Ventilate mode

My Conclusion. Will be put test when temps drop

So auxillary coolant heater if blows at windscreen below 7 degrees will clear ice / snow as says in manual ?

You are massively over thinking things.
Forget about auxiliary coolant heaters for a bit & think about the normal van heater, it uses the hot water surrounding the engine to provide the warmth in the cab, you use the heater controls to blow that warmth onto the screen to defrost it.

Now because modern diesel engines are pretty efficient they don't get hot until they start working hard, this means on a cold morning the water round the engine takes ages to warm up so you don't get much heat in the cab for a while.

Vws solution to this is to put a little diesel powered heater in the water circuit round the engine to help warm the water quicker. They called it for sake of convenience an Auxillary coolant heater. You have no control over it in an ocean & it doesn't do anything other than make the water round the engine hot quicker. It has temperature sensor on it & it comes on automatically below about 5 degrees.


In other variants of T6.1 vans & in some countries you may get control of that auxiliary heater allowing you to for example leave it running all night in arctic conditions to stop the engine freezing, but you don't need top worry about that as its not fitted to a uk ocean although it may be mentioned in a VW transporter standard manual.

Understood, but for that auxillary coolant heater to work.
As I keep mentioning , but not 1 person has referred to it ?
Were the lower radio console is , go to vehicle settings.
There you will find supplementry heater option , a square box that you either TICK or Untick .
I presume this either enables or disables the auxillary coolant heater ??
Correct or not ?

So when the coolant heater kicks in below 7 degrees , an blows at windscreen .
It's actually the normal engine heater producing the heat ??
With the aid of the auxillary coolant heater?

Yes, sort of. The box enables the automatic function of the Auxiliary Coolant Heater that you (and many others) are describing, the one that works with the running engine in cold weather.

The Auxiliary Coolant Heater can also be chosen in the CU menu, instead of Ventilate or Auxiliary Air Heater. These are essentially the 3 options you have highlighted from the manual in your post #45.
If you chose this option, the "heat immediately" (typically via the remote control) would start the Auxiliary Coolant Heater instead of the Air Heater. You would use this to pre-heat the coolant and defrost the windshield prior to driving off.

The ventilate option is also for the "heat immediately" function but of course doesn't do any heating or defrosting as it only blows the fan. It is meant to be used in summer to displace accumulated hot air before driving off.

I'm not sure if unticking the box would affect the "heat immediately" function with the Auxiliary Coolant Heater. I would think (hope?) not but haven't tried it.

Note that T6.1 pre-MY21 vans may work a bit differently. I believe they also didn't get a remote control fob.

For those of you who would like to be further entertained by this topic, there is a (ok, but not 100% accurate) german supplementary manual: https://www.autohaus-vonkaenel.ch/media/docs/Camping/T61_Standheizung.pdf

No it doesn't, you are going to confuse @Little owl1963 even more.

On a UK spec Ocean the remote control starts up "heat immediately" or "ventilate". Ventilate just starts the dashboard fans. Heat immediately starts up the air heater & blows hot air out of the B pillar vents.

Without translating the linked document its difficult to see exactly what it is saying, but the diagrams for all modes show hot air coming out of the B pillar vents - thats what the Air heater is attached to.

Andy , have you looked in radio dash control panel ?
Under vehicle settings , supplentry heater
The SQUARE TICK BOX , no one is ever mentioning this ?
Don't think anyone knows its there?

Everybody knows it's there, every body just leaves ion the factory default, everybody's heater works on a cold morning. Why would anyone bother changing it?
If your heaters not getting hot quick enough you need to put your welly down a bit.

Think confusing bit says manual, engine coolant heater clears ice an snow from windscreen ?

By way how do you view latest software update , so no which one have ?
Think its a V Number ? Can't see it on panel

Well let's Hope that as the california has got this quick heater for winter , it actually does its job ??
Has anyone timed it how long takes to blow hot air out ?

Must be improvement of Autumn heater taking 25 mins , so must be quicker than that

I don't have a UK spec Ocean, but on mine the remote control starts up whichever option was selected last in the CU. The Coolant Heater (called Wasserstandheizung in mine) is one of those options. When I engage the system with my remote when it is set to Coolant Heater, I can clearly hear the diesel pump clicking, this at 15° outside temperature. The Air Cooler in this scenario remains idle.

As you've suggested in #52, the UK vehicles could be wired differently than mine, however, the manual referenced in #45 makes sense from the perspective of my vehicle.
