Hello
We had to remove the secondary air heater from a VW Transporter T6 van and I want to code the whole unit out so that it doesn't show any faults. If I go to CAN gateway and select Installation List the 0B - Sec. Air Heater is not in that list so I can't just deselect it. I went to 08-Auto HVAC but the Long Coding doesn't mention anything about a secondary air heater (On the 2020 T6.1 that's where it normally is).

If I don't code out the Secondary Air Heater sometimes I will get a faults at the Auto HVAC module saying that there is miscommunication somewhere.

Autoscan below.

it's a 'known' thing that on these 7E0 BCMs, the secondary air heater pops up on some autoscans.
i am not sure what to advise. is there perhaps a specific hvac unit for vehicles with a secondary heater (i assume you mean the J364 heater for the coolant, on the left hand side of the car, aft of the front wheel)

No I mean the rear heater that is located at the right hand side (drivers side UK) at the very back of the van. This is only on the shuttle vans.
what if I pulled the fuse? Just need to find it.

if you already physically removed the unit and removed it from the canbus gateway, you should be relatively OK.
look in any other device for coding/adaptation where you expect this device to be linked, i.e. engine, hvac

Perhaps the heater you have removed is actually just rear heat exchanger+blower unit - a part of engine coolant circulation. Possibly similar to this --> https://www.t6forum.com/threads/my-shuttle-conversion.22025/

The Air heater unit would be on right side behind/aft of the front wheel. Also your scan doesn't have overhead control unit - 6E, which would control the air heater.

Yes you may be right. The blower had a control panel which was fitted overhead where the first row of passenger seats is.

So it seems it is impossible to completely remove the 0B - Sec. Air Heater from the installation list? I am not able to connect to it with VCDS as it has been physically removed.

The control panel looks like this:

EDIT: I think I know what you're talking about. The Air Heater that you mention is the Webasto one, which is found only in Shuttle/Caravelle vans. We do camper van conversions and we do convert many Caravelle vans which all have the Webasto heater installed behind the left front wheel. I've never seen one have an overhead control unit but if I was to install the unit is it possible to make the Webasto heater blow heat into the cabin without starting the engine? Now we fit Eberspacher Airtronic units which are powered by a leisure battery and have a separate warm air pipe which heats the cabin if people are camping over night.
Would it be possible to make the already pre-installed Webasto heater blow hot air to the cabin without us having to install another heater which costs £600+?
