purge both the heater matrixes again.
Flushed them through clean using a little pressure and lots of water.
Now G150 & G151 reading very similar to each other as RH and LH matrixes now seem to be in a lot better state. Ran all the basic settings again on VAGCOM to ensure flaps were all happy and in place.
Temps on the thermometers seem to read about 4 to 5c above the requested temp on the HVAC unit which seems reasonable to me and much more balanced now.
I have some heat there now but need to take it on a long run to check everything is working as it should.
What happened to the good old days when there was just a tap under the dash to turn the heater on
