Auxiliary Ventilation retrofit

[RedarT]

Hello,
has anyone successfully enabled Auxiliary Ventilation with VCDS? I tried to enable it through HVAC module but the following malfunction appears and nothing shows up in multifunction display(advanced menu is enabled). Mine is a MY2008 (pre-facelift), 1.4

It's a cool feature that does not require an extra module. I know this is part of the Auxiliary Heating option, but the heater is not required for some fresh air!
Thanks!

Depends as there are 2 aux heater systems, 1 is the additional heater unit for mostly Nordic countries to prewarm the car without engine being on & the other is what all dervs have to get the car warmer quicker when started.

Why would it need either, to just run the fan with the ignition off? Do you suggest that it is not possible to enable just the ventilation without a heater?
