Auxiliary Heating - T6.1

[stefmarz]

Hi there,

I would like to ask you an explanation on the Auxiliary Heater which I could not find anywhere as for the T6.1 apparently they changed slightly the system.

There are 2 main modes: Heat Continuously or Heat Immediately. First of all, I guess the first one will keep heating until you turn it off and the second one will heat for 60 minutes or so (depending on the timing you put in the settings). Correct?

In both methods, the heater will start heating and then after 20 min or so, it stops.. then consequently the temperature drops in the van.. and then it starts again. So it is very intermittent, I could not find the way to make it run continuously without stopping. Is this normal?

Thanks a lot for your help but I could not find this answer anywhere.

I haven't got a T6 - 1 but if the system operates like the T6 parking heater then it won't be on all of the time. The heater will only work on the continuous setting until the cabin temperature reaches the temperature level that you have set, then it will cut out. It should re-activate when the cabin temp drops below that set level thus returning it to the correct temperature.

It would help to know which vehicle you have? I would guess it is not the Ocean, and you do not have the Diesel Parking Heater bu only the Webasto Engine Coolant heater that runs for only a limited time as it runs off the Engine Battery only.

Ok, perfect. So the intermittence is normal. My issue is that actually when it reactivates the temperature has dropped below the level that was reached.. just my experience so far.

I have a California Coast Edition with VW Auxiliary Heating as optional

The actual VW code for the Auxiliary Heating optional is "7VG"

Well it would. That sounds normal to me.

The van has no insulation within the body panels, so the internal temp will drop quite quickly once the heater stops.

I agree. I was wondering if there is a way/ mode to make the auxiliary heating work permanently (and not with its usual intermittence)

The only way to do that is to stop the cabin temperature from reaching the level set e.g leaving a window open. However, that would rather defeat the object. The system is merely working in a similar manner to a home central heating system where the boiler isn't running all of the time, responding to signals from the room thermostat.

The temperature sensor is in the R cabin step air intake.
If the temperature level is set very high then you get full blast then shutdown then restart.
The trick is to set a lower temperature to get more continuous operation. It is not a very sophisticated system but, leaving the R cabin window open 1 or 2 cms for ventilation, which is important, fools the temperature sensor to keep the heater on longer.

Others on the forum have fitted a Webasto auxiliary temperature sensor higher in the van, which seems to work better to maintain a constant temperature.

Cool, thanks. I will explore that option then.

Check the B pillar with the , I think R hand cab door open, and there should be 2 labels detailing which heaters you have fitted.
A Webasto Coolant Heater and the Parking Heater which could be Webasto or Eberspacher. I’m not sure if a secondary temperature sensor can be fitted for the Eberspacher. Also both heaters, if factory fitted, have special VW specific software so that some of the ancillary equipment, such as sensors etc: will not work without flashing the heater specific software that disables the VW Heater Control Panel.

Sorry being a bit thick and struggling with the aux heating but what do you mean by R cabin?

Right side, Cabin step well.
Drivers side RHD vehicles, Passenger side LHD vehicles.

I’m trying to wild camp in the winter, but I can’t get the heater to come on again after two sessions eg two hours in the evening followed by two hours the next morning then it won’t work.. is this normal?

 

[andyinluton]

Yes if you are using heat instantly - it has a maximum run time of 2 hours before the van needs driving to reset it.

You need to use heat continuously if camping.

Once you have locked the system by hitting the limit on heat instantly, heat continuously won't work until you've been for a drive.

As per @andyinluton Heat continuously is your friend.

Hope that helps

[Holly]

When I use heat continuously it goes off after about an hour and three quarters.. I must have a fault.. thank you

 

[Stu@rt]

Hi Holly, what setting (number) have you selected? Does the yellow symbol disappear when it goes off, or is it just cutting out as temperature has been reached? Is it possible that you haven't driven to reset a previous use of Heat Immediately?

 

[andyinluton]

How are you turning the heater on?

Hi Stuart, sometimes it works and sometimes it doesn’t! If I can’t get heat continuously or heat immediately to work then the key fob usually does but only for under two hours and if I use it in the evening and again in the morning and don’t drive anywhere it won’t work the next evening. What are ‘rules’ about how many times each of the different settings work without moving? The manual is not helpful..! Thank you Holly

 

[Arnoob]

It will take some time before the heat continuously really starts up. You have to be patient.
Heat immediately will stop after max 180 minutes and can only be reinstated after a 6 km/h drive. It took some time before I got this ...
