I too have a one-month-old T6.1 Ocean and have just had similar issues with the heater (with wife and kids in the van complaining about how cold it was)(not fun):
Problem 1: in operation mode set to “aux heater” and activated “heat continuously” level 7, at about 11pm. Starts heating nicely. I wake up at 2am, heater is deactivated (heater led not lit, that is completely turned off, not just not blowing hot air). Isn’t it supposed to stay on until turned off by user? (Plenty of petrol in tank) So I decide to try “heat immediately” function...
Problem 2: I press “Heat immediately” and get the “Please wait” screen. Stuck on that screen for hours (literally, I was up at least two hours) without a way to exit. Panic! I have to lower the roof in the morning... will I be able to?! In the morning the screen is magically unstuck, thank the Lord. Still slept without heating tho.
VW really need to sort out the new control panel issues.
Another thing, why is it that I have to turn on the ignition to change the heater mode setting? What if it’s 11pm in a dark campground... At a minimum my daytime running lights wake up my neighbours.
Lastly, does anyone know how to do a control panel reset *ON A T6.1*? Thanks all!
