A bit of holiday time during this festive season meant i was able to revisit the Aux Heater install.... whilst it had made a difference and had reduced warm up a time a bit, the more i thought about the more it wasn't making me think WOW, what a difference......
So i Googled, and read.... and read a bit more.... and then for good measure, read it all again. None of the install guides mentioned an additional coding requirement on the Auto HVAC side of things....
Channel 21 on Adaptions, change your 0 to 1, press save....
What does that do, i hear you ask???
well once you have rebooted your MMI it gives you another additional setting to turn on
It now gives me the engine preheat option, rather than just aux heat and aux vent.
Time will tell if it makes a further improvement...
