Disappointingly VERY WEAK AUX-HEATING in T6.1

[JMStockholm]

Just a note, I'm sitting here at -15C, roof up, no isotop, nothing on windows etc., heater at 6 and its pumping out enough heat to be cosy, rather loud though. Although I have a problem with the heater not starting sometimes, think it has to do with the movement sensor that turns the heater of when driving as when the problem occur I have manage to get it working again by driving around for 5 min, stopping and then try again. Although this is the first time in 6 months ownership that I had the problem, so it might be associated with the cold. Anybody had the same issue?
Edit: Found this trick to avoid warm air blowing on, and offsetting, the temp sensor.

Edit2: this post says that if you have problems starting the continuous (aux) heater, and tries the immediate (engine/cab) heater, you have to drive around to be able to start the continuous heater again. I think I did that once. VW really made operating this unit super confusing.
Edit3: After reading up on how the heater works, I think that the footwell, where the sensor resides, was warm when I parked so the heater didn't start. Then I tried the engine heater and as a consequence inhibits both heaters until you drive >6km/h. After understanding this I open det door when I stop and all works fine since. Sleeping downstairs, at setting 4 with -15C outside, no window covers or anything, it's absolutely fine, but I'll get some window covers and an Isotop just to lessen the draft from the canvas and windows. https://www.caliboard.de/topic/2207...haltet-sich-ab/?do=findComment&comment=380334

Our 24 plate Ocean, purchased March 24. Heater has always worked fine. Albeit once we got round the controls. Did a pub stopover last night NYE in the Peak District. Absolute dreadful night, strong winds, torrential rain and I guess around 5°C.
Heater set at 5 all night. Really warm and toasty, maybe a little too warm I'm our sleeping bag with nothing more than my undercrackers on

Have you been starting the aheater using the Remote Control?
If so, that is Immediate Heat Mode and has a maximum runtime in total of 120 mins before you have to reset it by driving a short distance.
Continious Heat Mode, via the Control Panel only, has no such limitations and can be used as long as you have sufficient leisure battery power or diesel fuel. It can also be used when driving if required.

Yes, I know about the two separate heaters controlled from the very confusing single control panel, and remote only operating the normal engine/cabin heater in the Cali. So, no it's not that. There is a superlong thread about problematic Cali heaters on the german forum that I'm slowly working my way through. https://www.caliboard.de/topic/22071-luftstandheizung-schaltet-sich-ab/page/6/ So far it seems that VW some updates to adress the weak power output by switching the exhaust grill funneling the heat away from the temp sensor, similar to the video I posted, and maybe also some adjustments to the software. However, with my problem, the heater switching of by itself, not being able to turn it on etc., so far i come in the thread there is no apparent solution, and quite a few people have similar experience as I.

I think this is a language issue. Welshgas has referred to two different ways of starting the auxiliary air heater, no mention of two separate heaters, the auxiliary air heater and the auxiliary coolant heater. Try his recommendation about using the cotrol panel to turn on the auxiliary air heater, instead of using the key fob remote.

Hmm, interesting, so it's only the aux heater that's controlled from the panel. I guess that the T6 standard engine/cabin heater is fully automatic then. I think I read somewhere that it was possible, with the OBD11, to program the engine heater to kick in when the heater is turned on with the remote, I didn't understand how that was necessary when I read it as the standard heater, heats the engines coolant and then the cabin indirectly I think.

It can only be run when the engine’s running. The temperature can then be maintained automatically.
Whilst the auxiliary diesel camping heater is also on a thermostat, unfortunately the settings aren’t in Celsius. The 1-9 levels are equivalent to approximate temperatures though, and have been posted on this forum. Main thing is to set it to Heat Continuously then you’re in control.
